Services - Analytical Chemistry (Analytical Capabilities)
CompuChem has been the nation's leading provider of Contract Lab Program (CLP) services
and CLP-like data since 1981. Headquartered in Cary, NC, we have an experienced
staff, a broad range of analytical services, and an unfailing commitment to quality
and method compliance. The company maintains a number of certifications and capabilities
and is actively involved in both the Federal Services and Commercial environmental
sectors.
The company has analyzed samples of every conceivable type of matrix, including,
fish, crab, oyster, worm tissue/organs/oil, bird tissue/organs, concrete/wood chips,
heavy oil, and ceiling tiles. Our environmental testing laboratory has analyzed
hundreds of thousands of samples with sludge, sediment, soil, water, biota, and
waste matrices.
We continue to operate one of the largest single-site environmental analytical instrumentation
facilities in the country. The company is able to analyze large delivery groups
of samples for a wide variety of parameters. This large, diverse analytical capacity
at one site avoids the potential confusion and error that could be introduced by
dividing large sample batches between facilities located at separate locations.
CompuChem consists of several separate environmental testing laboratory areas that
prepare and analyze environmental samples for the presence of organic and inorganic
contaminants. Written standard operating procedures (SOPs) that comply with published
analytical methods are in place in each laboratory area at CompuChem. These procedures
are derived from methods published in the following documents:

Laboratory Information Management System (LIMS)
CompuChem's Management Information System utilizes a variety of MIS technologies
to support Organic and Inorganic sample analysis, data processing, and reporting.
The LIMS is the backbone of the company's infrastructure, as it manages all sample
receiving and sample tracking information. The organic laboratories utilize separate
data acquisition software to automatically transfer data to one of three UNIX™ systems.
The inorganics laboratories also use separate data acquisition software, while data
processing and reporting are performed on a Windows NT™ platform. This infrastructure
is protected by a number of resources, including a Firewall, Raid 5 redundancy,
TCP/IP protocols, an Uninterruptible Power Supply, an aggressive backup strategy,
and password protection. All of these systems contribute to the successful operation
of the MIS department. CompuChem purchased the LabVantage™ Solutions Seedpak V 3.98.1
LIMS in the fall of 1999. The LIMS runs on a UNIX™ operating system and is driven
by a powerful Oracle™ database. The system uses dual processors combined with Raid
5 technology to provide enhanced performance and data redundancy. In addition to
Raid 5, CompuChem also employs a backup strategy for data protection. Organic data
acquisition is accomplished by dedicated computer systems, which use either EZ Chrom™
or Chemstation™ software. Upon completion of each analysis, data are immediately
transferred to a UNIX™ server for processing. ThruPut™ software is used for data
processing, which in turn produces hard copy forms along with what is referred to
as a CompuChem format or Superset electronic file. Inorganic data acquisition is
also accomplished through the utilization of dedicated computer systems through
a variety of serial and network links. Data are processed using either Metals Analytical
Review and Reporting System™ (MARRS) or General Chemistry Analytical Review and
Reporting System™ (GARRS) software. Both MARRS and GARRS contain impressive capabilities
that include the importation of data from a variety of different instruments as
well as the ability to retrieve sample information from the LIMS. These capabilities
allow personnel to review data effectively and accurately generate forms and a superset
electronic file. Programmers may utilize a variety of resources to generate Electronic
Data Deliverables. Both organic and inorganic software generate a master electronic
file. This file contains all the information about the sample analysis. These files
can be queried from the LIMS to allow the retrieval of any sample receipt information.
By utilizing the master electronic file and the LIMS, our personnel can construct
customized reporting formats.CompuChem has taken a forceful approach in order to
ensure network and data security. The network is protected from the Internet community
by an advanced checkpoint firewall. The firewall inspects every packet that tries
to enter the network and denies any effort to breech it. All UNIX™ and Windows NT™
servers are password protected and utilize the TCP/IP protocol. All systems are
backed up regularly and are protected by our 300 kV uninterruptible power supply
(UPS). This solid state, on-line system filters power entering the building, providing
electricity free of voltage spikes or drops to these critical electronic components.
A battery back-up system provides power for up to two hours in the event of a complete
power failure.
