Labmate LMACT-A101 Ash Content Tester is a laboratory instrument used to determine inorganic residue (ash content) by combusting samples at controlled high temperatures and measuring the remaining mineral content. It is commonly used in food, petroleum, pharmaceutical, and environmental laboratories for gravimetric analysis.
Ash content refers to the inorganic residue remaining after complete combustion of organic material. It represents mineral composition and is expressed as a percentage of the original sample weight.
The ash determination process follows a structured gravimetric workflow:
A sample is weighed and placed in a crucible
The crucible is inserted into the combustion chamber
A programmed temperature cycle heats the sample
Organic material is oxidized
Inorganic residue remains
The crucible is cooled in a desiccator
Final weight is measured to calculate ash percentage
This process supports repeatable laboratory analysis under controlled temperature conditions.
Labmate LMACT-A101 is used for quantitative ash determination across multiple laboratory applications:
Food mineral content analysis
Sulfated ash testing in petroleum products
Pharmaceutical residue evaluation
Polymer filler and additive analysis
Environmental sample testing (soil, sludge)
Academic material composition studies
Ash testing is important because it:
Measures total mineral composition
Supports regulatory compliance (ASTM, AOAC, ISO)
Helps verify product purity and composition
Identifies contamination or residue
Supports quality control documentation
High-temperature combustion up to 1000°C
Digital programmable temperature control
Uniform heat distribution inside chamber
Multi-crucible batch processing

Q1. What does Labmate LMACT-A101 measure?
It measures inorganic residue (ash content) after high-temperature combustion of a sample.
Q2. What temperature is used for ash testing?
Most methods use 500°C to 600°C, though some require up to 1000°C depending on the material.
Q3. What samples can be tested?
Food, petroleum, pharmaceuticals, polymers, and environmental samples.
Q4. How is the ash percentage calculated?
Ash % = (residue weight ÷ original sample weight) × 100.
Q5. Is it suitable for pharmaceutical testing?
Yes, it is used for residue and excipient evaluation in pharmaceutical laboratories.
Q6. How long does testing take?
Typically 1–4 hours depending on sample type and method.
