Residue on Ignition (ROI) testing is a critical analytical method used in the pharmaceutical, food, chemical, and advanced materials industries to determine inorganic impurities and product purity. Traditionally, this test has relied heavily on manual operations, making the process time-consuming, labor-intensive, and susceptible to operator variability.
Leveraging more than 14 years of dedicated research and development, Labthink has introduced the C860 Integrated Residue on Ignition Testing System, a fully automated solution designed to streamline the entire testing workflow. From weighing and acid addition to ignition, cooling, reweighing, and constant-weight determination, the C860MH automates every critical step, significantly improving laboratory efficiency and data reliability.
At the heart of the system is an intelligent robotic handling mechanism that automatically transfers crucibles between the analytical balance and the muffle furnace. This eliminates manual handling, reduces operator workload, and minimizes potential sources of error. The system also integrates automatic weighing, automatic constant-weight judgment, and a liquid cooling module, ensuring consistent and repeatable test results.
To meet different laboratory requirements, Labthink offers two models. The C860H features 36 test positions and a balance resolution of 0.01 mg, making it ideal for high-throughput and high-precision applications. The C860M provides 16 test positions with a standard balance resolution of 0.1 mg, offering an excellent balance between automation and investment cost.
Compared with conventional systems on the market, the C860 series delivers a higher level of automation. While many traditional solutions still require manual acid addition, manual crucible transfer, and weighing under elevated temperatures, the C860 series utilizes independent room-temperature weighing, automatic crucible transfer, and optional automatic acid dispensing. These features not only improve operational efficiency but also enhance safety and measurement stability.
The system can also be configured with 21 CFR Part 11 compliance and GMP-oriented software solutions, supporting electronic records, audit trails, and data integrity requirements commonly found in regulated pharmaceutical environments.
As laboratories continue to pursue automation, digitalization, and higher testing efficiency, residue on ignition testing is evolving beyond traditional manual methods. The Labthink C860 Integrated Residue on Ignition Testing System is more than just an instrument, it is a comprehensive automation platform that helps laboratories improve productivity, reduce human error, and ensure reliable, traceable results throughout the testing process.
