New Sample Preparation Method Helps Curb Sports Doping
Dec 12 2008
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 LCMS 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 authors of the report were able to significantly improve the 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 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.
