Speeding Up evaporation of HPLC Solvents
Porvair Sciences announces new versions of its MiniVap and UltraVap blowdown evaporators that use warm air or nitrogen to speed up the evaporation of common HPLC solvents such as dichloromethane, methanol and acetonitrile from sample vials, significantly improving throughput and removing this common laboratory bottleneck.
Porvair Sciences announces new versions of its MiniVap and UltraVap blowdown evaporators that use warm air or nitrogen to speed up the evaporation of common HPLC solvents such as dichloromethane, methanol and acetonitrile from sample vials, significantly improving throughput and removing this common laboratory bottleneck.
Combining a new 48-well needle head with a dedicated HPLC vial holder that accepts 48 standard 1.5ml vials* transforms any MiniVap or UltraVap system into a high throughput HPLC sample evaporator. Applications that will benefit from the new HPLC sample evaporators include pre-concentration prior to injection (to increase sensitivity) as well as evaporation to dryness of post-column fractions for recovery of compounds.

Analysis of PFAS in Milk by LC-MS/MS
May 15th 2025Dairy milk is one commodity that can be impacted by environmental contaminants, such as PFAS, so it is important to implement extensive, robust, and accurate testing. In this work, a sensitive and reliable method was developed for the analysis of PFAS in milk by LC-MS/MS at levels as low as 0.01 µg/kg.
