Sample bottle, headspace bottle

Simply put, headspace analysis is the analysis of gases present in the headspace sample bottle. The laboratory bottle used for headspace analysis is called a headspace bottle.

The essence of this experiment is that the volatile sample is heated, volatilized, and vaporized to form gas in the space at the top of the sample bottle, which then diffuses and allows the top gas above the volatile sample in the gas chromatography bottle to enter the gas phase for detection.

Adaptation: When using top gas chromatography to detect volatile compounds or semi volatile mixtures with relatively high boiling points, we need to heat them to vaporize the substance at the top. During this process, due to the liquid (solid or solid-liquid coexistence) sample being located at the bottom, it is possible to measure the substance in the top gas without touching the liquid inside the sample bottle. Top space gas chromatography is suitable for sample analysis of light component volatiles. This measurement technique can effectively analyze the gas in the headspace of liquid samples and be applied in solid-phase dispersion methods.

Top space gas analysis also helps with automated quality control or sample screening. This is achieved through the use of modern instruments and highly renewable samples, enabling the entire experiment to be prepared for analysis in an accurate manner. It should be noted that complex sample matrices are not easily analyzed directly unless sample extraction solutions or formulations are used, but this can be a significant waste of time and resources! So we can choose to use gas phase for detection, and at the same time use a high temperature resistant and highly stable headspace bottle during the process, which is the best choice. In this way, the sample can be directly placed in the headspace bottle for heating analysis without any preparation, which saves both time and money.
