Advancing Science Through Diversity: A Conversation with Women in Chromatography, Part 1
In this first roundtable discussion focused on Women in Chromatography, LCGC International spoke with Diane Turner, Jacqueline Hamilton, and Caroline Gauchotte-Lindsay, who are all leading voices in the LinkedIn International Women in Chromatography group.
FeMS Empowerment Award Winner Josephine Ouma Discusses the Society's Impact On Her Career
March 25th 2025In this second part of our interview with Females in Mass Spectrometry (FeMS) Empowerment Award Winner Josephine Ouma, we discuss her experience with mass spectrometry and how FeMS has impacted her life.
Determining Pharmacokinetics of Milbemycin Oxime in Pekingese Dogs with HPLC
A study conducted at Henan University of Science and Technology (Luoyang, China).aimed to characterize the pharmacokinetic profiles of milbemycin oxime in Pekingese dogs following a single oral (PO) and intravenous (IV) dose. Blood samples were collected at various time points, with milbemycin oxime concentrations measured using a validated high performance liquid chromatography (HPLC) method with ultraviolet (UV) detection.
The Role of SPME Combined with GC–MS for PFAS Analysis
March 25th 2025Emanuela Gionfriddo and Madison Williams from University at Buffalo, the State University of New York, NY, USA discuss the important role that solid-phase microextraction (SPME) techniques with gas chromatography mass spectrometry (GC–MS) can play in the analysis of per- and polyfluoroalkyl substances (PFAS).
Research on plastics in aquatic environments is well-established, but little is known about their presence, pathways, and effects in soil ecosystems. The iMulch project aims to address this need as well as the growing concern of plastic pollution in soils. Focusing on developing and validating methods to detect micro- and macroplastics in soils and drainage waters, with an emphasis on how drainage water impacts municipal wastewater treatment, a key aspect of the study is analyzing plastic emissions from agricultural mulch films. We spoke to Carmen Wolf of the Institute for Environment and Energy, Technology and Analytics e.V. (IUTA) in Duisburg, Germany, corresponding author of a recent paper on the project, about the investigations involved and how separation science was used in their experimentation.
Influence of Concentration in Conventional GPC/SEC and Advanced Detection GPC/SEC
Sample concentration is a parameter that can influence the quality of gel permeation chromatography/size-exclusion chromatography (GPC/SEC) separations and the obtained results. Understanding this influence can help to support the development of reliable GPC/SEC methods.
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.
