If you want to unify the management of the laboratory, my personal suggestion is that the e3-lab electronic laboratory record system will be better, because it is very standardized from the laboratory record to the budget, such as the laboratory record will leave a record every time the change is made, as well as the template of the record, the tutor customizes the template, the student follows this record, and the distribution of the instrument, what time to what time of the day who uses, these are recorded to prevent the problem of duplication of arrangements, as well as the financial problems of the laboratory, Teachers can also approve in the field, and there are annotations of experimental records, so the most effective unified management of the laboratory.

The laboratory information management system is the LIMS system, which can be automatically managed from the moment the sample is accepted to the final report generation system, and can also be used for sample management, instrument and equipment management, temperature and humidity monitoring, etc. In recent years, more mature enterprises such as Hangzhou Gauss Information Technology Co., Ltd. are specialized in the development of laboratory management system software.

You go to a professional here.

The technical person in charge of the testing laboratory is one of the key positions, and his working ability and sense of responsibility are directly related to the technical operation of the institution.

The technical management of the laboratory can be summarized into six aspects: personnel, equipment, methods, facility environment, reagent standards, and technical documents.

1 Personnel management.

Laboratory staffing needs to match the workload, the technical ability of the personnel should be competent for job responsibilities, the training demand objectives and training effects should be evaluated, the training situation should be recorded, the key work should be authorized, and special circumstances must be supervised and monitored.

2 Device Management.

Equipment needs to be adapted to the testing work, equipment needs to be evaluated, new equipment must be quality acceptance, measurement traceability requirements of equipment must be verified or calibrated, verification and calibration results to be confirmed, some equipment to be verified, equipment use and maintenance to record, keep the equipment "birth, old age, sickness and death" files.

3 Method management.

The adoption of the assay must be evaluated, and the method should be validated or validated before the method is introduced into the experiment, and the method performance meets the requirements before it can be approved for use. The method of use should be current, the method standard has changed, and the laboratory should reassess its ability to use the method.

4 Facility Environment.

The environment of the facility should be suitable for the testing work, and the work should not be interfered with, and those that have a key impact on the testing work should be monitored and recorded.

5 Reagent Standards.

Key reagents should be subject to quality acceptance.

There should be management procedures for the subject matter, regular inspection, and recording of storage and use. The original test record should be traced back to the proven validity of the subject matter.

6 Technical Documentation.

All kinds of technical files and technical records should be controlled.

There should be a list of foreign technical documents, and the classification should be clear and clear. Continue to keep the drafts of external documents current and easy to obtain, and Chang Roll regularly conducts new checks. Follow-up work will be carried out as soon as the methodological standards are updated.

Updating the list of documents, replacing controlled documents, organizing personnel learning, comparing old and new standards, validating methods if necessary, and changing the technical capabilities of the laboratory. In some cases, it is necessary to apply for a change in document review, and in some cases, an on-site expansion review should be requested.

The dolomite dissolution experimental apparatus is the same as the limestone dissolution experimental apparatus introduced in the previous chapter, except that the dolomite spinning disk is replaced by the limestone spinning disk, so it will not be repeated here.

Similarly, the dolomite dissolution process is understood by measuring the conductivity of the solution by a conductivity meter and recording its changes by a computer. In this experiment, there was a linear relationship between the total hardness and conductivity of the solution

th（mmol·l-1

s·cm-1

Correlation coefficient r=

Therefore, the change in total hardness during dissolution can be obtained by the automatic recording of the conductivity of the solution, so that the dolomites dissolve rate is.

r=（v/a）（dth/dt）/2

where: v is the volume of the solution; a is the surface area of the rotating disk; Factor 2 indicates that 1mol of dolomite dissolves to produce 2mol of hardness.

Figure, (b) are low CO2 respectively

partial pressure and high CO2

Typical experimental curve at partial pressure. The straight segments show that the total hardness increases approximately linearly with time at a fixed rotation rate and/or a fixed carbonic anhydrase concentration.

The thickness of the diffusion boundary layer during the experiment can be given by the following formula of Levich (1962).

Swift Eyes D)1 3

where: d is the molecular diffusion coefficient; is the viscous coefficient of water motion; i.e. rotational angular velocity.

Therefore, in this experiment, the minimum speed of rotation is 100r·min-1

Hour = 5 10-3

cm, while the highest is 3200r·min-1

time = cm, because the Reynolds number (re=r2, r disc radius) is below 2 105 for all experiments

So it is ensured that the experiment is carried out in the case of laminar flow.

Shengyuan Guangtong LIMS system for small and medium-sized laboratories to provide a short, concise, powerful, practical fool-style laboratory management information system, can meet the basic needs of some small and medium-sized laboratories at the same time, the system adhering to the advanced concept of scientific and fine management, can comprehensively improve the level of laboratory management, to achieve "informatization, standardization, intelligence, paperless" office, become an indispensable auxiliary software for small and medium-sized laboratory management.

