“…Since our first report on on-column injection [l] Schornburg et a/ [2] have presented a survey on sampling techniques for capillary GC. While conventional injection with and without splitting have been investigated fundamentally, on-column injection as a new technique has not yet been described in a way that will serve as a guide for users.…”

SummaryDuring one year continuous use of on-column injection, the typical advantages described in our first report have fully been confirmed. In addition the analysis of large sample volumes has proved promising. Only minor modifications have been applied to the on-column injector device. Broad evidence has been gathered showing that full separation efficiency of the capillary columns after on-column injection is attained only when cold trapping or the solvent effect, as band shortening mechanisms, are working. While, under the conditions of on-column injection, cold trapping is less efficient than with other injection techniques, the opposite holds true for the solvent effect. Compared with splitless injection, the danger of excessive solvent condensation on the column is increased. A working rule is presented for establishing the optimal chromatographic conditions for handling large sample volumes while ensuring full separation efficiency yet avoiding harm to the column.

“…Capillary GC is the technique of choice for such analysis, provided that a sampling system forthe whole transfer of solutes from highly diluted samples is used. The splitless injection mode [l ], the moving needle injector [2], and more recently cold on-column injection [3] are adequate for this aim.…”

“…These materials include glass lined metal tubing, noble metals, fusedsilicaand all glassinterfaces [2][3][4][5][6].Suitabilityofeach of these materials depends on its intrinsic inertness towards adsorptive and catalytic activity, the ability to deactivate the surface and carrier gas interaction with the surface. Platinum/ iridium (Ptllr) tubing has been used to connect capillary columns in gas chromatography and in GClMS interfaces.…”
