quality control using impartial flavour signatures
Compared to conventional analytical equipment G.A.S. instruments
allow a very straight forward and still reliable analytical approach to
test gaseous samples same as directly from the headspace of raw
intermediates and finished products.
Our unique combination of a gas
chromatograph in combination with an IMS as detector plus sampler changer assures an easy
and reliable sampling, ideally targeted to several quality control related
applications where reliability is critical.
G.A.S. systems provide outstanding sensitivity in the low
ppb/µg/L-range –which for many compounds is comparable to the range of the
human nose- so that samples can be analyzed “as is”.
By that time consuming and laborous sample handling
and pre-treatment steps that can change their characteristics can be
Very easy to use menu developed to serve as a straightforward
approach for non-academic personnel.
Efficiently support sensory panels with impartial analytical
results without significant effort or requirements, avoiding time and
labour-intensive GC-MS analysis.
Our instruments can be used in different set-ups: Directly
attached to the process using the GC-IMS as ‘on-line’ monitoring device or 'at line' using the
FlavourSpec® for headspace analysis of solids and liquids.
Both systems can detect/identify and quantify single compounds/markers
using the ‘GCxIMS Library Search’ software, or alternatively peak pattern analysis to provide result orientated tests for:
freshness, storage conditions, best before date
diacetyl and pentanedione during the beer brewing process
control of commodities and finished products:
juices and other mixtures
authentication (habitat, detection of frauds, counterfeits)
prove of product flavours
of sensory panels
Detection of off-smells
composition, Blending (green tea, coffee, cigarettes etc)
adulteration under specific storage conditions
of manufacturing process
VOCs from packaging/plastics/papers
