ChromaBLOGraphy: Speed up Separations and Maximize acetylene, propadiene and methylacetylene Response using High flow and Short alumina MAPD columns

Last week I had the chance to do some labwork at Restek on light hydrocarbon analysis looking at fast analysis of trace polar hydrocarbons (acetylene, propadiene). For this application, a new column was developed : AluminaBOND / MAPD.  See also:  http://blog.restek.com/?p=2670   I always was amazed by the selectivity of the alumina adsorbent for hydrocarbon [...]

ChromaBLOGraphy: New Alumina PLOT provides Highest Acetylene/Propadiene Response and extended Maximum Temperature

During last ISCC symposium in San Diego, several posters were presented on alumina PLOT technology and application. One poster was about a new alumina columns with improved characteristics. The other poster was about separation behavior of alumina. Here we zoom into the new Alumina technology. In light hydrocarbon analysis, the separation and detection of traces [...]

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 [...]

Restek's PLOT Column Family PCSS1163G-UNV

Restek's porous layer open tubular (PLOT) columns feature an innovative bonding process that minimizes particle release, more consistent flow for stable retention times, and outstanding peak symmetry to improve impurity analysis. Restek PLOT columns are the benchmark for performance.

ChromaBLOGraphy: [24] What do Chromatograms tell us? Base line is Rising with a Near Constant Slope..

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 GC-chromatograms that are obtained from users and discuss some potential causes for the phenomena. Then we can move into some solutions for improvement.   In chromatography, we always like […]
