主权项

1. A chromatography system comprising:
an injector comprising an inlet port fluidically coupled to a first outlet and a second outlet, in which the injector is configured to receive a fluid sample comprising an oil and analyte of interest through the inlet port, vaporize the received fluid sample and provide the vaporized fluid sample through the first and second outlets; and a trap fluidically coupled to the first outlet of the injector through a fluid line fluidically coupled to the first outlet, the trap configured to receive oil in the fluid sample through the first outlet and trap the oil in the fluid sample while permitting continued flow of vaporized analyte of interest to waste.
