A new analytical procedure for water content in LPG

Speakers: Karl Robertson, Dr. Michael Hahn, Dorit Wilke

Moderators: Tom Lynch CChem FRSC

ppm water content in LPG and all gas mixtures can now be accurately determined by coulometric Karl Fischer titration.
The latest eLearning session presented by ECH Elektrochemie Halle explains in detail how this new ASTM procedure allows you to test ppm water in your laboratory and directly at the sample point.
The first question is, why is the water content of LPG and gas so important?
Substances with corrosive promoting properties have to be monitored and kept to a minimum. Water is one of the most corrosion promoting substances found in LPG and gas.

Mr Karl Robertson, Dr Michael Hahn and Dr Dorit Wilke describe a new analytical procedure, which has now been incorporated into a new ASTM method for water content in LPG by coulometric Karl Fischer titration. The ECH procedure simply removes interferences caused by mercaptans and H2S enabling accurate determination of water content in LPG and all gas types down to 1ppm.
