1. What is Moisture and Volatile Matter?

Definition: Moisture and Volatile Matter is the loss in mass of the sample on heating at 105 ± 1°C under operating conditions specified.

Purpose: This measurement is crucial in quality control for various materials, especially in food, pharmaceutical, and chemical industries.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ MVM = \frac{W1}{W2} \times 100 \]

Where:

Explanation: The dry loss is divided by the original material weight and multiplied by 100 to get the percentage.

3. Importance of MVM Measurement

Details: Proper measurement ensures product quality, shelf life stability, and compliance with industry standards.

4. Using the Calculator

Tips: Enter the dry loss and original material weight in kilograms. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What temperature should be used for drying?
A: Standard method uses 105 ± 1°C unless otherwise specified by industry standards.

Q2: How long should the sample be dried?
A: Typically until constant weight is achieved, usually 3-4 hours.

Q3: What's considered a normal MVM range?
A: This varies by material but typically 5-15% for many organic materials.

Q4: Does this include all volatile components?
A: Yes, this method measures both moisture and other volatile matter.

Q5: How precise should measurements be?
A: For accurate results, measure to at least 0.0001 kg (0.1 g) precision.
