Hardware, Software, and Operational Procedures for an Extractive FT-IR Air Monitoring System

摘要

The report provides a general background for extractive sampling with FT-IR spectroscopy. The report also documents the procedures necessary to validate the performance of an FT-IR spectrometer used in an extractive sampling application. The design, fabrication, and implementation of an extractive FT-IR system are demonstrated. Alignment methods for a 10-m optical gas cell and FT-IR spectrometer is furnished in a step-by-step procedure list. Creation of reference spectra is shown for a target analyte of ethanol at 200 0C. Appendixes contain details on (1) FT-IR spectrometer hardware, (2) sampling protocols for extractive FT-IR spectroscopy, and (3) baseline spectra of ethanol and ethylene simulants.
