Solid-phase extraction (SPE) is a sample preparation process by which compounds that are dissolved or suspended in a liquid mixture are separated from other compounds in the mixture according to their physical and chemical properties. Analytical laboratories use solid phase extraction to concentrate and purify samples for analysis. Solid phase extraction can be used to isolate analytes of interest from a wide variety of matrices, including urine, blood, water, beverages, soil, and animal tissue


RIDA® C18 column

Art. No.: R2002

Intended use:

The solid phase extraction (SPE) with RIDA® C18 columns is an efficient technique for a fast and selective sample preparation, especially for the RIDASCREEN® anabolic- and hormone enzyme immunoassays.

General information:

A solid phase extraction procedure normally consists of 5 steps:

− sample pre-treatment (extraction and conditioning of the extract)
− column solvation and pre-equilibration
− sample application
− elution of interfering matrix components / rinsing of the column
− elution of the analyte

Art. No. R2002
Test format 100 x C18 columns (100 mg/ml column reservoir) with 100 mg end-capped sorbent (octadecyl sorbent)
