Solvent Extraction Moisture Analyzers

What is Solvent Extraction?

Solvent extraction is a moisture testing method that involves extracting moisture from a sample using a solvent. The solvent and extracted moisture are then separated, and the moisture content is determined by measuring the change in solvent weight or volume.

How does a Solvent Extraction Moisture Analyzer work?

Solvent extraction moisture analyzers are designed to perform the solvent extraction process automatically. They consist of the following components:

Extraction cell: The sample is placed in the extraction cell.
Solvent reservoir: The solvent is stored in the solvent reservoir.
Condenser: The condenser cools and condenses the solvent vapor.
Moisture trap: The moisture trap collects the condensed solvent and moisture.
Balance: The balance measures the change in solvent weight or volume.

During the extraction process, the solvent is heated and vaporized. The solvent vapor passes through the sample, extracting the moisture. The solvent vapor and extracted moisture are then condensed and collected in the moisture trap. The change in solvent weight or volume is measured by the balance, which is used to calculate the moisture content of the sample.

Advantages of Solvent Extraction Moisture Analyzers

Solvent extraction moisture analyzers offer several advantages over other moisture testing methods, including:
