The TOC 1000 uses new PSA and catalytic cracking technology to provide clean, dry CO2 and hydrocarbon free gas for TOC to use as combustion gas. The TOC 1000 is a small, compact unit that provides continuous carrier/combustion gas for TC, IC, TOC and NPOC equipment. TOC 1000 can meet the combustion gas requirements of all TOC analyzers. A Peak TOC 1000 gas generator with a large flow rate of 1000cc/min can meet the gas requirements of more than 5 sets of TOC. TOC 1000 gas generator does not have built-in air compressor, runs silently, and needs to be equipped with external air source.
