Rosemount™ 1500XA Natural Gas Chromatograph
rosemount 1500xa process gas chromatograph
Emerson Process Management offers a complete line of gas chromatographs specifically designed for process applications.
The 1500XA process gas chromatograph combines the proven analytical components of the field-mounted GCs with the larger oven capacity of a traditional air-bath oven design. The result is maximum analyzer reliability and analytical flexibility in one package.
