The MultiGas™ 2030 CEM HiSens is an FTIR-based gas analyzer designed for the continuous monitoring of very low emissions in effluent streams containing up to 40% of water and CO2 . With permanently stored calibration spectra, the need for costly reference gas mixtures is reduced. For certain applications such as HCl monitoring, an innovative software configuration also eliminates the need for daily nitrogen background, further increasing the instrument uptime. Furthermore, the robust, MultiGas 2030 is easy to operate and maintain and has a low cost of ownership (CoO).
The MultiGas 2030 analyzer is comprised of a 2102 Process FTIR Spectrometer, an MKS-patented, highoptical-throughput sampling cell, applications-specific analysis software, and an instrument-independent, quantitative spectral library. The MultiGas also incorporates a high-sensitivity thermoelectrically (TE) cooled detector. This analyzer configuration, along with the software analysis package, allows for more accurate, extremely sensitive measurement of several gases, such as HCl, HF, formaldehyde and CO2 , in high moisture streams (up to 40%) by producing high resolution spectra which enable the detection and measurement of components without removal of the moisture.
Estimated detection limits are calculated as three times the standard deviation in 40% water and CO2 for a typical scan time of 1 minute. The table below shows the components and the detection limit for components that are visible when running the MultiGas 2030 HiSens. Figure 1 shows two weeks worth of continuous HCl measurements when using the MultiGas 2030 HiSens at a cement plant, demonstrating the very high sensitivity and reproducibility of the instrument.
|Component||Detection Limit||Recommended Range|
|HCl||30 ppb||0-3 ppm|
|HF, formaldehyde, N2 O, CH4 , CO||10’s of ppb||Application dependent|
