MAX-iR FTIR Gas Analyzer

The Thermo Scientific™ MAX-iR™ FTIR Gas Analyzer has been engineered to meet the most demanding standards for in-line process, batch sampling, gas purity/certification, emissions testing, and ambient air monitoring. Combined withThermo Scientific™ StarBoost™ Enhanced Optical Technology, the MAX-iR™ analyzer enables users to achieve single-digit ppb detection limits for many applications. For ultra-high purity bulk gas applications, the detection limits can be reduced to mid ppt, making the MAX-iR analyzer one of the most sensitive FTIR gas analyzers ever produced!

The MAX-iR analyzer is controlled by high-performance analytical software specifically developed for real-time process and CEM environments. Fully automated method control, DCS data output, alarm controls, remote access, and reporting tools are all designed to maximize productivity without human interaction. Combined with our standard application-specific multi-channel gas handling panels, the MAX-iR easily goes from being a stand-alone analyzer to a fully automated solution.

Let the MAX-iR analyzer reinvent how to solve your most demanding challenges in process gas analysis.

Variety of Configurations

The MAX-iR gas analyzer is based on a tiny, rugged, high-throughput interferometer with an embedded 24-bit analog to digital (ADC) detector modules that provide excellent signal-to-noise without the use of liquid nitrogen. A long-life vertical cavity surface-emitting laser (VCSEL) diode and a silicon carbide (SiC) IR source have boosted the analyzer’s longevity and dependability.

For the most demanding certification operations, incorporated temperature and pressure sensors give enhanced accuracy. Lastly, the analyzer’s dual-level vibrational dampening enables it to function even under harsh field conditions.

The MAX-iR analyzer includes a deuterated triglycine sulfate (DTGS) detector as standard. Users can choose between indium arsenide (InAs) and mercury-cadmium-telluride (MCT) detectors with the additional StarBoost technology.

Thermo Scientific^TM MAX-Acquisition^TM Automation Software and MAX-Analytics^TM Software come as standard on all systems, providing industry-leading analytics, factory integration tools, elevated compound identification, and measurement precision without the need for calibration.
