The organic department occupies 3,500 sq. ft. of the 10,000 sq. ft. at Sierra Laboratories.  We utilize Hewlett Packard instrumentation almost exclusively with seven (7) GC’s and two (2) GC/MS.  All instrumentation is automated and well maintained on a daily basis.  The extraction lab is equipped with the latest equipment.  We are capable of performing separatory-funnel, liquid-liquid continuous, sonication and soxhlet extractions.

We also use liquid-solid extraction for drinking water methods.  We are very flexible in meeting the needs of the client, from immediate results to confirmation of MTBE by GC/MS and identification of unknown compounds by GC/MS.
