摘要

The present invention is a sample delivery apparatus which can be used to repetitively deliver a sample to a process or an analyzer, either automatically or on demand. The design of the apparatus is such that only the volume of the actual sample delivered is consumed, so that a large number of samples can be delivered with minimum consumption of the sample material. The apparatus of the present invention is particularly useful as an automated method for delivering a sample to calibrate on-line analyzers used to monitor chemical processes.
