QuEChERS dispersive kits

Catalog Number: (HEWL5982-5258CH)
Supplier: Agilent
Description: Step 2: Dispersive SPE cleanup
Select the dispersive SPE kit suited to the type of food being analysed and the method you are following. In this step, an aliquot of the sample extract from step one (see QuEChERS extraction kits) is added to a 2 or 15 ml centrifuge tube containing a small amount of SPE sorbent and MgSO₄. The sorbent will pull out interfering matrix materials from the sample, while the MgSO₄ helps remove excess water and improve analyte partitioning.

Sample loops for Rheodyne® valves

Catalog Number: (554-1051)
Supplier: VICI JOUR RESEARCH
Description: These PEEK sample loops contain no metals or other extractable compounds. Therefore, no foreign materials will be introduced into the system. Softener free PE caps are used to avoid the contamination of the tubing. Particularly suited for separations involving proteins, peptides, nucleic acids or other samples of biological origin as well as in IC systems where metal traces may interact with ionic samples or release transition metals that may deactivate ion exchange columns.
