David Wheeler Posted April 12, 2010 Share Posted April 12, 2010 Can anyone help with a simple method for determining the water level in toluene in the field. This will be below the solubility limit of water in toluene, i.e. well under 0.5%? e.g. Is there a dip slide or an indicator solution? I'm trying to avoid instrumental techniques as it has to be carried out away from the lab. Thanks! David Link to comment Share on other sites More sharing options...
Fuzzwood Posted April 12, 2010 Share Posted April 12, 2010 Portable conductivity meter. I know they use a similar technique when measuring the water content of brake fluid when your car is in the shop. Link to comment Share on other sites More sharing options...
