The Benefits of FTIR Gas Analysis
For decades, FTIR Gas Analysis has been a mainstay in the analytical toolbox of chemists. Heralded for its ability to provide both qualitative and quantitative chemical information in real time, FTIR has been widely deployed across many markets and applications. Exceptional specificity makes FTIR ideal for identifying compounds that can be difficult to detect in the presence of a large number of interferents. Because the entire spectral range is captured for every measurement, additional compounds can be identified post-measurement. Finally, FTIR does not require continuous calibration. Because of FTIR's linear response, calibrations are universal across instruments and can be installed prior to leaving the factory. This makes FTIR ideal for determining unknown compounds by using a library of calibration spectra that can be searched in near real time using MAX-Analytics™ software.
Pushing the Boundaries and The Gas Chromatograph (GC) Detection Myth
For many parameters (speed, discrimination of compounds, calibration, dynamic concentration range) FTIR is superior to GC for most applications. However, it has often been thought that FTIR cannot match GCs when it comes to detection limits. Max Analytical Technologies has now debunked this belief with the release of new and innovative FTIR technologies like our StarBoost™ enhancement. StarBoost™ has enabled FTIR detection limits down to mid parts per trillion (ppt) for some applications, and single-digit parts per billion (ppb) are now routine for more complex applications. But the story does not end with StarBoost™. Max Analytical has developed a complete suite of new FTIR algorithms (MAX-Analytics™) that reveal small ppt and ppb peaks in the presence of large overlapping compounds. The quantitative discrimination of our FTIR algorithm technology is unmatched and, for the first time, challenges many applications thought to be only possible with a GC or less environmentally robust optical technology such as cavity ringdown.
FTIR Gas Analysis, That's What We Do Every Day
While FTIRs are often used to analyze solids and as qualitative laboratory instruments, the focus at Max Analytical is gas phase analysis for industrial applications. Our technology (hardware and software) has been specifically developed for gas or vaporized liquid applications that require detection limits ranging from percent to parts-per-trillion. Our hardware, methods, and calibration library provide the best possible results and can be rapidly tuned to meet the specific needs of our customers. At Max Analytical Technologies we are working hard to reinvent gas phase FTIR every day.
