Antec announced last March the corporate name change to Antec Scientific. The name change comes along with a new Corporate Identity and the launch of an updated website later this month.

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.

Researchers from the Universidad Autónoma de Yucatán in Mexico, have used solid-phase extraction (SPE) and gas chromatography–electron capture detection (GC–ECD) to study the effects of organopesticides in the Yucatán region of Mexico.

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.

This is the first in a series of articles exploring current topics in separation science that will be addressed at the HPLC 2017 conference in Prague, Czech Republic, from 18–22 June.
