Thermo Fisher MAX-iR FTIR Gas Analyzer

Overview

The Thermo Fisher MAX-iR FTIR Gas Analyzer is a Fourier Transform Infrared gas analysis instrument engineered for in-line process monitoring, gas purity certification, and continuous emissions monitoring, delivering real-time multi-gas analysis with a response time between one second and one minute. Combined with Thermo Fisher’s optional StarBoost optical enhancement technology, the MAX-iR reaches single-digit ppb detection limits, with mid-ppt performance achievable in ultra-high-purity bulk gas applications, offering an alternative to gas chromatography (GC), mass spectrometry (MS), or cavity ring-down spectroscopy (CRDS) systems that are often slower and more costly to operate.

As an experienced supply partner for Thermo Fisher Scientific instrumentation in the region, Seven Star LLC supplies the Thermo Fisher MAX-iR FTIR Gas Analyzer to industrial plants, gas producers, and environmental testing laboratories across Oman and the wider GCC, with technical application support and support with selection.

Operating Principle

The Thermo Fisher MAX-iR FTIR Gas Analyzer works by passing infrared light through a sample gas contained in a 10-meter high-throughput multipass gas cell, and measuring how much light is absorbed at specific wavelengths characteristic of each target gas molecule’s vibrational modes. A compact, rugged interferometer with 1–32 cm¹ spectral resolution generates the interferogram, which is converted through Fourier Transform mathematics into a spectrum that reveals the identity and concentration of each gas species present, all without consuming any reagents or calibration gases during normal operation.

A long-life vertical cavity surface emitting laser (VCSEL) diode and silicon carbide (SiC) infrared source, both rated for a 10-year service life, keep the optical system stable over extended continuous operation, while non-hygroscopic optics eliminate the need for a dry air or nitrogen purge in most applications. The practical consequence for a plant or laboratory operator is a gas analyzer that delivers laboratory-grade quantitative accuracy continuously on the process line, without the sample-preparation delay or consumable costs associated with GC or wet-chemistry methods.

Engineering Design of Thermo Fisher MAX-iR FTIR Gas Analyzer

The Thermo Fisher MAX-iR FTIR Gas Analyzer is built into a rugged 5U, 19-inch rack-mount enclosure weighing approximately 75 lbs, with dual-level vibrational dampening that allows the interferometer to maintain measurement stability even when installed in mechanically noisy field environments near compressors, pumps, or rotating process equipment. Integrated temperature and pressure sensors continuously correct spectral readings for ambient variation, which is particularly important for demanding gas certification applications where measurement traceability must be defensible.

Sample gas connects through a single 1/4-inch Swagelok fitting, simplifying installation into existing sample conditioning systems, and the analyzer includes an optional nitrogen purge port for applications requiring additional optical protection. The standard deuterated triglycine sulfate (DTGS) detector can be upgraded to indium arsenide (InAs) or mercury-cadmium-telluride (MCT) detectors when paired with the StarBoost Technology option, and all systems ship with the MAX-Analytical STANDARD Software Suite for FTIR configuration, real-time quantitative analysis, and Modbus TCP/IP communications back to a plant historian or control system.

Key Features

The Thermo Fisher MAX-iR FTIR Gas Analyzer combines a rugged optical platform with long-life components to deliver dependable continuous gas analysis in demanding industrial settings. Its core features include:

• Real-time gas analysis with response times from 1 second to 1 minute depending on configuration.
• Single-digit ppb to tens of ppt detection limits achievable with the optional StarBoost optical enhancement technology.
• 1–32 cm¹ resolution FTIR spectrometer with a 10-meter high-throughput multipass gas cell.
• Long-life VCSEL diode laser and SiC infrared source, each rated for a 10-year operating lifetime.
• Non-hygroscopic optics that eliminate the need for a continuous purge in most installations.
• Integrated temperature and pressure sensors for measurement precision in demanding certification applications.
• Dual-level vibrational dampening for stable operation in mechanically active field environments.
• Modbus TCP/IP communications and MAX-Analytical STANDARD Software Suite for real-time quantitative analysis and factory integration.

Industrial Applications

The Thermo Fisher MAX-iR FTIR Gas Analyzer is used for in-line process monitoring, gas purity analysis, and continuous emissions monitoring (CEM) at refineries, gas processing plants, and power generation facilities across the Sultanate of Oman, where accurate, real-time gas composition data supports both process optimization and environmental compliance reporting. In the industrial zones around Sohar and Salalah, plant engineers deploy the MAX-iR for stationary source testing on turbines, reciprocating internal combustion engines (RICE), and cement kilns, where continuous multi-gas monitoring is required to demonstrate compliance with emissions limits.

Backed by manufacturer datasheet documentation, Seven Star LLC distributes and supports the MAX-iR FTIR Gas Analyzer for gas certification laboratories, LNG and petrochemical facilities, and ambient air quality monitoring programs across the region, where high-purity gas verification and leak detection are routine operational requirements. The analyzer’s compact rack-mount format and non-hygroscopic optics make it well suited to the space-constrained analyzer shelters common on regional process and metering skids.
