DetailsA sample is supposed to represent the ENTIRE flow. If the sample is cut from one spot only, chances are it will not be a true sample. Is the sample that is being taken, a representation of production over a period of time, like a shift sample? If it is, then for the sample to be accurate it must be made up of many smaller samples.
DetailsNo reputable concern to-day would think of attempting to determine by grab-sampling the amount of gold, silver, lead, or copper contained in an ore, and yet many buyers expect the miner to accept the results of grab-sampling in the determination of the amount of water contained in the ore, forgetting that accurate results are just as necessary ...
