30 Seconds of Info from Ian Glacken – Director of Geology: Blanks should never be inserted at regular intervals within the sample stream

Blanks should never be inserted at regular intervals within the sample stream:  It is always much more easy for automation of the QAQC process that blanks are inserted at regular intervals, but this is not optimal and is in fact a waste of money.  Since blanks are designed to test contamination between samples due to the preparation equipment, the best ‘value’ from a blank is to be placed within or immediately after a high-grade zone (if these can be identified a priori).  This is a hassle for system design but arguably the value outweighs the cost.
