One spectrum, many gases

How FTIR spectroscopy works

With Fourier transform infrared spectroscopy (FTIR) every compound absorbs infrared radiation at specific frequencies: analyzing the spectrum with algorithms and mathematical models gives the concentration of each gas.

ETG adopted a 5-metre optical path in a low-volume cell, for high sensitivity and fast response (T90 below 60 seconds). Background acquisition, needed to compare the analyzed sample, is an easy, quick and automatic process, and makes it possible to exclude unwanted compounds whose absorption frequencies are very close to those of interest.

Need to measure an additional compound? ETG can supply the new configuration without hardware changes: a few files are enough, even through a remote connection over LAN and WLAN.

Where it is used

Applications of the ETG 9500 FTIR gas analyzer

Emissions & processes

Industrial emissions monitoring

Thanks to its accuracy and the large number of compounds it measures simultaneously, ETG 9500 FTIR is a valuable ally in industrial emissions control, in a fixed analysis system or in its portable version. It monitors CO₂, H₂O, NO, NO₂, SO₂, NH₃, N₂O, HCl and HF.

Healthcare

Anaesthetic gas monitoring

In hospitals, the ETG configuration designed for the operating room keeps the dispersion of anaesthetic gases under control, a real risk for healthcare staff. Fast response and accuracy make it possible to detect a leak quickly and trace its origin. Compounds include nitrous oxide, isoflurane, sevoflurane, desflurane, enflurane, halothane and many others.

Environment & research

Greenhouse gas monitoring

Thanks to its selectivity and low detection limit, ETG 9500 FTIR identifies greenhouse gases in air, such as CH₄, N₂O, CO₂ and water vapour. Reconfiguration only requires software changes that any user can carry out: an essential tool for research as well.

Many other applications

Composting process monitoring, catalyst control, CO₂ quality control, gas purity analysis, toxicity monitoring after fire incidents, leak checks in chemical plants, research in biogas and syngas, volatile organic compounds analysis: FTIR technology makes the analyzer suitable for any use.
