Sample inlet for analysis instrument and method of sample analysis

Abstract: A sample injection system for a gas chromatograph or other analysis instrument is described. The sample injection system can be used in conventional gas chromatographs containing a detecting device and an internal heat source to provide temperature-programming capability for analyses involving thermal extraction of hydrocarbons and other gaseous products from a solid or liquid sample. The injection system includes a sample chamber having a sample inlet and an outlet, means to control the temperature of the sample chamber, a carrier gas inlet to the sample chamber, and means defining a flow path extending from the sample chamber outlet and for absorbing heat from the internal heat source. A method for analyzing geological samples to determine certain petroleum-related characteristics is also described.

Sample transport with rotary air interlock charging and discharging means

Abstract: A compact, sealable sample transport apparatus for conveying material from a supply to a combustion chamber, includes an elongated ladle member longitudinally moved in a conduit to the combustion chamber and coacting rotary magazine and transfer plate members, sealed with respect to one another so as to enable discrete analytical specimens to be loaded into and, after analysis, discharged from the ladle member without substantial exposure of the interior of the apparatus to the ambient atmosphere.

Sample injection system for chemical analyzer and method of sample analysis

Abstract: A sample injection system for a gas chromatograph or other analysis instrument and a method of sample analysis are described. The injection system comprises a sample chamber, a sample inlet at one end of the sample chamber, a sample outlet at the opposite end of the sample chamber, means for cooling the sample chamber and means for introduction of a carrier gas into the sample chamber. In one embodiment, the injection system further includes a second sample chamber openly connected with the first sample chamber so as to allow the transfer of a solid or liquid sample from the first chamber wherein the sample can be contacted at ambient temperature with a flowing carrier gas, to a preheated second chamber, wherein hydrocarbons are thermally extracted from the sample. The injection system and method are particularly suited for thermal analysis of geological samples to obtain information useful in petroleum exploration.

Device for automatically injecting solubilized or diluted substances

Abstract: The invention concerns a device for automatically injecting substances solubilised or diluted in a solvent for a gaseous phase chromatographic analysis column (14), wherein it includes a concentration/calcination chamber (10), a vaporization chamber (12) in contact with the chromatographic column (14), a sample support (16) moving in the concentration/calcination chamber between a first position in which the sample is in the concentration/calcination chamber and a second position in which the sample is in the vaporization chamber, as well as a system (18) for scavenging the two chambers with a vector gas.

Apparatus for generating carrier gas-test specimen vapor mixtures for delivery into a gas chromatograph

Abstract: Delivery of a test specimen vapor--carrier gas mixture into a gas chromatograph is accomplished by means of an apparatus including a barrel to receive a probe which serves to maintain the test specimen in contact with carrier gas within the barrel, a heating coil disposed around portions of the barrel housing the sample, and a compression seal releasably bearing against a portion of the probe to prevent air flow into and gas flow from the open end of the barrel.
