There are two types of coulometric reagents: the anolyte (generating solution),which is placed in the anode chamber of the electrolysis cell, and the catholyte (counter electrolyte), which is placed in the cathode chamber. There are also special anolyte for use with ketones, lower carboxylic acids and silicone oils. AQUAMICRON™ can be used in coulometric moisture measurement systems sold by various companies, and it has a worldwide reputation for excellent performance.

AQUAMICRON™ FLS
| Use | Suitable for alcohols, esters, benzene, toluene, inorganic gases, etc. | |
|---|---|---|
| Characteristics | Easy to use | AQUAMICRON™ AXI or FLS is a single-solution type reagent. It should be used in single-solution electrolytic cells without diaphragm, fritless type cell. Can be used with moisture vaporizati on method(When using AQUAMICRON™ AXI or FLS in a moisture vaporization method, replenish the vaporized portion with methanol.) |
| Easy to use | Ceramic diaphragm is not used, therefore it is easy to maintain electrolytic cell in good condition. | |
