To determine moisture content in sensitive parts, eg connectors, DSM compared three measurement techniques:

• Halogen Moisture Analyzer
• Karl Fisher Titration
• Vaporimetry

Halogen Moisture Analyser

Tests were carried out on Smart Media Card connectors that had been immersed in water for 12 hours and then conditioned at 40ºC and 95% RH for 24 hours to absorb high water content.

All of the techniques gave similar moisture readings. However, the Halogen Moisture Analyzer was easiest to use, for the following reasons:

• No need to cut specimens to small pieces
• Faster
• Portable
• No solvent required
• No vacuum required
• The halogen technology heats the sample in seconds
• The drying temperature can be precisely controlled
