Aspectrics introduces new application note for simultaneous analysis of four hydrocarbon gases at ppb-level concentrations using its MultiComponent analyser
This application note demonstrates how the EP-IR MultiComponent Analyser is able to conduct simultaneous quantitative analysis of several hydrocarbon gases (C1-C4) in a mixture at parts-per-billion (ppb) level concentrations.
Designed to respond to scientists' needs in petrochemical, chemical, environmental and process laboratories, this application note can be downloaded free-of-charge.
One of the most striking features of Aspectrics's innovative analyzer is the speed of data collection: one full spectrum every 10milliseconds.
Such scanning speed can translate into applications such as ultra-fast kinetics, parts-per-million (ppm) level quantitative analysis in less than five seconds, or, as demonstrated in this application note, measurement of parts-per-billion (ppb) levels of hydrocarbon compounds (methane [CH3], ethane [C2H6], propane [C3H8] and butane [C4H10]) and carbon monoxide [CO].with integration times of only one to five minutes.
Traditionally, Infrared wavelength generation devices, such as the non dispersive infrared (NDIR) and Fourier transform infrared (FTIR) spectrometers, are limited either in the simultaneous characterisation of more than one chemical compound, or by a lack of ruggedness, respectively.
In contrast, Aspectrics MultiComponent EP-IR spectrometer, recently named by R+D Magazine as one of the Top 100 most technologically significant products introduced into the marketplace over the past year, is not only capable of resolving several chemical compounds even if they share a similar chemical composition (and subsequent spectroscopic features), but also is more cost-effective both in field implementation and ownership due to its NDIR-like ruggedness.) The EP-IR MultiComponent Analyser contains patented encoder disk technology that enables the encoding of full spectral information 100 times per second, resulting in 10millisecond true refresh rate of the chemical information.
Moreover, dedicated on-board processors allow users to monitor processes in real time, even as often as 100 times per second.
Aspectrics quantitative analysis software enables real-time characterization of multiple chemicals in process streams.
The software also communicates analytical results and instrument health information to central network locations, and facilitates full automation of calibration and calibration maintenance in production mode.
