HPLC columns packed with Eurospher II material from KNAUER are the new high quality workhorses for a wider range of applications.
HPLC columns packed with Eurospher II material from KNAUER are the new high quality workhorses for a wider range of applications.
With a spectrum of twelve different modifications Eurospher II can be used for a wide range of applications in standard and rapid resolution HPLC up to a maximum pressure of 700 bar (10150 psi). With four different C18 types featuring different levels of endcapping, most reversed phase applications are covered. The ultrapure Eurospher II spherical column material is available with a particle size from 3 µm up to 15 µm for easy up/down-scaling and method transfer between analytical and process scale.

Paraben Exposure and Childhood Obesity Risk in Preschoolers: UPLC-MS/MS Insights from Recent Study
July 14th 2025Researchers speculating that exposure to paraben in early childhood is associated with changes in satiety hormones performed analysis of urinary methyl, ethyl, propyl, and butylparaben (MeP, EtP, PrP, BuP) levels in 4–6-year-old children, using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).
GC-MS Sheds Light on Chemical Communication Between Desert Locusts
July 9th 2025A multinational research team used behavioral assays and gas chromatography-mass spectrometry (GC-MS) to examine short- and long-term interactions between juvenile and adult desert locusts to test their hypothesis that cross-stage interactions influence juvenile cohesion and physiological traits.
