This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. This course is designed to provide participants with a fundamental overview of Maintain QMI (Analysers & Sample Systems). It covers the QMI analysers and sample systems including the basics of quality measurement instruments (QMI) in the context of process systems; the different types of analysers and their roles in maintaining process quality; the purpose and function of analysers in process systems using process and instrumentation diagrams (P&IDs) and how these instruments integrate into the larger process system; the components of analyser sample systems and their functions and importance in the overall system. Further, the course will also discuss the procedure on how to obtain, interpret and use relevant drawings and specification data for testing and diagnosing faults in QMI equipment and sample systems; and the safety protocols and isolation techniques focusing on how to safely isolate and depressurize analysers in preparation for maintenance activities. During this interactive course, participants will learn the routine maintenance procedures covering standard maintenance protocols for QMI analysers and sample systems including scheduled checks and cleaning processes; the advanced troubleshooting techniques and methods for identifying and rectifying common issues in analyser systems; the calibration and validation analysers; the techniques and best practices for calibrating analysers to ensure accuracy and reliability; the performance testing and analysis and how to conduct performance tests on QMI equipment; and interpreting results to assess system health and efficiency.
