Educational Isothermal Gas Chromatograph

Efficiently perform chromatographic separations and produce chromatograms with this rugged instrument. This impressive tool boasts dual injection ports, a single thermal conductivity detector, and independent control for injection ports, column oven, and detector. The platinum temperature sensors provide superior reproducibility of oven temperatures and can be operated at temperatures from ambient to 300°C. Gas samples offered include six, eight, and ten-port valves. The valves are all equipped with 2.0mL sample loops as standard, and up to two externally mounted gas sample valves can be designed into the flow system. This model also includes unique safety features with upper limit temperature controls in the event of a malfunction, filament protection circuit, and the column will automatically shut down if the temperature exceeds the setpoint by more than 30°C. The operating controls consist of a 12-step binary attenuator, 31.2 digit LED digital meter for temperature and current readout, zero control, bridge current control, three temperature controls, polarity switch, and dc power switch. Includes two analytical columns: 4' x 1.8" st. st. 20% DC 200 on Chromosorb P-AW, 4' x 1.8" st. st. 20% Carbowax 20Mon Chromosob P-AW.
