Bed Composition

LipidX D is a mixed mode material that removes lipids, pigments from solvent extract

CarbonX BOS material is a mixed mode material that retains polar hydrophilic compounds and acids at pH > 4.  We recommend this

CarbonX Plus is our premier material for QuEChERS. It does not have lewis acid base interactions like the lipid removal material has.   

CarbonX FOS is carbon on Florisil. It is used for recovery of chlorinated analytes and dioxin methods.

C18 that has been endcapped retains lipids via hydophobic interactions.  However, C18 does not retain lipids well with pure ACN and a water modifier to the eluent or sample is recommended.

Other polar components are removed via PSA interaction.  If buffered at pH > 6, the PSA will retain acids.    Below the pKA, these acids are protonated and there is no ion exchange interaction.
