GOW-MAC Instrument Co. products

The Series 5900 Isothermal Gas Chromatograph features our patented Discharge Ionization Detector (DID) which detects trace gas impurities in the part per billion (ppb) range.  This second generation DID gas chromatograph features our patented detector, LCD touchscreen control, custom valve configurations, and a corrosion resistant option. Manufacturers, distributors, and users of specialty, electronic, and industrial bulk gases can rely on the Series 5900 for superior detection limits, reproducibility, and accuracy.

The Series 836 High Performance Gas Chromatograph combines the industry’s leading digital platform with GOW-MAC detector technology. This combination gives the analyst the tools to perform different levels of analysis on up to three different detectors. The Series 836 can have different combinations of the Discharge Ionization Detector (DID), Thermal Conductivity Detector (TCD), and Flame Ionization Detector (FID). The Series 836 can support up to eight valves, capillary, wide-bore capillary, or packed analytical columns. Electronic Pressure Controllers (EPC’s) can be installed along with numerous other options.

The Series 580 Isothermal Gas Chromatograph sets the standard for reliability in GC analysis. The Series 580 can be installed with either a single Thermal Conductivity Detector (TCD) or Flame Ionization Detector (FID). The Series 580 has a large oven capacity and can include optional custom valve configurations, heated valve oven, methanizer for the FID, and can accommodate packed or wide-bore capillary columns.

The Series 400 is a compact, affordable Isothermal Gas Chromatograph with a Thermal Conductivity Detector (TCD) designed to take the demands of the educational or quality control laboratory. The Series 400 comes with polar and non-polar analytical columns installed for experiments in the academic lab. It can also be customized with manual or automatic gas sample valves for use in the QC lab. A 400-P Prep version and 400-MGA Medical Gas Analysis version are also available.

The Series 2500 Total Hydrocarbon Analyzer is microprocessor-controlled designed to continuously measure concentrations of hydrocarbons. The Series 2500 utilizes a Flame Ionization Detector (FID) operating on the principle that the electrical conductivity of a gas is directly proportional to the concentration of charged particles within the gas. Designed to continuously measure and monitor concentrations of Hydrocarbons in a gas stream, it can also measure CO & CO2 using a methanizer. The instrument provides long term stability and accurate performance in a multitude of gas manufacturing facilities and laboratory applications.

The Series 5200 is equipped with a diffusion thermal conductivity detector (TCD). This detector is relatively insensitive to flow changes from 50 to 500 cm3/min. The Series 5200 analyzer interface is on its 7-inch touchscreen. The navigation of configuration pages is done with onscreen tabs, as the screen facilitates fast monitoring and reporting of data. Sample and reference gases are selected from menus in the mass flow controllers. Indicated flows therefore are true.The Series 5200 features three display modes: PPM, %, and PURITY %. The PPM mode (default) will display impurities in the PPM range. The % mode will display impurities in % concentration. The PURITY % mode will show the sample gas purity as 100% PURE and will decrease with the presence of impurities.

The Series 20-600 Portable Gas analyzer is designed for the quantitative measurement of binary gas mixes.  This rugged, portable, battery operated instrument is ideal for on-site gas measurement. It can be equipped with different sealed reference gases including helium for the airship industry.

The Model 21-080 Gas Leak Detector is portable, microprocessor controlled, and designed to detect gas leaks which have a different thermal conductivity than air. Designed with a micro thermistor, the 21-080 draws in ambient air as a reference gas for comparison to a gas drawn in through the sample probe. The intensity of the leak is indicated by both an LED display and audible alarm.
