narc-1 columns are specifically formulated for rapid, reproducible extraction of Δ9 THC-carboxylic acid from urine using a unique, patented carboxy ester bonded phase. It has high selectivity and provides highly consistent recoveries without co-extracting many other commonly used drugs.
narc-1 and narc-2 columns can be used for many other important drug screening extractions such as opiates, LSD, phencyclidine, amine-based drugs, cocaine, and general screening.
