A
technical article from Genevac is available that details how its HT-24
centrifugal evaporation system is assisting a commercial flavours and fragrance
company in its quest to find and isolate novel flavour ingredients from nature.
Natural product derived discovery of novel flavour molecules is a highly
complex process. Natural product sources yield complex extracts
containing many components, which often do not lend themselves to processing
and analysis. Conventionally, many steps of fractionation and evaluation are
necessary until a compound is obtained from natural sources at the purity
required for structural analysis. In the article a state of the art
fractionation process using a Sepbox® Preparative HPLC - SPE system* and a
Genevac® HT-24 centrifugal evaporator is described. The Sepbox enables two
dimensional, preparative scale fractionation of natural products using high
performance liquid chromatography – solid phase extraction (HPLC-SPE). In
sequential HPLC-SPE / HPLC-SPE steps individual components are isolated from
complex mixtures. Each separation run produced 320 samples of approximately
45ml volume.
A Genevac HT-24 Evaporator was chosen to dry the samples because of its high
sample capacity, unique technology that eliminates cross contamination due to
sample bumping and automated monitoring of temperature and pressure to prevent
sample degradation. Able to evaporate 192 sample vials simultaneously the
HT-24 took just two days to dry all the fractions ready for further liquid
handling and testing.
Compact in design and offering a very high capacity for a wide range of sample
formats including microplates, tubes, vials, fraction collector racks and
Genevac’s hybrid HPLC blocks the HT-24 offers the versatility and productivity
to assist chemists in high-throughput environments. The high-throughput design
of the HT-24 allows up to 96 shallow-well microplates to be dried down at the
same time, while capacity for standard 16 x 100mm fraction collector tubes is
an outstanding 576 tubes per run. Benefiting from Genevac’s 20+ years of
designing centrifugal evaporators the HT-24 is easy to use, reliable, robust
and safe to both operator and sample integrity. Further aiding productivity the
HT-24 includes facility for rapid defrosting, and pull-out sample shelves for
easy loading and unloading.
