Researchers from the Technical University of Denmark (DTC) have used gas chromatography (GC) and high performance liquid chromatography–mass spectrometry (HPLC–MS) to investigate microalgae biomass as an alternative resource for fishmeal and fish oil in the production of fish feed.

This article will focus on the development of an optimized gas chromatography–mass spectrometry (GC–MS) method that improves upon the current EPA and European detection limit requirements for BTEX compounds and meets all other criteria described in EPA Method 524.2 for the measurement of purgeable organic compounds in water by capillary column GC–MS.

The Column

The occurrence of disinfection byproducts in natural waters poses a health risk for humans as well as aquatic organisms. This article presents a method, which was recently developed at the University of Arizona, in Tucson, Arizona, USA, for the fast and simultaneous determination of 15 regulated and unregulated disinfection byproducts.
