Systems and methods for pressure differential molecular spectroscopy of compressible fluids |
| abstract |
Described herein is a spectroscopic system and method for measuring and monitoring the chemical composition and/or impurity content of a sample or sample stream using absorption light spectroscopy. Specifically, in certain embodiments, this invention relates to the use of sample pressure variation to alter the magnitude of the absorption spectrum (e.g., wavelengthdependent signal) received for the sample, thereby obviating the need for a reference or zero sample. Rather than use a reference or zero sample, embodiments described herein obtain a spectrum/signal from a sample-containing cell at both a first pressure and a second (different) pressure. |
