Abstract
The present invention relates to a method for injecting a sample (i.e. a material to be analyzed that may be dissolved in a solvent) in a vaporization chamber or in a pre-column or a gas chromatograper, this method implying separately injecting a co-solvent, with the co-solvent being injected in advance of the sample and/or in a point in the vaporization chamber other than the sample injection point.
Claims22
A method for injecting a sample with co-solvent in a vaporization chamber or pre-column of a gas chromatograph, wherein the co-solvent is injected in advance of the sample into the vaporization chamber or pre-column separately from the sample, in a point other than the sample injection point by using a syringe wherein an air cushion is arranged between the sample and the co-solvent.
