Gas Chromatography Injector Stock Photo crimp vials

The minimum gas flow for direct injection is about 5 mL/min. Direct injection can therefore only be applied to columns, which can cater for higher column flow rates such as, packed columns or 0.53 mm ID columns. These columns can also handle the higher concentration levels because of their increased sample capacity.

Improper vial crimping can be due to many factors: defective consumables, inefficient crimping tools or even inexperience of the technician. An improperly crimped vial will leak when the internal pressure of the vial increases during the incubation time that anticipates the headspace injection.

Dec 14, 2009 · Headspace gas chromatography requires a closed system (i.e. no pressure leaking from the gaseous phase). As a result if the crimping of the headspace vial (which is typically a manual process) is not complete, then it is not a closed system.

Chromatography vials typically have crimp, snap, or screw finishes. Closures may be pre-assembled with septa or the septa purchased separately. Vials with closures are also sometimes sold in pre-assembled sets. Crimp top finishes are used with aluminum crimp seals to create a more permanent closure.

Headspace vials with 20 mm crimp tops and 18 mm screw tops in sizes ranging from 6 mL to 20 mL are available in clear or amber glass. Choose from a round or flat base with a beveled or square edge finish. Round base vials are compatible with most autosamplers and are more easily handled by robotic arms that lift the vial from the tray.
