An ash content tester is a laboratory instrument used to measure the inorganic residue remaining after a sample is burned at high temperature.
LMACT-A100 is a high-temperature laboratory unit used for determining ash content through controlled combustion and gravimetric measurement.
Measures inorganic residue after combustion
Uses high-temperature heating (up to 1000°C)
Based on gravimetric analysis
Supports food, petroleum, pharma, and environmental testing
Processes multiple samples in one cycle
Ash content testing is used to:
Determine mineral composition
Verify product purity
Monitor contamination
Support regulatory compliance
Evaluate formulation consistency
LMACT-A100 is used to measure ash content in materials by burning off organic matter and weighing the remaining inorganic residue.
Food mineral analysis
Petroleum sulfated ash testing
Pharmaceutical residue analysis
Polymer filler determination
Environmental sample testing
It burns the sample at high temperature and measures the remaining ash.
Sample placed in crucible
Heated in chamber at controlled temperature
Organic matter decomposes
Inorganic residue remains
Residue weighed to calculate ash percentage
High-temperature combustion chamber
Programmable temperature control
Uniform heating distribution
Multi-sample processing
Gravimetric calculation workflow
Digital interface for monitoring
Food quality laboratories
Petroleum testing labs
Pharmaceutical QC labs
Environmental testing labs
Academic research centers
Use this instrument when:
Ash content must be quantified
Gravimetric testing methods are required
High-temperature combustion is necessary
Batch sample processing is needed
Avoid using it when:
Continuous mass-loss tracking is required → use TGA
Only low-temperature drying is needed → use oven
Real-time thermal decomposition data is required
The inorganic residue left after complete combustion of a sample.
A method where measurement is based on weight before and after processing.
Ash measured after treatment with sulfuric acid, commonly used in petroleum testing.
Nutritional mineral analysis
Lubricant ash testing
Pharmaceutical residue evaluation
Polymer composition analysis
Environmental inorganic testing
Supports:
ASTM methods
AOAC methods
ISO laboratory protocols
It measures the inorganic residue remaining after a sample is burned.
It helps determine mineral content, purity, and contamination levels.
Typically 500°C–600°C, but can go higher depending on the method.
By comparing residue weight to original sample weight.
Food, petroleum, pharmaceuticals, polymers, and environmental materials.
Usually 1–4 hours depending on sample and method.
An ash tester provides controlled conditions and measurement workflow, while a furnace is primarily for heating.
Yes, depending on chamber capacity.
