Genevac
has announced an applications report that details how its
has been used by a leading testing laboratory to develop a new
sample preparation method to help curb sports doping.
Recent developments in applying mass spectrometry to proteomics means that it
is becoming feasible for doping laboratories to routinely detect and confirm
the abuse of peptide hormones by sportsmen and women. Using mass spectrometry
to detect and confirm the abuse of peptide hormones is preferred to the use of
immunoassay techniques as the methodology is able to positively differentiate
between endogenous insulin and its synthetic analogues. To use LC-MS techniques
to detect synthetic insulin however requires that samples are extracted and
concentrated prior to analysis. This traditionally time consuming procedure
requires at least one evaporation of a solution with high water content.
Using a miVac Duo sample concentrator the Australian Sports Drug Testing Lab
was able to significantly improve their sample preparation method for synthetic
insulin's in serum. Using the miVac Duo - sample preparation times were
reduced from several days to just 2 hours and better and more consistent
recoveries were obtained than using the traditional nitrogen blow down
evaporation method.
Affordably priced the miVac concentrator sets the standard for careful and
speedy biological sample concentration and drying from a variety of sample
formats including tubes, microplates and vials. Compact in design - miVac
concentrators feature built-in special methods for working with alcohols, water
and water mixtures to improve performance and optimise concentration
times. Comprising three models of varying capacity each miVac
concentrator features full LCD display with digital control and programming of
time and temperature to minimise the chances of heat damage to your
samples. The miVac pressure controller helps further to optimise
concentration through smoothing the onset of concentration and preventing
sample splashing. Offering unmatched performance, sample safety,
versatility and ease-of-use - miVac is the first biological sample concentrator
system with modules designed to work together and also look good.
