30 Seconds of Sampling Information from Ian Glacken – Director of Geology
Multi-tier riffle splitters can add to sampling error: While Jones riffle splitters can give a statistically correct sample split, this is less likely with a multi-tier splitter and unlikely with a rig-mounted multi-tier riffle splitter. Things to watch out for are the flow of the sample into the splitter (even and continuous), the orientation of the splitter (centred and vertical) and of course the presence of moisture in the sample – even a small amount of water can invalidate the splitting.
