A disputed cargo at a British Columbia bulk terminal rarely begins with a geology problem. It begins with an ash or moisture figure the buyer's laboratory refuses to accept. Contested proximate data costs Canadian shippers real money.
A thermogravimetric analyzer in Canada settles that argument by measuring moisture, ash, volatile matter, and loss on ignition under programmed heating. Qualitest supplies TGA systems for both production labs and research groups.
Solid Fuel Testing Across Canada's Export Supply Chain
Canadian mines produced 42.6 million tonnes of coal in 2024, and British Columbia accounts for roughly 69 percent of that tonnage. Over 95 percent of BC output is steelmaking coal rather than thermal grades.
Glencore's Elk Valley Resources operates four steelmaking coal mines in southeastern British Columbia. Consequently, every cargo bound for buyers in Japan, South Korea, and China carries documented moisture, ash, and volatile matter values.
Wood pellets face equally close scrutiny. Canadian producers ship to the European Union, Japan, and South Korea, where offtake contracts price directly against ash and moisture specifications.
Asian utility demand has reshaped that trade, and the Wood Pellet Association of Canada tracks new capacity coming online across British Columbia, Alberta, and Quebec. Each new line adds another quality-control bench that must report defensible numbers.
Traditional proximate testing ties up a drying oven, a muffle furnace, and an analyst juggling hot crucibles. Automated thermogravimetric instruments consolidate that sequence into one programmed run with internal weighing.
The QualiTGA 1200 determines moisture, ash, volatile matter, and loss on ignition, then calculates fixed carbon and calorific value. It handles coal, coke, solid waste, and biomass fuels.
Standards listed for this analyzer line include:
- ISO 11722 and ASTM D3173: moisture in the analysis sample of coal and coke
- ISO 1171 and ASTM D3174: ash content determination
- ISO 562 and ASTM D3175: volatile matter determination
- ASTM D7582: proximate analysis by macro thermogravimetric analysis
Matching a Thermogravimetric Analyzer in Canada to Your Workload
Furnace architecture and batch size drive the decision more than headline temperature range. All four models reach 1000 degrees C, so the real question is how many samples cross your bench each shift.
| Model | Furnace Layout | Batch Capacity | Typical Use |
|---|
| QualiTGA 6000A | Single furnace | 19 samples plus blank | Moisture and ash programs |
| QualiTGA 6000 | Dual furnaces | Up to 25 samples plus blank | High-volume terminal labs |
| QualiTGA 1200 | Dual furnaces | 54 samples within 8 hours | Mixed fuel and LOI work |
| QualiTGA 1000C | Analytical furnace | Single sample | Polymer and R&D analysis |
Sample weight on the macro line runs 0.5 to 1.1 g with 0.02 percent RSD precision. The QualiTGA 6000A suits labs that report moisture and ash but outsource volatile matter.
Utility planning deserves early attention. The QualiTGA 1200 draws up to 4.5 kW and runs on compressed air alone, while the QualiTGA 6000 splits its load across two furnaces. Remote mine-site labs in the Rockies should confirm voltage before shipment.
Cement, Clinker, and Fly Ash Carbon Control
Canadian cement producers blend supplementary cementitious materials to lower clinker factor and reduce emissions. Residual carbon in fly ash interferes with air entrainment, which matters for concrete exposed to prairie and Atlantic freeze-thaw cycling.
CSA A3001 governs cementitious materials used in Canadian concrete, and loss on ignition sits among the acceptance criteria plants monitor. Loss on ignition measures the mass a sample sheds when heated to a fixed temperature.
The macro analyzers determine carbon content in fly ash and clinker directly. The QualiTGA 6000 splits moisture and ash into one furnace and volatile matter into a second, so a materials lab can run parallel batches without queuing.
Polymer and Composite Deformulation in Ontario and Quebec
Ontario and Quebec host most of Canada's plastics processing and automotive parts manufacturing. Deformulation work in those plants needs microgram resolution rather than bulk crucibles and gram-scale loads.
The QualiTGA 1000C uses an electromagnetic null-point balance with 0.01 mg resolution, extendable to 1 microgram. Automated nitrogen and oxygen switching separates volatiles, polymer, carbon black, and inorganic filler within a single run.
Its supported test methods cover compositional analysis, rubber formulation, plastics thermogravimetry, and decomposition kinetics:
- ASTM E1131: compositional analysis by thermogravimetry
- ASTM D6370: rubber compositional analysis
- ISO 11358 Parts 1 to 3: thermogravimetry of polymers
- ASTM E1641: thermal decomposition kinetics
Heating rates span 0.1 to 80 degrees C per minute, and the first-derivative curve resolves overlapping degradation steps into distinct peaks.
Plan Your Lab Capacity With Qualitest
Throughput shapes this purchase more than any single specification. A terminal laboratory clearing three batches a day has entirely different requirements than a research group profiling one composite at a time.
Qualitest North America supports Canadian laboratories from Richmond Hill, Ontario, with configuration guidance, calibration documentation, and site utility planning covering gas supply and power draw. Labs pursuing ISO/IEC 17025 accreditation through the Standards Council of Canada need that documentation from installation onward.
Share your sample types, daily volume, and reporting standards, then contact Qualitest for a configuration recommendation. Call +1 905 944 9825, fax +1 905 944 0304, or email sales@qualitest-inc.com. Our office sits at 70 East Beaver Creek Rd., #9, Richmond Hill, Ontario L4B 3B2.
