کارتریج CLEAN SCREEN FASt THC

CLEAN SCREEN FASt® THC employs a process that uses positive pressure, solid phase sorbent bed and small pore frits to quickly and efficiently prepare urine samples for LC/MS analysis. The methodology eliminates timely centrifugation, reduces matrix suppression effects and removes particulates greater than 1 µm. Samples can be diluted at a ratio as low as 1:1, which is useful for detecting analytes at very low concentrations.
