Total Hydrocarbon Analyzer (THA) - Series 9000 from Baseline

The Baseline® Series 9000 hydrocarbon analyzer has a dynamic range from less than 10ppb on the low range version and up to 100% as methane on the high range version. The analyzer is provided with a combination of analog, digital and logic output functions.

The detector in the Series 9000 is a flame ionization detector (FID) which is coupled with FlowGuard electronic control for supplying a small portion of the sample gas to the detector flame. During the combustion process, organic or hydrocarbon-based gases in the sample are ionized and then detected by the analyzer and recorded as a concentration.

It is possible to configure the Series 9000 with internal parts to suit the single or multi-point analysis of non-condensing gas samples. The automatic calibration function improves the long-term analytical stability of the tool, thereby ensuring that the tool has superior automation, performance and configurability.
