FEATURED PRODUCT: Model 322 LOW COST, COMPACT LAB GC
We have been involved in the laboratory GC market since 1976 when Jack Driscoll introduced the gas chromatography-based photoionization detector as an OEM product. Our first lab GC product line was brought to manufacture in 1984: the Model 300 Series compact lab GC's (Model 301/321).
The 300 series were designed with a small footprint and ideal for dedicated applications. We still service and support these rugged systems pictured below that were produced in the early 1990's. Click here to read the blog post about this particular application aboard the Research Vessel Knorr.
Our replacement Model 322 is easy to use with included Peakworks software accessed via USB port connected to a laptop or desktop.
Model 322 SPECIFICATIONS Detectors: Choose up to two - Photoionization detector (PID), Flame ionization detector (FID), Thermal conductivity detector (TCD), Flame photometric detector (FPD), Far UV absorbance (FUV) detector, Catalytic combustion detector (CCD)
- Species measured:
- PID & FID: Organics (VOCs by PID or FID) and inorganic species (H2S, NH3, AsH3... ) that can be ionized by the PID lamp (9.5, 10.6 or 11.7 eV)
- TCD: Universal detector- fixed gases (O2, N2, CO...), organic and inorganic compounds, very sensitive for H2, He, Xe
- FPD: Selective response for S or P compounds
- Far UV: Nearly universal response for organic and inorganic compounds
- CCD: Combustible compounds such as hydrocarbons
- Detection Limit:
- PID- 0.5 ppb benzene
