Bacteriophages are vital for addressing antibiotic-resistant bacteria, though phage therapies are currently rare. University of Lisbon researchers recently created a new purification workflow to address these concerns.

LCGC EAB member Paul Ferguson has been named a professor by special appointment at the Faculty of Science at the University of Amsterdam.

This work presents an Automated Sample Preparation procedure for MOSH/MOAH analysis of Seasoning Oils. We compare results from a manual epoxidation procedure compliant with DIN 16995 with results based on fully automated sample preparation (epoxidation and saponification) compliant with ISO 20122. In both cases, online clean-up via activated aluminum oxide (AlOx) are used to remove interfering n-alkanes from the MOSH fraction during the HPLC run. Automated data evaluation using a dedicated software (GERSTEL ChroMOH) is presented.

A methodology is presented for the determination of flavor compounds in dietary supplements using Stir Bar Sorptive Extraction (SBSE). Quantitation is accomplished by automating the spiking of Tenax-TA® filled sorbent tubes. A retention time index (RTI) standard is also introduced. The GERSTEL Internal Standard/Dry Purge Plus (ISDP+) module automates spiking of standards, internal standards, or a retention index mix and is used to dry purge sorbent tubes to remove excess water or solvent, that may adversely affect the trapping and transfer of analytes to the GC column.
