ABSTRACT:
The present invention is a pressurized fluid sample injector system consisting of a sample needle, multiport valve, sample loop, metering syringe and a pressure assist pump. The speed of sample transport into the sample loop is increased by pressurizing the fluid in the system and metering the sample into the sample loop. The elevated system pressure allows the fluids to be moved faster than the vapor pressure would normally allow in a system at ambient pressure.
