STATE-OF-THE-ART INSTRUMENTATION

ICP-MS

Our laboratory's state-of-the-art instrumentation includes a Hewlett Packard 4500 Inductively Coupled Plasma Mass Spectrometer (ICPMS) or a Perkin Elmer 6100 DRC ICPMS for analyzing trace elements in environmental samples.

We employ a Closed-Vessel Microwave Digestion System for Sample digestion--a sealed system of Teflon vessels which virtually eliminates potential contamination of your samples.

Sample analysis for Trace Elements uses Inductively Coupled Plasma Mass Spectrometry (ICPMS) capable of measuring 71 target analytes simultaneously.

Using our Dynamic Reaction Cell, we are able to analyze for the more difficult elements such as Calcium, Selenium, Arsenic, Potassium, Sodium, and may more.

GCMS

Sample analysis uses Capillary Gas Chromatography/Mass Spectrometry (GCMS). For PCBs, state-of-the-art congener-specific analysis is our specialty. Using this technique, we can fingerprint your sample and provide more accurate quantitation using congeners or we can use the Aroclor-based technique. We also specialize in the National Oceanic and Atmospheric Administration's (NOAA) National Status and Trends list of analytes, PAHs and their alkyl homologies, sterols, linear alkyl benzenes and custom analytes to meet your needs.

ELEMENTAL ANALYSIS

For elemental analysis we have a Carlo Erba Elemental Analyzer. This technique uses combustion to determine the Total Organic Carbon and Total Nitrogen content of your samples. Using our spectrophotometer we can also analyze your samples for Ammonia, Nitrate, Nitrite, Phosphate, and many other nutrients.
