Systems and methods for sample analysis

A non-transitory computer-readable medium for a gas chromatography system that comprises (1) a sample loop disposed between a first valve and a second valve, (2) a pump disposed downstream of the second valve, and (3) a sample container disposed upstream of the first valve, the medium having computer-readable instructions stored thereon that, when executed by at least one controller, cause the at least one controller to:

• engage the pump at a first time to modify a pressure inside the sample loop from a first pressure to a second pressure less than the first pressure, wherein the second valve is positioned such that the pump is fluidically connected with the sample loop at the first time;
• and
• open the first valve at a second time subsequent to the first time to flow a sample through the first valve into the sample loop, wherein the pump is configured to remain fluidically connected to the sample loop and turned on at the second time.
