A Halogen Moisture Balance is a laboratory instrument used to determine moisture content by combining:
The instrument operates on the thermogravimetric principle, where moisture content is calculated based on weight loss after controlled heating.
It measures the weight of the sample before heating and the weight after moisture evaporation, then automatically calculates the percentage of moisture.
The instrument works on the Thermogravimetric Principle (Loss on Drying – LOD Method).
Moisture Content (%) = {(Initial Weight – Final Weight) ÷} ×100
Modern halogen moisture analyzers can provide accuracy up to 0.01% moisture content.
| Component | Function |
|---|---|
| Halogen Heating Element | Provides rapid, uniform infrared heating |
| Precision Analytical Balance | Detects small weight changes accurately |
| Sample Pan | Holds the sample during analysis |
| Temperature Sensor | Controls heating temperature |
| Display & Control Panel | Shows moisture %, time, temperature |
| Drying Chamber | Enclosed chamber for safe heating |
The typical operating procedure includes:
Compared to traditional oven drying, halogen moisture analyzers offer multiple benefits:
It significantly improves efficiency in Quality Control (QC) laboratories.
Halogen moisture balances are widely used in:
Understanding how a halogen moisture balance works helps improve product consistency and regulatory compliance.
| Parameter | LOD by Halogen Moisture Balance | LOD by Traditional Oven Method |
|---|---|---|
| Principle | Thermogravimetric (Infrared heating) | Hot air oven drying |
