The QTS-1 is a compact, easy to use 8-sensor array measurement
system that is to generate chemical profiles of samples. The sample may be contained in
either sample jars or vials or introduced from an external sampling system. The profiles
are processed in software and compared to an on-line library for rapid identification. The
results may be displayed in a number of different ways ranging from similarity maps to
simple yes/no identification. A typical general method would involve creating a library of
response patterns for acceptable standards (a statistically significant population) e.g.
food flavours, taint free plastics etc. and then to use the library to ascertain whether
the unknown sample is the same or different, close or far from the standard population.
The resulting method is a powerful quality control tool capable of rapidly identifying
