Abstract
A sample delivery apparatus which can by used to repetitively deliver a sample to a process or an analyzer, either automatically or on demand. The sample delivery apparatus can be sealed under an inert atmosphere, thus minimizing the possibility of changes in the sample due to, for example, evaporation, hydrolysis, or oxidation. The design of the apparatus is such that only the volume of the actual sample delivered is consumed. Therefore, a large number of samples can be delivered with minimum consumption of the sample material. The sample delivery apparatus can be used to deliver both liquid and gaseous fluids. The present sample delivery apparatus is especially useful as an automated method for delivering a sample to calibrate on-line analyzers used to monitor chemical processes.
