Proper equipment and procedures are essential for obtaining representative samples from an LPG stream.
Sampling of light liquid hydrocarbons generally involves one of two methods:
Flow-proportional composite sampling by a mechanical device
Physical transfer of hydrocarbon fluids from a flowing pipeline or other source into a suitable portable sample container.
If sampling by proper techniques and equipment supports careful chromatographic analysis, full advantage of accurate mass measurement of LPG can be realized.
