DB-5 ms EVDX columns provide consistent retention and peak shapes and are specially configured and tested for drugs of abuse confirmation.

Supplier: AGILENT HEWLETT PACKARD

These columns are not bonded or cross-linked, and are therefore useful for established methods that do not require the column to have cross-linked or bonded polymer phases. Because SE series columns are not bonded or cross-linked, solvent rinsing is not recommend.

Supplier: AGILENT HEWLETT PACKARD

These columns are ideal for the reproductible separation of proteins and peptides or other large molecules.

Supplier: AGILENT HEWLETT PACKARD

These HPLC columns are made with type A silica. They are useful for many applications of acidic or neutral compounds. These columns have a higher activity level and are therefore useful for separating isomers or other compounds where silanol activity enhances selectivity.

PVA coated capillaries contain a permanently adsorbed layer of polyvinyl alcohol. This coating minimises hydrophobic and electrostatic solute/wall interactions and eliminates electroosmotic flow (EOF). Using a proprietary deposition process, the PVA coating is stable over a wide pHrange, even under basic conditions from 2,5 to 9,5. This stability allows the use of many common CE buffers. Because the silica surface is covered, many proteins and amines can be analysed without the peak tailing found with uncoated capillaries. In addition, since EOF is eliminated, cumbersome washing procedures are unnecessary and migration time reproducibility may be improved.

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.
