C860H Integrated Residue on Ignition Testing System

C860H Integrated Residue-on-Ignition Testing System is based on the gravimetric method and designed and manufactured in accordance with pharmacopoeias and testing standards for pharmaceutical packaging materials, chemical reagents, and food, etc. It is suitable for the determination of residue on ignition and ash content in pharmaceuticals, pharmaceutical packaging materials, food, and food contact materials, as well as residue on ignition in chemical reagents.

Product Features^{Note 1}

Precise, Traceable, and Convenient Measurement

• Dual-chamber independent design achieves true separation of ignition and weighing, avoiding the influence of high temperatures on the balance.
• German-imported touch-screen electronic balance with repeatability up to 0.05 mg.
• Visualized balance design and traceable data.
• Internal calibration balance for quick disassembly and easy measurement.

Safe and Compliant: Standardized Processes

• Integrated design, combining the traditional muffle furnace, dryer, and balance in one.
• Testing procedures strictly adhere to multi-national pharmacopoeias, ISO and GB standards.
• Rapid liquid-cooling system achieves true room-temperature weighing.
• Automatic timed and quantitative sulfuric acid fill (optional).
• Equipped with various sensors and intelligent audible and visual alerts for safer operation.

Intelligent and Efficient: Fully Automated Process

• Equipped with fully automatic gripper that can mimic manual weighing of 36 test cups.
• Ignition, cooling, drying, and room temperature weighing are fully automatic and require no human intervention.
• 12.1" medical-grade touchscreen allows the instrument host to operate independently of a computer.
• The instrument host features a desktop design, saving space and adapting to various laboratory layouts.

Powerful Control System

• Embedded network port for remote control, data transmission, and upgrades.
• Professional computer software complies with GMP requirements for data traceability and 21 CFR Part 11.
• Multi-level user access control with configurable permissions.
• Electronic signature designed in accordance with 21 CFR Part 11.

Testing Principle

Take 1.0–2.0 g or a specified weight of sample and place it in a test cup that has been ignited to constant weight. Weigh accurately, slowly ignite until it is completely carbonized, and cool down. Unless otherwise specified, add 0.5–1 mL of sulfuric acid to moisten the sample. Heat at a low temperature until the sulfuric acid vapor is completely removed. Then ignite at 700–800 °C to completely ash it. Transfer it to a dryer, let it cool, weigh accurately, and then ignite it again at 700–800 °C to constant weight to obtain the residue on ignition.
