Whatman 78-40 TOC Gas Generator
ITEM: 32307 In Stock
The Whatman 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 Whatman 78-40 Gas Generator utilizes catalytic oxidation and pressure swing adsorption technologies to remove hydrocarbons to 0.1 ppm (measured as methane), CO2 to 1 ppm and water vapor to 1 ppm (-73°C dewpoint). The unit eliminates all the inconvenience and cost of cylinder gas supplies and outside costs.
The Whatman 78-40 TOC Gas Generator 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.
- Replaces high pressure oxygen or nitrogen gas cylinders with hydrocarbon-free, CO2-free compressed gas for TOC analyzers.
- Ensures consistent, reliable, TOC operation and significantly reduces instrument service and maintenance costs.
- Compact design frees up valuable laboratory floor space.
- Purity meets or exceeds all TOC manufacturers' gas purity requirements.
