High Sensitivity Gas Chromatograph System
Long-Term Stability with New Discharge Design
The architecture of the BID was designed such that the plasma generation zone is maintained at near room temperature. The metal electrodes are positioned where they do not contact directly with the plasma. This robust design requires no routine maintenance or consumables.
Evaluation of Long-Term Stability
A sensitivity fluctuation test was performed for operation times of 96, 2,688, and 3,240 hours. When relative intensities of 2,688 and 3,240 hours vs. peak intensity at 96 hours are calculated, the difference was negligible.
Repeatability of Trace Gas Analysis
A series of sample loop analyses was performed at 5 ppm concentration of each component. The calculated area repeatability showed RSD% of 0.84 – 1.80.
