The essence of the overhead analysis experiment is that the volatile sample is heated and volatile gasification, then the sample forms gas at the top of the sample bottle; Sampling needle absorbs gas to do gas chromatography detection. So laboratory bottle for top space analysis is named headspace vial.
In order to achieve the accuracy of experimental data, special attention should be paid to the preparation of samples and instrument settings. Headspace vial, lids and lid pads are important, but those factors are often overlooked. Be sure to use the right headspace vial and lids.
At present, there are various sizes of headspace vial, such as 1.5ml, 2ml, 6ml, 20ml, 40ml. The use of a standard sample vial to ensure adequate top space, that must be achieved in a standard ratio. And samples that are not over-diluted must be used. Usually the reserved capacity after comparison should be 50% of the sample volume.
