Abstract：An on-line monitoring system for non methane total hydrocarbon in hazardous waste warehouse based
on gas chromatography was developed. In this system, the principle of gas chromatography was used to separate samples,
which were ionized by flame ionization detector to form micro current, and then detected by signal amplifier and converted
to hydrocarbon content. The linkage debugging results showed that the indication error of the system was less than±2.5%,
the zero drift was less than±5%F.S.(the percentage of sensor's full-scale error), the range drift was less than±5%F.S.,
and the response time was less than 300 s. All technical performance indexes of the system meet and are superior to the
technical requirements for acceptance and operation of Shanghai fixed pollution source non methane total hydrocarbon
online monitoring system, which has the value of popularization and application.
