Ensuring Accurate and Precise Measurements in Environmental Chemistry

Created using ChatSlide

This lecture introduces the essential concepts of accuracy and precision, specifically tailored for chemistry education. We will explore systematic and random error types, analysing their causes and impacts on measurement reliability. Practical examples, such as arsenic measurement and microplastics counting, will illustrate these principles. Techniques for assessing accuracy (via % recovery) and precision (RSD) will be covered, alongside real-world strategies to enhance measurement...
