A NOVEL evaporative methodology for mass spectroscopic (MS) analysis, replacing solid phase extraction (SPE) for preparing environmental samples, is described in a paper available from Genevac. In recent years high performance liquid chromatography coupled with mass spectrometry – or HPLC/MS/MS…
Diclofenac is a non-steroidal anti-inflammatory drug used to treat pain and reduce inflammation in humans and animals, which is implicated in the dramatic decline in scavenger species in some parts of the world. A traditional method of livestock carcass disposal…
NITROGEN blowdown evaporation has been adopted by many labs for the removal of chromatography solvents such as acetonitrile, dichloromethane, hexane, and methanol. The latest blowdown evaporator from Porvair Sciences, the Ultravap Levante, is equipped with an RS232 connection and a…
Environmental laboratory productivity can be ‘significantly improved’ using the Rocket Synergy evaporator, says Genevac. Developed to quickly process large-volume environmental samples, in parallel and without supervision, Rocket Synergy can concentrate or dry 18 ASE tubes or up to six large-volume…
NEW versions of MiniVap and UltraVap blowdown evaporators have been announced by Porvair Sciences. These devices use warm air or nitrogen to speed up the evaporation of common HPLC solvents such as dichloromethane, methanol and acetonitrile from sample vials, significantly…
FINDING and isolating new flavour molecules from natural sources is a complex and laborious process, yet the rewards for finding such a molecule make the effort worthwhile. A new technical article from Genevac details how its HT-24 centrifugal evaporation system…
A NEW microplate evaporator from Porvair Sciences will be shown to the public for the first time at Pittcon 2013. The new UltraVap Mistral (pictured) is the latest version of the company’s popular UltraVap sample concentrator, promising even easier integration…
A NEW microsite dedicated to its EZ-2 series evaporators has been launched by Genevac. The EZ-2 is a series of compact, benchtop, personal evaporators which accurately control vacuum and temperature to enable rapid evaporation of a wide range of solvents…
A NEW low cost, small volume evaporator for synthetic and medicinal chemists has been launched by KD Scientific. The Centrifan PE dries solvents directly in the vial, which the company says increases evaporation efficiency. Many of the problems associated with alternative…
ACCELERATED solvent extraction (ASE) is a well-known method to greatly speed up the concentration of semi-solid and solid samples by employing elevated temperatures and pressures to remove solvents more quickly than would otherwise be possible. Genevac has now launched a…
