Hawach QuEChERS Solutions
Package 1 QuEChERS extracting pesticide residues from plants
Extraction box: 50 ml centrifuge tube + AOAC/EN salt pack
2 kinds of buffer salts: General buffer salt for phase-separation and pH-adjustment;
Anhydrous magnesium sulfate completely separates water in the matrix from the acetonitrile extract.
Package 2 QuEChERS cleaning up the extracted mixture via absorption action
Purification box: 2 ml/15ml Purification tube with the adsorbent (PSA, GCB, C18, anhydrous magnesium sulfate) inside.
PSA can be used to remove polar interferences, such as adsorbed carbohydrates, organic acids, and pigments etc.
GCB adsorbs chlorophyll, mainly for high potency fat and pigment fruits and vegetables, such as eggplant, green vegetables, carrots etc.
C18 removes non-polar interferences, for example, avocado.
Anhydrous magnesium sulfate removes moisture from the substrate and is widely used in various foods.
Package 3 QuEChERS extracting and purifying the pesticide residues.
Extraction tube 1EA + Purification tube 2EA.
Package 4 Prevents local heat dissipation caused by salt agglomeration; makes the pH of the whole system more uniform; thus making the extraction better and saving extraction time.
Ceramic homogenizer 2ml/15ml/50ml three specifications
Easy, straightforward and almost can start without any training. Except for those 4 options, standard adsorbents, salt packs, ceramic homogenizers, etc. can also be customized or purchased separately.
