Apparatus for delivering a calibration standard

A procedure for delivering a sample from a closed pressurized system comprising the steps of:

• (A) actuating an expandable means of a pump to separate said pump into a pressure chamber and a sample chamber, thereby forcing the sample from the sample chamber to a sample valve, said valve having a positionable sample well positioned to allow the sample to flow from said valve into a closed reservoir thereby increasing a pressure in the reservoir,
• (B) releasing actuation of the expandable means, thereby allowing the pressure in the reservoir to effect flow of the sample from the reservoir through the sample valve to the sample chamber of the pump,
• (C) positioning the positionable sample well within the sample valve to deliver the sample contained within the positionable well,
• (D) flushing the sample from the positionable well by means of a carrier gas or liquid, and
• (E) repeating steps A through D.

A procedure for delivering a sample from a closed pressurizable system comprising the steps of:

• (A) actuating an expandable means of a pump to separate said pump into a pressure chamber and a sample chamber, thereby forcing the sample from the sample chamber into a first closed reservoir then from the first reservoir to a sample valve, said valve having a positionable sample well positioned to allow the sample from said valve to flow into a second closed reservoir thereby increasing a pressure in the second reservoir,
• (B) releasing actuation of the expandable means, thereby allowing the pressure in the second reservoir to effect flow of the sample form the second reservoir through the sample valve tot he first reservoir,
• (C) positioning the positionable sample well within the sample valve to deliver the sample contained within the positionable sample well,
• (D) flushing the sample form the positionable sample well by means of a carrier gas or liquid, and
• (E) repeating steps A through D.
