High‐speed gas chromatography using an on‐column thermal A short narrow‐bore 50 μm column with an on‐column thermal desorp‐ tion modulator provides a technically simple and reliable method to generate high‐ speed gas chromatograms. A thermal desorption modulator prepared on the column but operated at a lower temperature functions as a sample introduction device.
Organic GPC Columns - 日本分析工業株式会社 High speed Organic GPC Columns Chloroform or THF JAIGEL-HH Series. The original organic GPC JAIGEL-H series columns can now flow at 7.5 mL/min and become JAIGEL-HH series that is twice faster than H series. JAIGEL-HH series have the exact same packing material that have been well received for many years.

Recent Progress in Monolithic Silica Columns for High-Speed Monolithic silica columns have greater through-pore size / skeleton size ratios than particulate columns and fixed support structures in a column for chemical modifi ion resulting in high-efficiency columns and stationary phases. This review looks at how the size range of monolithic silica columns has been expanded how high-efficiency monolithic silica columns have been realized and how
