This refurbished Whatman 78-40 TOC Gas Generator is in great shape. It has been tested at SpectraLab Scientific.
The 78-40 TOC Gas Generator produces carrier/combustion gas from an existing compressed air supply for TOC instruments, eliminating the need to purchase expensive, inconvenient, high pressure cylinders of oxygen, air or nitrogen.
The 78-40 utilizes catalytic oxidation and pressure swing adsorption technologies to remove hydrocarbons to 0.1 ppm (measured as methane), CO2 to 1 ppm and water vapour to 1 ppm (-73°C dewpoint).
The TOC Gas Generator eliminates all the inconvenience and cost of cylinder gas supplies and dependence on outside vendors. Uncontrollable vendor price increases, contract negotiations, long term commitments and cylinder rentals are no longer a concern. The TOC Gas Generator offers long term cost stability. The 78-40 is a complete system with carefully matched components engineered for easy installation, operation and long term reliability. Installation consists of connecting a standard compressed air line to the inlet and connecting the outlet to the TOC gas supply line. Plug the generator into a standard electrical wall outlet and within minutes high purity
carrier/combustion gas is supplied.
A 90-day warranty is included. Thanks for looking and we look forward to hearing from you!
