Product Quality Control

Reliable 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 materials, 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 avoided.

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:

Food freshness, storage conditions, best before date
Determination of VDKs diacetyl and pentanedione during the beer brewing process
Quality control of commodities and finished products:

Ingredients and herbs
olive oil
hops
fish, meat
diary products
fruit juices and other mixtures

Product authentication (habitat, detection of frauds, counterfeits)
Impartial prove of product flavours
Support of sensory panels
Early Detection of off-smells
Flavour composition, Blending (green tea, coffee, cigarettes etc)
Product adulteration under specific storage conditions
Optimisation of manufacturing process
Outgasing VOCs from packaging/plastics/papers

Terpenes are a diverse class of organic compounds produced by various plants, including cannabis.

Understand how a change in formulation of food or beverage affects the product's flavour.

The quantification of diacetyl and pentanedione (vicinal di-ketones) to determine the end of the brewing process is the key criteria in the global beer industry.

Crisps and frying oils - when exposed to light and/or temperature- oxidize with time, producing a wide series of aldehydes, ketones and acids so that they loose their flavour or become rancid.

Quality control, authentication, habitat, grade and shelf life of green tea are not only due to their significant economic aspect but also with respect to natural stimulants and quality of life of high relevance.

The quality control of rice as the most widely consumed staple food providing a fifth of the world’s calories on a daily basis has an outstanding importance regarding human health and nourishment.

Tobacco and cigarettes belong to the world's most important luxury foodstuffs/stimulants with a global turnover in the high hundreds of billions USD. A sophisticated quality control regarding several aspects is a MUST.

High quality native olive oils is a pure and healthy natural product that stands out due to a complex and rich flavour. There is a mayor interest of all parties involved throughout the entire supply chain assure a best quality and pay an adequate price for it.

Milk and diary products belong to world's most nutritious and commonly consumed foodstuff. Their variety in composition, ingredients and taste seems endless. Product same as flavour quality control are crucial criteria concerning customer satisfaction.

Rapid monitoring of acetaldehyde down to the low ppb range

The intrinsic sensitivity of ion mobility spectrometry combined with distinguished enrichment properties of thermal desorption by ITEX DHS leads to outstanding possibilities in the field of trace analysis where extremely low detection limits are required.
