Latest multigas FTIR analysers can be hired

DX4040

FTIR gas analysers have become popular in a wide variety of gas detection and monitoring applications because of their ability to measure almost any gas. However, the cost of this equipment can exceed the budgets of those that could benefit from this sophisticated technology, so Quantitech has established a small range of FTIR gas analysers that are available for hire.

Typical applications for FTIR gas analysis include industrial emissions monitoring, occupational safety surveys, engine exhaust testing, process monitoring, leak detection, emergency response, chemical spill and fire investigations, breathing gas analysis and many others.

FTIR
An FTIR spectrometer obtains infrared spectra by first collecting an ‘interferogram’ of a sample signal with an interferometer, which measures all infrared frequencies simultaneously to produce a spectrum.

Sample identification is possible because chemical functional groups absorb light at specific frequencies. In addition, through calibration of the spectrometer, it is possible to determine the intensity of the absorption (relative to the component concentration).

The Gasmet library of reference spectra consists of reference files of gas spectra measured to-date with different Gasmet gas analysers. The library contains hundreds of spectra and each reference spectrum contains both quantitative and qualitative information about the component. This means that users are able to analyse samples retrospectively if a new parameter becomes of interest.

Alti livelli di precisione e bassi livelli di manutenzione sono raggiunti a seguito di calibrazione continua con un laser He-Ne, che fornisce una scala stabile numero d'onda. Inoltre, segnale alto spettrale di rumore e di alta precisione wavenumber sono caratteristici del metodo FTIR. Questo produce alta sensibilità analitica, accuratezza e precisione.

Emissions monitoring

In grado di monitorare più gas contemporaneamente, anche in presenza di emissioni calde, corrosive e con elevata umidità, l'analizzatore FTIR Gasmet è ideale per un'ampia varietà di applicazioni di monitoraggio delle emissioni. Il Dr Andrew Hobson di Quantitech afferma: "La DX4000 è popolare per il noleggio a causa della sua portabilità e flessibilità; ha le stesse funzionalità di un CEMS montato su rack, ma offre agli utenti la possibilità di misurare quasi tutti i gas in più siti, quindi può essere utilizzato per verificare CEMS fissi e per lavori di ricerca e investigativi. "

The DX4000 is typically set up to measure H2O, CO2, CO, NO, NO2, N2O, SO2, NH3, CH4, HCl, HF and a variety of different VOC´s, but additional gases can be added without any hardware changes. Easy-to-use Calcmet™ software is supplied with the analyser and results can be displayed in ppm, mg/Nm3 or Vol-%. All measurement data and spectra can be stored for later analysis.

The Gasmet FTIR analyser is MCERTS approved for nine of the most important parameters. However, with such a vast array of measurable parameters possible, existing users are also able to take measurements that help improve process control.

Ambient/workplace monitoring

The new Gasmet DX4040 portable FTIR multi-gas analyser is also available for hire from Quantitech. This unit contains exactly the same analyser as the other Gasmet FTIR instruments, but is housed in a backpack and communicates wirelessly with a PDA.

The PDA enables users to measure up to 25 (user defined) gases simultaneously, but the DX4040 can also operate with a laptop or PC to analyse spectra for thousands of gases. This means that the technology can be employed for the investigation of unknown gases.
Quantitech’s Dr Andrew Hobson is available to offer help and advice on the use of FTIR gas analysis and is responsible for configuring each rented analyser to best meet users’ needs.
