Description of Major Equipment in BCH Laboratory

1. Capillary Electrophoresis System, MDQ (Beckman Coulter P/ACE)

BCH equipped with the Beckman P/ACE MDQ CE System with Diode Array detector from 90 - 600 nm and 200, 214, 254, 280 nm standard filter. The P/ACE Series are automated, programmable capillary electrophoresis systems designed to perform fast separations from complex samples. Separations occur in a capillary which is housed in an interchangeable cartridge with circulating liquid coolant for efficient temperature control. This finely regulated temperature control allows the use of high-ionic-strength buffers and large-bore capillaries necessary for analyzing difficult samples

5. Liquid Chromatography-Mass Spectrometers (LC/MS/MS)
The Liquid Chromatograph Triple- Quadrupole Mass Spectrometer is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography with the mass analysis capabilities of mass spectrometry. LC-MS is a powerful technique used for many applications which has very high sensitivity and specificity. It is also used for elucidating the chemical structures of molecules, such as peptides and other chemical compound.

6. High Temperature Gel Permeation Chromatograph (Varian PL-GPC 220)

GPC/ SEC is the technique of choice for rapid and reliable characterization of polymer molecular weight and molecular weight distribution. This PL-GPC 220 integrated GPC/SEC system, coupled with RI, UV and Viscosity detectors, is designed to run all polymer, solvent and temperature combinations, with full automation, from 30 to 220oC.

10. Flow Injection Analyzer (Lachat QuikChem 8500)

The FIA components consist of auto sampler, reagent pump, system unit, a windows compatible computer with Omnion software and a printer. Four channels are configured to analyze with photometric detection. The system is ideal for the measurement of ammonia, nitrate/nitrite, phosphate, Total Kjeldahl Nitrogen (TKN), Total Phosphate (TP), and Formaldehyde in water, brackish water, and soil and food sample.
