atmosFIRt is the latest generation of FTIR gas analyser technology from Protea in a portable or mobile form. The atmosFIR system improves upon previous FTIR technology and represents one of the most cost-effective and flexible analytical products on the market today. At the heart of atmosFIR is a high-resolution, robust and proven FTIR spectrometer offering high signal throughput, low-noise and long lifetime of components. atmosFIR has been developed to incorporate the latest improvements and advantages in technology, including:

  • Low cost of ownership
  • Low maintenance cost
  • Robust and light, including the latest in fabrication materials
  • atmosFIRt is provided in a rugged transportable case for mobile site measurements

These advantages come with the benefit of improved performance over existing products, due to the new small, robust, high resolution interferometer with low noise measurement. atmosFIR is fitted with a sensitive DTGS detector, operating at ambient temperature without need for liquid nitrogen or other cooled detectors. Protea continues to offer our powerful PAS software suite, training and support, so that the user is able to achieve the best performance out of the product.

Portable FTIR

atmosFIRt takes the standard 19″ rack form of the atmosFIR multigas analyser and provides it in a field-ready portable form. The outer case is a high-IP rated shell providing robust housing for transportation and use on the most demanding of site installations. None of the features of the cabinet version of the atmosFIR have been lost:

  • In-built O2 sensor
  • Heated inlet filter
  • Automated N2 purge valve
  • Digital and analogue outputs

Highest Resolution Portable FTIR

Normally portable FTIR equipment suffers from low resolution measurement. The atmosFIR FTIR allows however allows for resolution up to 0.7cm-1 (unapodized) allowing for detailed detection and speciation of gas species.

With mobile FTIR equipment, site work often involves the investigation and understanding of emissions or process vents. With atmosFIRt the ability to measure complex mixtures down to low concentrations is available with the high resolution option.

However the real benefit of atmosFIRt is that it is variable resolution! So if there is need for measuring at 4cm-1 or 8cm-1 resolution, the atmosFIRt can be set to this resolution with a simple setting in software. No hardware changes are needed.
