Simultaneous Headspace GC–FID Analysis for Methanol and Ethanol in Blood, Saliva and Urine: Validation of Method and Comparison of Specimens
Gorkem Mergen, Zeliha Kayaalty, Emrah Dural, Vugar Aliyev, Seda Kaya, Serap Yalcin, Ayse Karakus and Tirin Soylemezoglu
This article look at headspace gas chromatography (GC) with flame ionization detection (FID) to determine ethanol and methanol content in biological fluids. This method could be applied to perform confirmatory analysis for routine applications in toxicological laboratories.

Aggregated Singletons for an Automated Purification (ASAP) Workflow
Bhagyashree Khunte and Laurence Phillipe
Aggregated singletons for an automated purification workflow (ASAP) is a purification workflow that provides singleton sample purification, registration and delivery to the materials management department as DMSO solutions for biological screening. This method has a high purification success rate and increases the likelihood of running mini-arrays in a 2–3 day turnaround time, according to the authors.

COUPLING MATTERS
Applications of Matrix Elimination Ion Chromatography for Bromate Analysis
Rong Lin, Kannan Srinivisan and Chris Pol
Ion chromatography (IC) is routinely used for ion analysis. However, the presence of a high concentration of matrix ions in some samples poses a challenging analytical problem, especially for trace-level analysis. This article discusses the benefits of inline two-dimensional matrix elimination ion chromatography (MEIC) to analyse samples with a high-level of matrix ions.

Kromasil Chiral phases stretch the limits for analytical and industrial HPLC. With both coated phases, based on functionalized amylose and cellulose selectors, as well as covalently bonded tartaric acid derivatives, a wide range of selectivity and chromatographic conditions are covered.
