College Unveils New Science Center
The College of William and Mary (Williamsburg, Virginia) unveiled its Integrated Science Center for the fall semester.
The College of William and Mary (Williamsburg, Virginia) unveiled its Integrated Science Center for the fall semester. The building houses the chemistry department, as well as molecular biology labs and a vivarium for the biology department. A variety of instrument rooms are located throughout the ISC, including rooms dedicated to the $155,000 liquid chromatography- mass spectrometer (LC-MS) and the laser system for spectroscopy experiments. The completion of the ISC is only the first phase of what is to be a three-part renovation project. The second phase is the complete renovation of Rogers Hall, which is already underway, and the third phase of construction will link the science center to Rogers Hall along Landrum drive.
Troubleshooting Everywhere! An Assortment of Topics from Pittcon 2025

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.
