Abstract
A moveable end (ME) sample cylinder device is provided which employs a method of collection wherein the initial cylinder volume of the collection vessel or sampling cylinder is zero. The sample cylinder is inserted into the pressurized gas (or fluid) source for spot sampling thereof, said sample cylinder employing a piston or moveable end configured such that purging of the cylinder sample cavity is not required, since the sample cavity volume is essentially eliminated prior to sampling by the location of the piston within the cavity, the cavity expanding upon sampling via piston movement within the cavity. Also contemplated is a cap/body (CB) spot sample cylinder having a low internal volume and which can be inserted into a pressurized process through common valving. Insertion of the CB sample cylinder into the process eliminates purging of interconnecting tubing and also eliminates the impact of low ambient temperatures which can otherwise alter the spot sample composition. The CB sample cylinder cap may be provided to function as a fill/empty valve.
