Detection limits in the VUV and the UV/Vis/IR are compared in this paper. The UV/Vis/IR results are described here. Only a Photomultiplier was used here, with the spectrum built up by stepping the monochromator. |
Element | Detection Limit (ppm) | Wavelength (nm) | Other Wavelengths (nm) | Calibration Method | Calibration Range (ppm) | Notes |
---|---|---|---|---|---|---|
Br | 500.0000 (Stated) | 130.9900 | 148.85nm, 153.17nm, 157.48nm, 163.34nm, 131.67/131.74/131.77nm | Univariate Calibration | -10.0000--10.0000 | Experiments were performed in both 2l/min Ar flow and a static atmosphere of 1000mbar. Under the gas flow several peaks were detected which were apparent in the static atmosphere. The build up of molecular oxygen in the chamber was thought to be the cause of the difference. Ratioing the 130.99 Br I peak to C I at 193.09nm improved the performance. |
