typical application:

Typical application one, QUECHERS method of rapid sample pretreatment for pesticide residue inspection:

1. JXQE-16A automatic QuEChERS pre-processing all-in-one machine homogenizes 10g of samples and adds 10ml of acetonitrile;

2. JXQE-16Aautomatic QuEChERS pre-processing all-in-one machine oscillates for 1 min, add 1g of sodium chloride and 4g of magnesium sulfate;

3. The JXQE-16A automatic QuEChERS pre-processing integrated machine oscillates for 1 min and centrifuges at 5000 rpm for 10 min to aliquot 1 ml of the acetonitrile layer and add 250 mg of magnesium sulfate 150 mg PSA powder;

4. The JXQE-16A automatic QuEChERS pre-processing integrated machine oscillates for 1 min, and the supernatant is centrifuged and analyzed by GCMS.

Typical application 2: LC/MS method for extracting OTC drugs in water and sludge cake:

1), sample preparation

Put 3.76mL water, 20uL cetirizine, diphenhydramine and diclofenac, and 140μL acetaminophen into a 50ml centrifuge tube. For the sludge sample experiment, weigh the 2.5k freeze-dried sludge and add the same amount of water and medicine as mentioned above. Add 10mL acetonitrile and add it to the EN extraction tube. After JX-QE16 works with a 50ML adapter for 1 minute, it is centrifuged at 4000rpm for 5 minutes.

To

Dispersive solid phase extraction: Take the supernatant (about 7 mL) and place it in a d-SPE dispersive solid phase extraction package. Use the 15ML adapter for JX-QE16A to work for 1 minute, and then centrifuge at 4000 rpm for 5 minutes. Then the extracted supernatant was transferred to a clean 15mL centrifuge tube and evaporated to dryness with nitrogen. Use 1.875 mL of 50:50 acetonitrile and water to make a sample solution.
