description The present invention provides a mud shale thermal release C5-C14 hydrocarbon preparation and online chromatographic analysis method, which comprises that: 1, a mud shale sample is grinded into particles, and are in the quartz sample boat of a tubular furnace; 2, the tubular furnace is heated under helium gas purging, and hydrocarbon components of the sample are enriched in a liquid nitrogen cold trap; and 3, after completing the enriching, a chromatograph is started, the online enriching tube is rapidly heated, and the thermal release hydrocarbon enters the chromatographic column through a high temperature six-way valve along with carrier gas so as to separate. With the mud shale thermal release C5-C14 hydrocarbon preparation and online chromatographic analysis method of the present invention, the incomplete heavy-component thermal release caused by the large sample particles or the low thermal release temperature is avoided, the online chromatographic analysis and the sample preparation for other analysis items can be concurrently performed, the oil-rock comparative study can be performed, the mud shale can be subjected to quantitative evaluation, and advantages of convenience and environmental protection are provided.
