Abstract:
A process for analyzing a fluid sample comprising:collecting a fluid sample in a sampling unit having a cavity for containing the fluid, at least one passage which connects the cavity to a source of the fluid sample to aspirate the fluid sample from the fluid sample source into the cavity and from which the fluid sample is injected into an analyzer device, a pressure varying device disposed in the cavity which provides control of pressure of the fluid sample in the cavity and a heat source which heats the fluid sample in the cavity;controlling at least one of the pressure of the fluid sample in the cavity with the pressure varying device and the temperature of the fluid sample in the cavity with the heat source to maintain the sample in the cavity to have at least one of pressure and temperature substantially identical to at least one of the pressure and the temperature of the sample at a time of collection in the cavity from the fluid source; andinjecting the fluid sample from cavity into the analyzer device with at least one of the temperature and the pressure substantially identical to at least one of the temperature and pressure of the fluid sample in the cavity at the time of collection and thereafter analyzing the fluid sample.
