The main analytical laboratory and corporate offices are located in West Columbia, SC near the
intersection of Interstates 26 and 77 in a business park. This is approximately 5 miles west of
downtown Columbia and approximately 8 miles from the Columbia Metropolitan Airport. The
15,000 square foot building was designed and constructed in 1992, and offers many state-of-the-
art technological features.
The building's unique computer controlled closed system (chiller/boiler) seven-module cooling
and heating system maintains negative, atmospheric, or positive pressure in seven general work
areas. This system has been balanced with the laboratory's fume hoods and outside air to
provide the appropriate pressure to each work area.
The volatile organic analyses area operates under positive pressure to prevent the influx of
airborne contamination. This spacious laboratory is located in the opposite corner of the building
from the extractions laboratory.
The semivolatile organics analyses area operates under negative pressure. A hydrogen and
zero-air generator supply uninterrupted high purity gases to the GCs.
The organic extractions area operates under negative pressure to prevent the migration of
airborne contamination into other areas. A point of use solvent delivery system provides
methylene chloride dispensing. This system eliminates the disposal of over 700 glass bottles and
packaging materials per year, reduces labor costs, and significantly reduces our analysts
exposure to methylene chloride vapors. A 66-station continuous liquid-liquid extraction system is
used for most aqueous samples.
The metals analysis area operates under positive pressure. A 900-gallon liquid argon tank
provides an uninterrupted supply of argon for the instrumentation. The metals preparation area is
equipped with clean room polypropylene casework and an 8-foot polypropylene hood. Digestions
are performed in hot blocks using disposable digestion tubes. The metals preparation lab as well
as the metals analysis labs have clean room ceilings.
The inorganic non-metals area operates under atmospheric to negative pressures. This area
consists of 4 rooms. The largest room contains all the instrumentation. The other 3 rooms are
used for compatible preparations or analyses. All digestions and distillations are performed using
Other facility features include secure keypad entry into building, data review/processing areas
separate from the preparation and analysis laboratories, an efficient sample receiving area, three
walk-in coolers for proper sample storage, and a centralized and secure LIMS computer area.
