Abstract Title: Application of the On-line Liquid Injector valve System (OLIS) for non-discriminating analysis of condensate and liquids by GC

Abstract Information :

The OLIS valve assembly is intended for an automatic homogeneous introduction of pressurized liquid samples into gas chromatographs equipped with split/splitless capillary inlet. The GC injection of liquid samples with wide boiling point range (i.e. petroleum fractions) suffers of quantification problem due to discrimination between light and heavy compounds.

The OLIS injector valve can be successfully applied for automatic and unattended GC injection of pressurized liquid samples without compromising efficiency and resolution of the capillary column. Some examples of application will be presented such as solvent impurity and light liquid hydrocarbons analysis.
