EcoSEC – the new semi-micro GPC/SEC system – goes on tour. PSS and Tosoh Bioscience cordially invite to join the International EcoSEC Road Show with live presentations about modern GPC/SEC solutions.
The tour starts in March in Basel, and will take place in 8 different places throughout Europe. Participation is free of charge. Information on the International EcoSEC Road Show 2010 can be downloaded on the website www.ecosec.eu.
Revolutionary dual flow detector technology, less solvent consumption, increased sensitivity & shorter analysis times
EcoSEC is a compact all–in–one system for high throughput analysis of natural or synthetic polymers by semi-micro GPC/SEC. EcoSEC combines high quality system compounds in an integrated modular solution.
Technical highlights like integrated auto sampler, temperature controlled solvent delivery system, dual flow RI detector for stable RI baseline together with the low system dead volume fulfill all hardware requirements for improved resolution and sensitivity in GPC analysis. EcoSEC can be upgraded with a column switching valve and UV, viscosity and light scattering detectors. The PSS WinGPC software controls the entire system and performs data acquisition and GPC data analysis.
TSK-GEL semi-micro GPC columns are ideally suited to be combined with EcoSEC, as semi-micro GPC offers additional benefits like shorter analysis times, less sample and solvent consumption and even higher separation efficiency.
Fundamentals of Benchtop GC–MS Data Analysis and Terminology
April 5th 2025In this installment, we will review the fundamental terminology and data analysis principles in benchtop GC–MS. We will compare the three modes of analysis—full scan, extracted ion chromatograms, and selected ion monitoring—and see how each is used for quantitative and quantitative analysis.
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.
