A trap configured to remove oil in a fluid sample to be analyzed using a gas chromatography system, the trap comprising:
- a coupler configured to fluidically couple to a fluid line fluidically coupled to an injector;
- a split fluid path fluidically coupled to the coupler, the split fluid path comprising an inlet, a first outlet and a second outlet, the split fluid path configured to receive sample provided to the coupler through the inlet of the split fluid path and to split the received sample into a first flow provided to the first outlet and to a second flow provided to the second outlet;
- and
- a trap fluid line fluidically coupled to the first outlet of the split fluid flow path and configured to condense oil in the fluid sample received through the first outlet and configured to permit continued flow of vaporized analyte of interest in the fluid sample to waste.
A gas chromatography system configured to receive a fluid sample comprising an oil and an analyte of interest through an injector and provide at least a portion of the fluid sample to a chromatography column fluidically coupled to the injector, the gas chromatography system comprising:
- a housing configured to receive the chromatography column and sized and arranged to position the chromatography column within the housing;
- and
- a trap positioned at least partially external to the housing and configured to fluidically couple to the injector through a first fluid line, the trap configured to receive and condense the oil in the fluid sample.
