The problem of doing instrumental analysis, the main shortcomings of instrumental analysis are:

You can go to the pharmaceutical factory and try it.

Hello: all walks of life do well, the salary will be very high, now the instrumental analysis industry is more miscellaneous, you are learning to be chemical, instrumental analysis is a professional course, if your unit analytical instruments are more complete, then you can learn in the original unit for about 2 years, remember, do the instrumental analysis industry, must lay a solid foundation.

The following instruments must be able to operate, and it is best to troubleshoot and establish sample analysis methods.

gc,gc-ms,hplc,hplc-ms,icp,icp-ms

Ion chromatography. These five categories of instruments must be mastered, and one of them must be proficient.

When you are almost done with instrumental analysis, it is recommended to take the quality engineer exam, cooperate with testing and management, and it is best if you can get the intermediate level.

I don't know how your foreign language is, if the foreign language is okay, you will eventually go to foreign companies and well-known third-party testing groups for development.

I know a person who is engaged in chromatography detection with quality management, with an annual salary of 160,000!!

1. Study in the original unit for one or two years, focus on instrument analysis, pay more attention to the experience of using analytical instruments, and apply for employment in instrument sales companies when the time is ripe.

2. After accumulating a certain amount of experience, the sales revenue will be high, and there is no way out for the analysis, and the income will not increase.

Summary. The main disadvantages of instrumental analysis are: 1. The cost is high, and expensive instruments and equipment need to be purchased; 2. The operation is complex and requires professional and technical personnel to operate; 3. The measurement accuracy is limited by the instruments and equipment; 4. The measurement time is long, and the measurement results cannot be obtained in time.

The main disadvantages of instrumental analysis are: 1. The cost is high, and expensive instruments and equipment need to be purchased; 2. The operation is complex and requires professional technical personnel to operate; 3. The measurement accuracy is limited by the previous life of the instrument and equipment; 4. The measurement time is longer than that of the limb, and the measurement results cannot be obtained in time.

I'm still a little confused, can you be more detailed?

The main disadvantages of instrumental analysis are: 1. The cost is high, expensive instruments and equipment need to be purchased, and the maintenance and maintenance of instruments and equipment also require certain expenses; 2. The operation is complex, and professional technicians are required to operate, and the operation process also requires a certain amount of virtual time; 3. The measurement accuracy is limited by the instrumentation and equipment, and the higher the accuracy of the instrument and equipment, the higher the accuracy of the measurement results; 4. The measurement time is long, and the measurement results cannot be obtained in time, and the measurement process also takes a certain amount of time.

High cost, number of samples, etc.

Judging from the provisions and requirements of the hand orange instrument analysis method, there are mainly the following shortcomings:

1. The professional level of the instrument operator is high: the instrument analysis method needs to have certain instrument operation skills and professional knowledge, and the operator needs to go through professional training and practice, otherwise the accuracy of the test results may be affected.

2. Instrumental analysis can only determine known substances: instrumental analysis can only determine the content of known finch-eliminating substances, and structural identification is required for the analysis of unknown substances, which needs to be analyzed in combination with other technical means.

3. Pollution and danger to the environment: Some instrumental analysis methods need to know the use of toxic and harmful reagents and solvents, which may cause pollution and harm to the environment and the human body if not used or disposed of correctly.

Instrumental analysis is a method that uses advanced instruments and equipment and related technologies to analyze and detect samples. Common instrumental analysis methods include mass spectrometry, spectroscopy, chromatography, electrochemical analysis, etc.

Instrumental analysis refers to the analytical method of sampling special instruments for qualitative analysis, quantitative analysis or structural analysis according to the physical properties or physicochemical properties of substances.

Instrumental analysis can be divided into: optical analysis (including emission spectrometry, molecular absorption spectroscopy, atomic absorption spectrometry), electrochemical analysis (including potential analysis, conductivity analysis, coulombic analysis, polarographic analysis), chromatography (gas chromatography, high-pressure liquid chromatography), mass spectrometry, etc.

Commonly used instruments are: ultraviolet-visible spectrophotometer, infrared spectrophotometer, potentiometer, conductivity meter, coulomb meter, polarograph, gas chromatograph, high-pressure liquid chromatograph, mass spectrometer, etc.

Chemical analysis is a constant analysis, which can be understood as a higher concentration or content.

Whereas, instrumental analysis is aimed at trace and trace analysis, i.e., low concentrations or concentrations.

For example, if the error is 1, then the relative error of a chemical analysis may be 1%, while that of an instrumental analysis may be 10%.

Of course, in reality, the absolute error value of instrumental analysis is much smaller than that of chemical analysis, but the relative error is large.

Therefore, the so-called higher accuracy of chemical analysis than instrumental analysis refers to relative error, not absolute error (it is meaningless to simply compare absolute values).

It has continuously enriched the connotation of analytical chemistry and made a series of fundamental changes in analytical chemistry.

With the development of science and technology and the progress of society, analytical chemistry will face more profound, broader and more drastic changes.

The current disadvantages are noisy for the upgrading of analytical instruments.

The continuous innovation and application of new methods and technologies are important contents of these changes. Therefore, instrumental analysis is in the analytical chemistry courses of colleges and universities.

The position of the department is becoming more and more important.

In order to enable the people they have trained to calmly meet and face the challenges of science and technology in the new century, many local colleges and universities have divided their instruments.

It is listed as a compulsory professional basic course for students majoring in chemistry and other majors. Instrumental analysis textbooks adapted to the relevant majors of local colleges and universities are one of the important contents of textbook reform.
