Some time ago I sent in some batches of CS (27 VDC method) for total silver
and resistivity measurements at an environmental lab. I have plotted
resistivity against silver concentration, as shown on the attached Excel
spreadsheet.

Three of the readings make a fairly straight line. However, the low
concentration sample (9.12 ppm vs 59,500) is way off. Anyone have any
thoughts as to why this might be??
