SPE Plates
Functional groups, such as octyl (C8) and octadecyl (C18), can be bonded to the silica surface to provide non polar interactions. Each of these sorbents exhibits unique properties of retention and selectivity for a particular analyte. The choice of which sorbent is best for a particular method will be influenced by the percent recovery of analyte from the sample matrix and the cleanliness of the resulting chromatography.

This mixed phase chemistry, in which two primary modes of attraction are present, allows for a more efficient and selective extraction compared to traditional reversed phase techniques. Neutral and ionized analytes can be simultaneously extracted from a complex mixture and eluted as separate fractions. A mixed phase sorbent offers the following advantages: Eluting acidic and neutral analytes separately from basic analyt…
This chemistry promotes high retention of a wide range of analytes, reducing method development time and facilitating a generic approach to sample preparation.
