WebSplit / Splitless Injector는 시료가 격막(Septum)을 통과하여 주입되며, 유리 라이너(Glass liner)가 있는 가열된 챔버(Heated chamber)로 구성되어 있습니다. 마이크로 주사기는 고무 격막을 통과하여 Column의 헤드(Head)에 있는 플래시 기화장치 챔버(Flash vaporizer chamber)로 시료를 주입하는데 사용합니다. WebFor trace analysis split injection is used. In this mode, the entire analyte sample vaporized in the injector goes onto the column. This is called the splitless mode. All the analyte mass in a 1 µl injection goes onto the column, it is not split. Finally, the septum purge outlet prevents septum bleed components from entering the column. The

A microsyringe is used to inject the sample through a rubber septum into a flash vaporizer chamber at the head of the column.

WebThis injector can be used in a splitless mode, in which the entire injected sample goes onto the column, or in a split mode, in which only part of the sample goes onto the column, the remainder vented to atmosphere. For other less usual forms of injector, a specialist book on GC should be consulted. [Pg.250] Web1 okt. 2015 · Split injection can reduce a too-large solute amount down to a volume the column can handle. Sample dilution is an alternative, but it may not be desirable as an extra sample preparation step or a source of possible contaminants.
