Services - Analytical Chemistry (Analytical Capabilities)

For over 25 years, CompuChem has been the nation's leading provider of Contract Lab Program (CLP) and CLP-like data. Headquartered in Cary, NC, CompuChem has an experienced staff, a broad range of analytical services, and an unfailing commitment to quality and method compliance. The company maintains a wide variety 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 tissue/organs/oil, bird tissue/organs, concrete chips, heavy oil, and ceiling tiles. Our environmental testing laboratory has analyzed tens of thousands of samples with sludge, sediment, soil, water, biota, and waste matrices.

CompuChem operates one of the largest single-site environmental analytical instrumentation facilities in the country. CompuChem 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.
