Product Snapshot

Why Ash Content Testing Matters

Ash testing helps laboratories:

• Determine mineral composition

• Identify contamination or impurities

• Verify product quality and consistency

• Support regulatory compliance

• Validate formulation accuracy

What Is This Product Used For?

Labmate LMACT-A102 is used to determine ash percentage by burning off organic matter and measuring the remaining inorganic residue.

Applications:

• Food mineral analysis

• Petroleum sulfated ash testing

• Pharmaceutical residue analysis

• Polymer filler evaluation

• Environmental sample testing

How Does Labmate LMACT-A102 Work?

Simple Answer:

It burns the sample and weighs the remaining ash.

Step-by-step process:

1. Sample placed in crucible

2. Heated in chamber with controlled temperature

3. Organic matter decomposes

4. Inorganic residue remains

5. Residue weighed to calculate ash percentage

Core Functional Capabilities

• High-temperature combustion chamber

• Programmable heating profiles

• Uniform heat distribution

• Multi-sample batch processing

• Gravimetric analysis workflow

• Digital interface for monitoring

Frequently Asked Questions 

Q1. What does an ash content tester measure?

      It measures inorganic residue remaining after combustion.

Q2. Why is ash content important?

      It indicates mineral content, purity, and contamination levels.

Q3. What temperature is used for ash testing?

       Typically 500°C–600°C, but can reach up to 1000°C depending on method.

Q4. How is the ash percentage calculated?

       By dividing residue weight by original sample weight and multiplying by 100.

Q5. How long does an ash test take?

       Usually 1–4 hours depending on sample and method.

Q6. What is the difference between an ash tester and furnace?

       An ash tester includes controlled measurement workflow, while a furnace mainly provides heat.

Q7. What samples can be tested?

       Food, petroleum, pharmaceuticals, polymers, and environmental samples.

Q8. Can multiple samples be tested at once?
