Aspectrics’ EP-IR Analyzers Achieve Simultaneous Measurement of Methane, Ethane and Propane in Gas Phase

Aspectrics Inc., the innovator of Encoded Photometric Infrared Spectroscopy (EP-IR) analyzers, announces a new application for the analysis of Methane, Ethane and Propane in Gas Phase using EP-IR technology.

The study was designed to prove the capacity of EP-IR spectrometry to collect sufficient spectral information to enable the development of a multivariate quantitative analysis method for the simultaneous measurement of all three gases. The application showed that Aspectrics’ EP-IR analyzers are capable of resolving several chemical compounds, even if they share a similar chemical composition and subsequent spectroscopic features. This application is designed to offer scientists working in the process industry an efficient and cost-effective solution for measuring hydrocarbon gases. This new application note is available to download free-of-charge via the article webpage.

Achieving 100scans/second, Aspectrics’ award-winning EP-IR MultiComponent™ Analyzers feature a nominal spectral range of 2.5-5.0 microns and an impressive 128 photometric channels. The company’s analyzer was coupled with Aspectrics’ I-Cell gas cell and data was collected using Aspectrics’ Commander™ data collection software which controlled both the spectrometer for data collection and the Environics 4000 gas blender for the delivery of the sample. This easy-to-use configuration allowed laboratory technicians to analyze the samples, freeing up scientists’ time.

Traditionally, Infrared wavelength instruments are limited either in the simultaneous characterization of more than one chemical compound, or by a lack of ruggedness. In contrast, Aspectrics’ MultiComponent™ EP-IR spectrometer, which recently received the R&D 100 Award, is capable of measuring several chemical compounds with the same chemical composition. Aspectrics’ EP-IR analyzer delivered excellent analytical results in calibration and validation and obtained precise values for all measurements of methane, ethane and propane in conditions mimicking the presence of ethane and propane in a pure stream of methane.
