This all-in-one instrument, both electronic nose and ultra fast gas chromatograph, performs overall odor profiling and chemical composition analysis in one run.
To automate sample incubation, headspace generation, collection and injection, Electronic Nose analyzers can be coupled to autosamplers instead of using manual injection. Additionnally, these autosamplers can be further equipped with a variety of devices for extracting or concentrating volatile organic compounds before analysis.
In order to optimize headspace sampling or pre-concentrate volatile organic compounds, various sampling options can be mounted on autosampler or directly on the electronic nose prior to odor measurement and VOC analysis:
Electronic Noses detect and measure organic compounds, whether or not they are an odorant. The Electronic Noses from Alpha MOS use various technologies, among whichGas Chromatography or
Fast Gas Chromatography.
Solid, liquid or gas samples can be analyzed by liquid or headspace injection. With Fast gas chromatography, C20 are analyzed in less than 60 seconds. After a simultaneous injection on 2 columns of different polarities coupled to 2 Flame Ionization Detectors (FID), the 2 chromatograms are treated as a global fingerprint.
For data processing, retention times and peaks areas constitute the raw data.
A common and unique platform of the AlphaSoft software monitors all electronic noses, electronic tongue and electronic eye from Alpha MOS range.
Compatible with Windows XP/Vista/7, AlphaSoft is available in 7 languages: English, French, Spanish, German, Japanese, Chinese, Korean.
AlphaSoft offers numerous advanced functionalities in gas chromatography to optimize GC based Electronic Noses performance:
AlphaSoft uses multivariate statistical analysis and chemometrics to acquire, compute and interpret electronic nose measurements.
AlphaSoft offers various data processing models and different decision tools for qualitative or quantitative analysis in odor evaluation:
