Product Introduction:

Solid phase extraction is the use of solid adsorbent to absorb the target compounds in the liquid sample, separate them from the matrix and interference compounds of the sample, and then eluent elution or heating desorption, to achieve the purpose of separation and enrichment of the target compounds (namely sample separation, purification and enrichment), the purpose is to reduce the sample matrix interference, improve the detection sensitivity, it is used in all kinds of 12 solid phase Extractor Food detection, agricultural product residue monitoring, medicine and health, environmental protection, commodity inspection, tap water and chemical production laboratory.

Operation procedure

The operation is slightly different according to the different mechanism of packing retention (packing retention target compound or retention impurity).

1. The filler retains the target compound

l activation ---- removes impurities in the column and creates a -constant solvent environment.

l Loading ---- The sample is dissolved in a -fixed solvent, transferred to the column and the components retained on the column.

l Shower ---- to remove most of the disturbance.

l Elution ---- A small volume of solvent is used to elute the substance under test and collect it.

2. Retain impurities in the filling material

Solid phase extraction operation - usually has three steps (see Figure 2):

Activation - removes impurities from the column and creates a stable solvent environment

l Loading -- The sample is transferred into the column, where most of the target compounds are drained with the sample base solution and impurities are retained on the column.

l This step starts the collection

Elution - Rinse the components with a small volume of solvent and collect them, then merge the collected solution

The 12 bit solid-phase extraction instrument is often used for removing pigments in food or pesticide residue analysis

Test tube tray or bracket with different aperture and number of holes can be customized

Main features:
1. Transparent machine made of organic glass, strong.
2. Anti-cross contamination, anti-atomization vacuum tank design, simple and fast operation.
3. Phase-free operation facilitates collection of analyte components and processing of small volume samples.
4. The solid phase extraction device can be equipped with a large capacity collection vessel, which can process samples in batches or individually.
5. The wall thickness of the vacuum tank is uniform, so it can withstand high negative pressure above -0.096Mpa, and there is no deformation during long-term high-pressure use.
6. The extraction column tray is made of ultra-high polymer material, which is beautiful and does not deform when used under high pressure for a long time
7. The internal test tube rack is made of PTFE, so it has very high.
8. Uniform pressure throughout, good airtightness, and strong stability
9.12-bit solid phase extractor with good extraction speed and inductivity \\ Easy to control and adjust.
10. Multi-channel can be independently controlled, joint.

Columns shall not collide under any circumstances \\ solid phase extraction column bending or strong vibration;

When the column and chromatograph connection, valve or pipeline - must be cleaned;

Pay attention to degassing of mobile phase;

Avoid using solvent with high viscosity as mobile phase;

The sample shall be purified;

Strictly control the sampling quantity;

After analyzing the solid phase extraction column every day, the residual samples in the sampling valve should be cleaned;

At the end of each day, the column should be cleaned with appropriate solvent;

If the column is not used for a long time, it should be preserved and sealed with appropriate organic solvent.
