Course: sampling calculation with ECHANT software

 Sampling is a major concern for processing plants. Samples must be representative and accurate to give a good picture of plant performance and also enable optimized process analysis. When dealing with heterogeneous materials, minimize sampling and measurement errors are complex tasks. Sampling calculation course will bring you the key to design reliable sampling protocols and campaigns. Ready to better monitor plant processes and maximize output with our ECHANT software?

Better monitor your industrial process with sampling

When sampling solid materials in processing plants, there is inevitably a difference between what is observed on the sample and what would have been observed on the whole material (i.e. the lot). This heterogeneity is responsible for the generation of the main sampling error, known as the Fundamental Sampling Error (FSE).

Based on Pierre Gy’s sampling theory, you will learn to calculate the Fundamental Sampling Error with ECHANT software and design reliable sampling protocols for any solid material.
