Solid phase extractors use safety measures, solid phase extraction operation procedures

Hello Beijing Deshi Technology****(

Answering your questions:

Incorrect use of solid-phase analyzers can still lead to electric shock or fire incidents. To prevent hazardous situations, follow the guidelines below when installing, using, maintaining, and cleaning the unit. In order to ensure your safety, prolong the service life of this machine, and maintain the quality of use of this machine, please read the following safety precautions carefully.

1.Before using this unit, you must read and understand all user guidelines.

2.Instruction manuals must be kept in a safe place in case they are needed in the future.

3.The warning instructions on the machine and its instruction manual must be strictly followed.

4.All instructions for use must be followed.

6.The power cord should be properly set up to avoid being stepped on and crushed by objects.

7.AC power outlets and extension wires should not be overloaded, as overloading can cause fire or electric shock.

8.Do not insert any foreign objects into the machine through ventilation holes or openings, and do not spill water or other liquids on the control panel of the case.

The solid phase extractor of the Shengyang brand uses a solid adsorbent to adsorb the target compounds in the liquid sample, and this should be very suitable for you.

Depending on the resin retention mechanism, where the resin retains the compound of interest or impurities, the procedure varies slightly. There are generally four steps in the SPE operation:

1.The resin retains the compound of interest.

The activation --- removes impurities from the cartridge and creates a solvent environment.

--- loading, the sample is dissolved in a solvent, transferred to the column, and the components remain on the column.

Rinsing --- remove interferences to the greatest extent.

The analyte substance is eluted --- a small volume of solvent and collected.

2.The filler retains impurities.

There are generally three steps in the SPE operation:

Activation – Removes impurities from the column and creates a solvent environment.

Loading – The sample is transferred to the column, where most of the target compounds flow out with the sample base and impurities are retained on the column, so the collection begins at this step.

The components are washed down with a small volume of solvent --- eluted and collected, and the collected solution is combined.

This condition is mostly used to remove pigments in food or pesticide residue analysis.

The solid-phase extractor effectively integrates all steps of solid-phase extraction into one platform, which can fully realize the fully automatic operation of the entire solid-phase extraction process (activation, sample loading, leaching, drying, and elution), which greatly improves the efficiency of sample pretreatment, frees analysts from tedious pre-treatment work, and makes sample pretreatment faster and more efficient.

SPE technology is based on the theory of liquid-solid chromatography, and uses selective adsorption and selective elution to enrich, separate and purify samples, which is a physical extraction process that includes liquid phase and solid phase. It can also be approximated as a simple chromatographic process.

SPE is a liquid chromatography separation principle that uses selective adsorption and selective elution. The most commonly used method is to make the liquid sample solution pass through the adsorbent to retain the measured substance, and then select an appropriate strength solvent to wash away the impurities, and then quickly elution the measured substance with a small amount of solvent, so as to achieve the purpose of rapid separation, purification and concentration. It can also selectively adsorb interfering impurities and let the measured substances flow out; Or adsorb impurities and the measured substance at the same time, and then selectively elute the measured substance with a suitable solvent.

Introduction of ZZ-8L CNC solid phase extractor.

ZZ-8L CNC solid-phase extractor accurately controls the flow rate of various solutions through the column in a numerical control manner, and has the functions of positive pressure elution, large-volume continuous sampling and timing, which ensures the best rate and purity of the target analyte, reduces relative deviation, avoids cross-contamination between samples, and can process multiple samples at the same time to improve work efficiency.

Features of ZZ-8L CNC solid phase extractor.

1. Positive pressure extraction and elution.

2. It can be continuously injected in large volumes.

3. The numerical control pump accurately controls the speed, works independently between the sixteen channels, and the extraction consistency is better than that of the vacuum pump 4. The flow rate can be fine-tuned, and the control and adjustment are convenient.
