Sample preparation for LC/MS

15th December 2015

Posted By Paul Boughton


Porvair Sciences offer a range of sample evaporators and microplate products optimised for use in conjunction with LC/MS and LC/MS/MS instrumentation.

To facilitate better analysis of very dilute samples by LC/MS, Porvair Sciences nitrogen blowdown evaporators can assist by evaporating solvent to increase concentration thereby increasing sensitivity.

In applications where serum or plasma samples have been de-proteinated using a protein precipitation microplate, such as the Porvair P3 plate, the sample is typically left in acetonitrile. Porvair evaporators provide a quick and easy-to-use method of removing the acetonitrile before reconstituting the dried sample in a solvent system more suitable for LC/MS.

Recently introduced, Porvair Sciences Ultravap Levante nitrogen blowdown evaporator offers rapid programmable dry down of LC/MS samples dissolved in solvents such as acetonitrile, dichloromethane and methanol. With 10 stored programs and a full colour screen, the Ultravap Levante™ is very easy to use and has a range of features to help improve your labs productivity. The Ultravap Levante is the perfect tool to enable you to integrate an automatic dry down step into your LC/MS or LC/MS/MS sample preparation methods.
