Introduction to Gas Phase FTIR Spectroscopy

such as gas cell pathlength and spectral resolution, FTIR spectroscopy can analyze gases at wildly contrasting concentrations. FTIR analysis of combustion samples, exhaust analysis for example, can measure CO 2 values at 25%, with NO values down to 1 ppm. Detection levels of low partsperbillion of contaminants in highpurity gas samples can be

EnviroAnalytical: FTIR Analyzers

These products are designed to measure: CO, CO2, CH4, C3H8, NO, NO2, N2O, NH3, NMHC, NOX, SF6, SO2, THC. FTIR Spectroscopy is an analytical technique which measures the infrared intensity versus wavelength (wave number) of light. The FTIR Spectrometer obtains infrared spectra by collection an interferogram of a sample signal with an interferometer.
