Volatile organic compounds are important toxicants to consider because they may be present in every-day items (paints, cleaning products, etc.), work-place, atmosphere, etc. Hence, monitoring small organic compounds is important in forensic toxicology. Due to the property of these compounds, such as their low boiling points, the gas chromatography may be used for detection. In this laboratory video, the gas chromatography was used to measure the presence of various compounds in samples, including sample mixtures.
This video (18:24) documents in detail the full process of setting up and using the Vernier Mini GC Plus. It begins with setting up the instrument and needle for injections, software set-up and testing standard samples. The samples are composed of VOCs, such as alcohols and ketones.
