The FlavourSpec® represents the synergies of a fast gas chromatograph and the outstanding sensitivity of an IMS. It enables the selective detection of Volatile Organic Compounds (VOCs) in the headspace of solid and liquid samples. As result a 3 dimensional spectra as characteristic fingerprint of the sample is achieved and further analyzed using multivariate data analysing tools.
To make the operation of sampling and processing simple and easy the system is set up with an automatic GC headspace injector.
The FlavourSpec operates isotherm in a range of 40-80°C and can be set to >100°C for baking out (cleaning). To better separate compounds the instrument uses a firmware steered ramping by its integrated Electronic Pneumatic Controller.
Besides the instrument itself the FlavourSpec® consists of an automatic headspace injector that does all sample conditioning. The operator just enters the measurement parameters (number of samples, conditioning and run time) via the very easy to operate menu on the sampler.
The FlavourSpec provides an automatic data acquisition on the device and when connected to a PC 3-D data visualization and analysis by G.A.S. Laboratory Analytical Viewer (LAV) software.