The integrated laboratory management system adopts the network version of the BS architecture, which has good scalability, and can realize the full coverage of the laboratory, multi-dimensional, and data visualization of the whole life cycle of "man, machine, material, environment, method, and measurement"."Intelligent real-time management and control.

The most important thing in the laboratory is the instrumentation and equipment, consumables and teaching, and the laboratory management system must include the management of these three aspects. Therefore, the functional module of the laboratory management system must include the following aspects: 1. Instrument and equipment management module; 2. Consumables (low-value products) management module; 3. Teaching management module.

Among them, the teaching management module can add laboratory appointments, as well as the review and review of familiar knowledge that must be determined before the experiment, such as experimental principles, experimental processes and experimental data processing.

The whole system should closely unite teachers, students and laboratory managers, and the functions of the system are:

The function of the three identities of users logging in to this system is the vertical code family:

The functional modules of the laboratory management system are:

1. Laboratory management.

The laboratory management module includes the system's announcement management, user management, and data dictionary.

2. Experimental teaching management.

Experimental teaching management refers to the overall management of the teacher's teaching process, including the management of teaching plans, teaching resource uploads, documents, student data reports, and grades.

3. Instrument and equipment management.

Management of the addition, storage, use, maintenance, and loss of experimental equipment.

4. Management of low-value products and consumables.

Management of addition, storage, use, replenishment and loss of low-value products and consumables.

5. Laboratory construction and equipment procurement.

management of laboratory construction planning steps and management of equipment procurement process; There are three types of equipment: office equipment, scientific research equipment, and teaching equipment. If you need to subscribe, fill in the subscribe** and then approve it according to the approval process. The purchasing department generates a purchase list statistically.

6. Laboratory evaluation and evaluation.

Evaluation of laboratory management and teaching by system users is integrated with the model limb meter.

7. Data and reports.

The system forms queryable details and statistics according to the data of the entered equipment, low-value products and consumables, etc., and can form reports.

1. Document preparation.

The document preparation team prepares the document in accordance with the requirements of the CNAS CMA. The document hierarchy is generally divided into four layers: quality manuals, program documents, work instructions, operating procedures, records and forms.

The workload of document preparation is large and the relevance is strong, so it is necessary to avoid copying and copying, and to tailor it to the individual. The process of document preparation is actually a process of standardization. When compiling documents, the quality policy and quality objectives should be considered simultaneously.

2. Document release.

Before publishing, the old files and old record forms should be cleaned up. After the approval of the management, the quality manual and procedure documents are issued, and the second and first level documents (work instructions, operating procedures, records and forms) are also issued and effective.

3. Personnel training.

Develop a training plan based on your needs. Document writers train the backbone of each department on management system documents. Organize the backbone of each department to learn the CNAS CMA accreditation and accreditation standards, and conduct on-the-job training for new employees.

Formulate the job requirements of personnel in key positions, participate in continuous training in a timely manner, and keep the technical files of personnel in key positions. Technical personnel should also participate in the training of testing standards and testing technology.

4. Implementation of management system.

All departments according to the requirements of the system documents to implement the operation, standardize the filling of records, issue the whole process of testing reports, the problems found in the operation process, all departments should timely summarize feedback, in order to timely correct the documents or standardize the existing practices, to avoid the phenomenon of "two skins" between the file and the actual operation, and to carry out self-examination in a timely manner after the implementation.

5. Internal audit.

The purpose of an internal audit is to verify that the management system is operating in accordance with the requirements of the management system documents and accreditation criteria on an ongoing basis. An internal audit team is set up to prepare an internal audit plan and audit it by department. Compare the actual operation with the degree of compliance with the document approval standards, find non-conformities and problems, and supervise and rectify the non-conformities.

When rectifying, we should avoid going through the formality and find out the cause of the problem. Internal auditors should try to avoid auditing their own departments, and the results of internal audits should be reported to management.

6. Management review.

The aim is to ensure that the system continues to be relevant and effective, and to make necessary changes or improvements. Generally, it takes the form of conference review, usually once a year.

The inputs of the management review are: the completion of the implementation of the quality policy and quality objectives, and the suitability of the policy objectives; the results of proficiency testing or laboratory comparisons; non-conformance to the corrective and preventive measures taken in the testing work; Customer Feedback, Complaints and Customer Satisfaction Surveys; Summarize the results of internal audit and external audit; Summary of quality supervision; Summary of the implementation of employee training; resource satisfaction; Summary of the work of each department.

The laboratory management system can help the laboratory to achieve efficient and standardized management. Based on the needs of laboratory work quality, customer service, data security, work efficiency, management section execution and rapid development, integrating order management, sample management, report template, quality management, equipment management, and data analysis, after more than ten years of precipitation, the laboratory information management system independently developed by Qingsoft Qingzhi has carried out comprehensive information management in all aspects of laboratory business acceptance, sampling, analysis, review, approval, statistics, etc., to ensure the correctness of data transmission in the testing process. The smoothness of information circulation, the standardization of business organization, the timeliness of data statistics, and the traceability of data or manuscript reputation have improved the efficiency and management level of laboratory work.
