The vapor gas is provided to a measuring instrument such as a chromatograph and the individual constituent components and the BTU value of the gas are determined to an accuracy of within +/?0.5 mole percent and 1 BTU, respectively.Type: ApplicationFiled: September 30, 2011Publication date: January 26, 2012Applicant: MUSTANG SAMPLING LLCInventors: Kenneth O.

Publication number: 20110290041Abstract: The present invention discloses a sampling component comprising a sampling body that can be electrically heated and the outer surface of which has a wiping sampling area; and an insulated handle that is connected with one longitudinal end of the sampling body. The sampling component according to the present invention contacts directly the contacts of an external power supply after being disposed in a analysis chamber, the power supply is turned on to heat the sampling body so as to realize sample pyrolysis, and the power is turned off immediately after the sampling component is taken away. Thus, the power supply of the sampler can work discontinuously so that the power consumption of the system is reduced, meanwhile, the system malfunction caused by a long-term work of the sampling device under a high temperature can be avoided. The present invention further discloses a sampling device having said sampling component and an ion mobility spectrometer having the sampling device.Type: ApplicationFiled: December 1, 2010Publication date: December 1, 2011Inventors: Yaoxin Wang, Yangtian Zhang, Jin Lin, Bin Xue, Wen He, Hua Peng, Peng Jiao
