1. A system comprising:
a first oven containing an SVOC focuser and an analytical column;
a thermal desorber fluidly coupled to the SVOC focuser and analytical column;
a VOC focuser fluidly coupled to the SVOC focuser;
a plurality of valves configured to:
introduce a first flow of sample from a sample extraction device contained in the thermal desorber to the SVOC focuser, through the SVOC focuser towards the VOC focuser, wherein the SVOC focuser is configured to retain first compounds and the VOC focuser is configured to retain second compounds;
after the SVOC focuser retains the first compounds and the VOC focuser retains second compounds, introduce a second flow of the sample from the VOC focuser and the SVOC focuser to the analytical column, wherein the second flow transfers the first compounds and second compounds to the analytical column; and

an analyzer fluidly coupled to the analytical column, wherein the analyzer is configured to conduct a chemical analysis of the first and second compounds after the first and second compounds traverse the analytical column.
