    ◆ Basic configuration:

    1. A set of JX-QE-CL system machines.

    2. Freeze grinding module 1.5-2.0ml*24 set, 7-10ml*8 set, 25ml*2 set.

    3. PTFE tube 15ml, a set of 15ml. A set of 25ml stainless steel grinding tank, a set of 25ml PTFE

    4. One bottle of ceramic beads for grinding and one bottle of stainless steel beads.

    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.
