Typical application:
Typical application one, QUECHERS method of rapid sample pretreatment for pesticide residue inspection:
1. JX-QE16 automatic QuEChERS pre-processing all-in-one machine homogenizes 10g of samples and adds 10ml of acetonitrile;
2. JX-QE16 automatic QuEChERS pre-processing all-in-one machine oscillates for 1 min, add 1g of sodium chloride and 4g of magnesium sulfate;
3. The JX-QE16 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 JX-QE16 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 7mL) and place it in the d-SPE dispersive solid-phase extraction package. Use the 15ML adapter for JX-QE16 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.
