This article explores three case studies where autosampler injection programs help to (i) reduce the carry-over observed for large nucleic acids during anion-exchange chromatography (AEX), (ii) reduce peak distortion and breakthrough for monoclonal antibodies (mAbs) during hydrophilic-interaction chromatography (HILIC), and (iii) facilitate dissolution of lipid nanoparticles (LNPs) so that a size-exclusion chromatography (SEC) method can be applied for ribonucleic acid (RNA) payload analysis.

LCGC International spoke with Shawn Anderson, Associate Vice President of Digital Lab Innovations at Agilent Technologies; Marco Kleine, Head of the Informatics Department at Shimadzu Europa GmbH; Trish Meek, Senior Director, Connected Science, Waters Corporation and Todor Petrov, Senior Director, QA/QC, Waters Corporation; and Crystal Welch, Product Marketing Manager at Thermo Fisher Scientific about the latest trends in data handling.

Researchers have evaluated the possibility of analyzing finger sweat through liquid chromatography-mass spectrometry (LC-MS) to ensure medication adherence and as a semi-quantitative tool in therapeutic drug management assessment and report positive results.

A technique to measure total phenolic content (TPC) in vegetable oils through analysis of images captured by a cellphone may prove to be easier to utilize than the traditional methods of ultraviolet/visible (UV-vis) spectrophotometry, high-performance liquid chromatography (HPLC), and gas chromatography (GC).

A recent paper introduced a compressed fluid-based separation process that combines carbon dioxide and ethanol to isolate portisins previously hemi-synthesized from blueberry surplus anthocyanins. The performance of the two-step separation process was compared favorably to centrifugal partitional chromatography (CPC) and conventional reversed-phase liquid chromatography (RPLC) findings that were reported in terms of portisins content in the extract, process throughput, process efficiency, and total solvent used.

Researchers investigated the use of electric field in dried blood spot (DBS) sample preparation for the detection of steroids in newborns using liquid chromatography-tandem mass spectrometry (LC-MS/MS) using both regular electroporation cuvettes and a custom vial setup.
