Our Laboratory
Our instrumentation consists of the following items:
Analytical:
High Performance Liquid Chromatograph with Mass Selective Detector. Agilent Technologies 1100 Series LC-MSD.
Agilent Technologies 6890 Series gas chromatograph coupled with a 5973 mass selective detector (capable of fragmentation by both electron impact and chemical ionization) and G2397A micro-electron capture detectors.
Agilent Technologies 6890 Series gas chromatograph coupled with a P.S. Analytical atomic florescence detector for methyl and ethyl mercury determinations.
Nippon Instruments Model SP-3D for total mercury determinations.
Tekran Model 2620 analyzer for total mercury, and a Tekran mercury vapor analyzer Model 2537A (not shown).
High Performance Liquid Chromatography with photo Diode Array Detector (below). Agilent Technologies 1100 Series HPLC.
Digital Gamma Ray Spectrometer. Used for radiometrically dating lake sediments and peat by the Uranium- 238 decay series and Cesium-137.
Our sample extraction facility consists of the following items:
Accelerated Solvent Extraction (below), Soxhlet, microwave and various other manual methods. Our typical samples include: air, water, soil, lake sediments, animal and plant tissues.
We have a variety of instruments to assist in the “clean-up” and preparation of samples, such as HPLC, and Automated Gel Permeation Chromatography (below), as well as many other manual techniques which involve silica gel, Florisil, XAD, and Solid Phase Extraction.
There is a wide range of techniques available for concentrating sample extracts. These include:
Distillation units
TurboVap II
SpeedVac
