Automated Sample Preparation (ISO 20122) for MOSH/MOAH in Seasoning Oils
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.
Application of LC-UV/MS Workflows to Increase Efficiency in Impurity Profiling of GLP-1 Analogs
June 18th 2025In this study, the unique capabilities of a LC-UV/MS workflow to accelerate analysis are demonstrated in the identification of impurities related to GLP-1 analogs that underwent chemical and thermal stress conditions.
Accelerating Method Development and Manufacturing of GLP-1 Analogs with LCUV-MS
June 18th 2025In this study, we present a QC-friendly LC-UV/MS workflow designed to alleviate the workload on analytical laboratories. Access to orthogonal mass data allows supporting labs to make quicker and more informed decisions during method development, reducing errors, and increasing overall productivity.
