High-End Sensitivity for Countless Applications
The IRXross is a mid-level FTIR model that achieves high-end level S/N. It enables best-in-class low noise with P-P
values of 55,000:1 for one minute of integration.

Astoundingly Low Noise
The 100 %T line was obtained by successively measuring the background and sample values without placing a
sample in the sample compartment. Excluding the peaks for water vapor and carbon dioxide, the noise level (P-P
value) was within ±0.005 %T, which shows that it can acquire data with low noise.
