ChromaBLOGraphy: Higher temperature stability and better peak shape of new Restek alumina MAPD column outperforms Agilents PLOT Al2O3 M type

A few months ago Restek introduced a new Alumina PLOT column, that was dedicated for trace methylacetylene(MA)and propadiene(PD), for which it was named Rt-Alumina BOND MAPD. The column does provide highest response for polar hydrocarbons which makes it ideal for purity and impurity analysis of hydrocarbon stream.  Our scientists successfully managed to maintain the loadability [...]

ChromaBLOGraphy: What do Chromatograms tell us? Peak Shape: Reactivity of Alumina

Chromatograms are like fingerprints.  If you can “read” chromatograms well, you often can find a plausible cause. In this series, we will show a series of chromatograms that are obtained from users and discuss some potential causes for the phenomena. Then we can move into some solutions for improvement. A peak shape is observed as [...]
