Product features and applications
♦ Rapid analysis; complete analysis of all C1-C6 components within 2 minutes.
♦ High sensitivity, MEMS process TCD, can test samples with concentrations as low as <1 ppm.
♦ Active sampling allows for direct analysis of samples under normal or negative pressure without the need for external pressurization.
♦ Extremely flexible, it can be used for laboratory gas analysis or on-site testing of parallel chromatography; with a single injection, the sample can enter up to four modules simultaneously.
♦ It consumes less power, with gas and electricity costs less than 1/10 of conventional chromatography.
♦ Built-in industrial touchscreen allows for direct viewing of graphs and results.
♦ Linux operating system, stable and reliable
