Filter and Shoot

The FASt® column is a novel approach to improved sample preparation for LC/MS analysis. The column employs a one step process to prepare urine samples for analysis of multiple drugs and metabolites. By quickly and efficiently reducing the amount of unwanted matrix (through sorbent adsorption) and particulates (filtering through special frits) in the final sample, the analysis can proceed with less chance of matrix suppression and LC column clogging.
