| S | 5000.0000 (Minimum concentration detected) | 869.4600 | N/A | Univariate Calibration | 5000.0000-200000.0000 | The 869.46nm peak was chosen as their detector did not have good sensitivity and the stronger 921.28/922.81/92..75nm triplet. Data collected under He atmosphere. Signal strength dependent on He pressure, with best results at 100-200mbar. No ratioing was performed, as there were no suitable peaks in the available spectrum around the S peak at 869.46nm. |
