Cloud point measurement

Would you like to have the cloud point of your samples measured? The Calnesis laboratory performs this type of measurement.

What is a cloud point of a liquid?

The cloud point of a sample is the temperature above which it presents solid particles which give it a cloudy appearance. This formation may be due to a solubility limit reached at the temperature in question, or else to a solidification temperature.

The cloud point is used in particular to characterize petroleum fractions and diesel and kerozene fuels. Indeed, it then characterizes the minimum temperature of use.

How to measure the cloud point?

Most often, the cloud point of a sample is determined visually, by placing the sample in a closed transparent container and subjecting it to a controlled temperature ramp.

However, there are devices specifically dedicated to this measurement, used in particular in the oil field.
