How it Works
Point FTIR Technology
The IAQ FTIR operates using a process known as point monitoring. Surrounding ambient gases are channeled into the analyzer via sample tubes to an inlet port. Following this, an internal cell holds the gas sample for analysis.
Next, with FTIR technology, an infrared light passes through the gas sample contained within the cell. Thanks to a physics principle known as the Beer-Lambert Law, an ultra sensitive spectrometer, and Cerex’s proprietary software (CMS), the concentrations of the specific gases within the sample is translated into real-time data.
Common Detectable Gases
Extensive Library with Options for Customization
Cerex has over 350 compounds available for detection with the IAQ FTIR. If your compound is not one of the compounds already available within our database, the Cerex IAQ FTIR may import gas spectra from the numerous FTIR databases on the web (NIST, EPA, PNNL, etc.)
If you have a compound that is not available in a public database, we may be able to work with you to develop a custom spectrum. Detection limits are a function of the IR detector, installed path length, and site conditions. The detection limits shown have been empirically determined from bump tests of fielded instruments at full path-length.
It is efficient as an alarm and easily integrated into your existing alarm system.
*NOTE: If desired target gases are available within the UV spectrum, we recommend Cerex UV Products for better pricing options. If you’re not sure, we can help you find the right analyzer for your application.

Results You Can Rely On
Cerex recognizes that detailed gas monitoring results need to be reliable and available quickly to various stakeholders. For this reason, Cerex engineers developed software to accurately detect and display gases within the air in real time from any location.
On an IAQ FTIR, a user can see results remotely on a phone, tablet, or computer anywhere in the world via a virtual connection.
All data is automatically saved in an easy to access .csv file, and archived daily for future referencing. This feature helps our clients in various ways - from daily use to crucial events such as evidence in court. Early detection translates into quicker response times, reduced environmental impact, decreased plant downtime, and reduced exposure of harmful chemicals to site personnel and community.
