Horizon Technology (Salem, New Hampshire), a manufacturer of automated sample preparation equipment, has announced that it has partnered with the Water Environment Federation and the International Water Association to promote World Water Monitoring Day (WWMD) 2008. WWMD is an international education and outreach program that builds public awareness and involvement in protecting water resources around the world by engaging citizens to conduct basic monitoring of their local water bodies. The month-long program begins each year on September 18 with a data entry deadline of December 18. A test kit enables citizens to sample local water bodies for water quality parameters such as temperature, acidity, clarity, and dissolved oxygen content.
Study Explores Thin-Film Extraction of Biogenic Amines via HPLC-MS/MS
March 27th 2025Scientists from Tabriz University and the University of Tabriz explored cellulose acetate-UiO-66-COOH as an affordable coating sorbent for thin film extraction of biogenic amines from cheese and alcohol-free beverages using HPLC-MS/MS.
Multi-Step Preparative LC–MS Workflow for Peptide Purification
March 21st 2025This article introduces a multi-step preparative purification workflow for synthetic peptides using liquid chromatography–mass spectrometry (LC–MS). The process involves optimizing separation conditions, scaling-up, fractionating, and confirming purity and recovery, using a single LC–MS system. High purity and recovery rates for synthetic peptides such as parathormone (PTH) are achieved. The method allows efficient purification and accurate confirmation of peptide synthesis and is suitable for handling complex preparative purification tasks.
