Contemporary capillary columns for gas chromatography

Evolution of Organic Analytical Methods in Environmental Forensic Chemistry

“…Developments in column technology for gas chromatography were dramatic during the 1970s, proceeding from packed columns to sophisticated glass and fused silica high resolution capillary columns within a few short years (Jennings, 1980;Blomberg, 1982Blomberg, , 1984Novotny, 1989). Lautamo, Schirmer and Jennings (1998) recently summarized column developments over the past half century.…”

Columns: Packed and Capillary; Column Selection in Gas Chromatography

“…They offer high solute diffusivities coupled with excellent chemical and thermal stabilities. The thorough review of polysiloxane phases by Haken (105) and the overview of stationary phases for capillary GC by Blomberg (106,107) are strongly recommended readings.…”

The Column in Gas Chromatography

“…For a more extensive view of the evolution of column technology standard texts [136][137][138][139][140][141][142] and review articles [35, [143][144][145][146] should be consulted. We will present only a brief account of these older methods in the following sections.…”

“…Surface modification reactions are used to improve the wettability of glass surfaces by polar stationary phases and to improve the extent of deactivation by silylation [138][139][140][141][142][143][144][145][146]166]. The static or dynamic etching of soda-lime glass capillaries results in the formation of a regularly spaced array of sodium chloride crystals on the inner surface of the column.…”
