Universal quantification using ELS detection and real-time response control
Polymer Laboratories, now a part of Varian, Inc., has published an application note on Universal quantification using ELS detection and real-time response control. The ability of the Varian 385-LC to overcome solvent enhancement effects during gradient elution makes it ideal for quantifying unknown compounds. This application note shows that combined with the improved sensitivity to semi-volatile compounds at sub-ambient temperature, the Varian ELSD offers a simple and accurate solution to universal quantification.
Characterizing Plant Polysaccharides Using Size-Exclusion Chromatography
April 4th 2025With green chemistry becoming more standardized, Leena Pitkänen of Aalto University analyzed how useful size-exclusion chromatography (SEC) and asymmetric flow field-flow fractionation (AF4) could be in characterizing plant polysaccharides.
Investigating the Protective Effects of Frankincense Oil on Wound Healing with GC–MS
April 2nd 2025Frankincense essential oil is known for its anti-inflammatory, antioxidant, and therapeutic properties. A recent study investigated the protective effects of the oil in an excision wound model in rats, focusing on oxidative stress reduction, inflammatory cytokine modulation, and caspase-3 regulation; chemical composition of the oil was analyzed using gas chromatography–mass spectrometry (GC–MS).
