Simple quantification of zeolite acid site density by reactive gas chromatography
, 2017The Bronsted acid site densities of ZSM-5, BEA and single unit cell self-pillared pentasil (SPP) zeolites of varying Si/Al ratios were measured using a new technique, reactive gas chromatography (RGC), which utilizes alkylamine decomposition to ...

Multidimensionality in gas chromatography
TrAC Trends in Analytical Chemistry, 1996Many analytical problems require more resolution than a single chromatographic technique can provide. In such cases the separation power can be enhanced by using more than one separation technique or mechanism. The sample is then dispersed in different time dimensions.

Flow field thermal gradient gas chromatography.
Analytical Chemistry, 2015Negative temperature gradients along the gas chromatographic separation column can maximize the separation capabilities for gas chromatography by peak focusing and also lead to lower elution temperatures.
