MIDAC’s open path Fourier transform infrared spectrometers can measure extreme path lengths, which enables users to analyze methane, carbon dioxide and nitrous oxide with up to single-digit ppb detection limits. A 60-inch source array sends an infrared beam to a receiving telescope that can be more than a kilometer away; the spectrometer measures the air between them.
FTIR Gas Analysis System
The Midac AM System provides a versatile, open path, FTIR gas analysis system designed to detect, identify, and measure compounds simultaneously and within seconds. Analysis is performed on-site through a continuous sampling path of up to 1,000 meters. The system provides continuous, unattended, near real-time detection at parts per billion to percent levels for hundreds of chemicals. Each system includes a rugged, sealed interferometer equipped with a choice of beam splitters and detectors.
