17 Reagents, Reference Materials & Laboratory Chemicals Validation through comparative studies
Anton Paar conducted a series of comparative measurements to validate the performance of its dual-parameter systems against traditional titration. For 50% sulphuric acid, the system measured an average concentration of 47.88% with a standard deviation of 0.01%, while titration gave 47.89% with a deviation of 0.07%. For high-purity samples, such as 96% sulphuric acid, the difference in precision became more signifi cant. Similarly, for oleum samples at 20% and 50% concentrations, the dual- parameter system outperformed titration in repeatability and accuracy.
These results highlight not only the high precision of Anton Paar’s systems but also their consistency and reliability. For process engineers, this means fewer recalibrations, reduced waste, and better control over fi nal product quality.
Adaptability and integration in industrial environments
Anton Paar’s measurement solutions are designed with fl exibility in mind. They are available in multiple confi gurations, from portable lab instruments to fully integrated inline solutions for continuous monitoring. Integration with process control systems (PCS) and manufacturing execution systems (MES) is seamless. Instruments can transmit data in real-time via analogue or digital interfaces and can be remotely confi gured or monitored. This enables users to automate their quality control processes and reduce manual intervention, thereby minimising human error and increasing overall productivity.
Focus on safety: Materials, handling, and protocols
Working with strong acids like sulphuric acid and oleum requires rigorous safety protocols. Anton Paar addresses this need by selecting chemically resistant materials such as glass, Viton, and PTFE for all wetted parts. The instruments are constructed to withstand corrosion, high temperatures, and aggressive cleaning agents.
Clear guidelines are provided for sample handling, cleaning, and maintenance. For instance, dilution must always be performed by adding acid to water slowly – never the reverse – due to the exothermic reaction. Additionally, a structured cleaning sequence is recommended, starting with a weaker acid before moving to water, to prevent sudden reactions and preserve the longevity of the measuring cell.
Supporting a wide range of industries
Anton Paar’s chemical measurement systems are employed across a diverse range of sectors. In the fertiliser industry, they help control the exact concentration of sulphuric acid used in phosphate production, ensuring consistent nutrient content in the fi nal product. In battery manufacturing, precise control of acid concentrations enhances battery performance and longevity.
In the pharmaceutical and food sectors, where regulatory compliance and purity are paramount, Anton Paar’s systems deliver results that meet the highest standards. In petrochemical refi neries and metal treatment plants, real-time monitoring of acid strength ensures effi cient reactions and minimises environmental impact.
Beyond sulphuric acid: A platform for broader applications
While this article focuses on sulphuric acid and oleum, Anton Paar’s technology is applicable to a wide variety of chemicals. The same measurement principles can be adapted for nitric acid, phosphoric acid, hydrochloric acid, and others. Whether in research labs, specialty chemical plants, or large-scale production facilities, the platform offers a scalable and adaptable solution for precise liquid analysis.
The ability to create custom calibration profi les, automate workfl ows, and integrate with laboratory information management systems (LIMS) further expands the usability of these instruments. As industries move toward smart manufacturing and Industry 4.0, such systems provide a solid foundation for data-driven decision-making and continuous improvement.
Conclusion: Measurement as a strategic asset
In modern chemical and process industries, measurement is not merely a technical function – it is a strategic capability. Companies that can measure more accurately and respond more quickly to deviations gain a competitive edge in quality, safety, and effi ciency.
Anton Paar’s dual-parameter chemical measurement systems embody this philosophy. With cutting-edge technology, robust engineering, and user-centric design, these instruments deliver unmatched value across the board. For any operation that depends on the accurate quantifi cation of aggressive chemicals, investing in Anton Paar’s solutions is a step toward smarter, safer, and more effi cient production.
With a commitment to innovation and a global support network, Anton Paar continues to shape the future of chemical measurement – one precise reading at a time.
