Get more reliable information from true, or correct, samples. Do not be misled by specimens, which do not represent the stream from which they were mistakenly taken. Rather, true or correct samples are obtained by observing a set of rules and models developed by Pierre Gy, covering:
- Minimum Sample Mass models
- The Rules of Unbiassed Sample Extraction
- The Semivariogram
- The Safety Line
Whether you are focussed on developing better confidence in your metal accounting, or on arranging a plant survey to identify and diagnose performance opportunities, we can formulate a project tailored to your needs. We have over thirty years of practical exerience in best practice sampling.
Let Flowsheets assist you in your project with best sampling practices…..
