Air-Monitoring System
The open-path Fourier transform infrared (FTIR) air-monitoring system simultaneously detects, identifies and measures a wide range of contaminants at levels from percent to parts per billion. Each system includes an interferometer that is equipped with user-selected beamsplitters and detectors. The analyzer is coupled to a control PC via standard ribbon cable or long-range fiber optic link. A continuous sampling path up to 1,000 m long is standard; for extended sample paths, the FTIR can be mounted to a rugged 10-in. Newtonian telescope supported by a tripod. A high-energy infrared source module on the opposite end of the sample path completes the system. Weighing 40 lb and measuring 8 in. W × 14 in. D × 8 in. H, the compact interferometer module is easy to transport and can be powered by a 12-V car battery. An optional lightweight sheetmetal version of the FTIR is available with a compact 3-in. telescope. The system is suitable for industrial stack monitoring, fenceline monitoring, hazardous event response, analysis of chemical warfare agents on the battlefield, and environmental research (such as volcanic gas analysis).

FTIR spectroscopy gas-analysis system
This open-path Fourier transform infrared (FTIR) spectroscopy gas-analysis system monitors air to simultaneously detect, identify and measure a wide range of compounds.†Analysis is performed onsite through a continuous sampling path of up to 1,000 m. The analyzer is coupled to a control PC via a standard ribbon cable or a long-range fiber-optic link. For extended sample paths, the analyzer can be mounted to a 10-in. Newtonian telescope with a tripod. A high-energy infrared source module is located on the opposite end of the sample path. Each system has a rugged, sealed interferometer equipped with beamsplitters and detectors. Weighing approximately 40 lb and measuring 8 in. wide by 14 in. deep by 8 in. high, this compact interferometer module can be powered by a 12-V car battery for easy transport

Titan-OL (On-Line) system
The Titan-OL (On-Line) system provides real-time extractive-gas-phase analysis for online and continuous multi-point analysis. It includes a rugged, industrial Fourier transform infrared (FTIR) spectrometer, gas cell(s), sample manifold, valve-control electronics, and software. The hardware is encased in a NEMA-rated enclosure or in a standard industrial rack-mount cabinet. The manufacturer’s exclusive fiber-optic distribution electronics provide a single hub for temperature, pressure, mass flow, external alarm, and optical switching signals. The system can accommodate up to four 12-port manifolds for a total of 48 sample, purge and calibration lines, with communication between the hub and control computer via fast, stable fiber-optic cable. Titan-OL systems use dual analog-to-digital converter (ADC) architecture and advanced mirror drive control for increased sensitivity and very low detection levels for a variety of compounds. Custom gas cells are corrosion-resistant and are available with path lengths from 0.01 m to 30 m. The systems can operate at temperatures from ambient to 240ºC, allowing moist sample streams to be analyzed without condensation. The included AutoQuant Pro software package handles method calibration, data collection, trend analysis charting, manifold control, and integration of alarm and control functions with plant process hardware and software

Titan industrial Fourier transform infrared (FTIR) spectroscopy systems
 Titan industrial Fourier transform infrared (FTIR) spectroscopy systems provide real-time, multi-component extractive gas-phase analysis for such applications as industrial hygiene, composite epoxy materials (CEM), process optimization/control, specialty gas quality-control, and research. They are packaged with externally mounted, corrosion-resistant gas cells, whose pathlengths range from 1 cm to 60 m. Thermal isolation enables operation at temperatures from ambient to 240_C, allowing moist sample streams to be analyzed without condensation. Combined with customized infrared (IR) detectors for ultimate sensitivity, these systems can achieve low-ppb detection levels for most compounds of interest. They can be equipped with optical switching between sample cells to accommodate the need for different sample pathlengths or to prevent cross-contamination.
