The method uses headspace gas injected into a gas chromatographic column (GC) to determine the original concentration in a water sample. [9] A sample of water is collected in the field in a vial without headspace and capped with a Teflon septum or crimp top to minimize the escape of volatile gases. It is beneficial to store the bottles upside ...

YouTube Creator Awards, commonly known as YouTube Play Buttons or YouTube Plaques, are a series of awards from the American video platform YouTube that aim to recognize its most popular channels. They are based on a channel's subscriber count but are offered at the sole discretion of YouTube.
A GC-VUV and static headspace method was developed using a chromatographic compression strategy that resulted in a GC runtime of 8 minutes. The GC-VUV method uses a flow rate of 4 mL/min and an oven ramp of 35 °C (held for 1 min), followed by an increase to 245 °C at a rate of 30 °C/min.
