Tim, that's funny....in a morbid sort of way. Calling a bomb squad to get rid of a vial of picric acid. I, too, am an analytical chemist--with a specialty in the really arcane field of ultrapure water. We use colorimetry every day.
I've attempted more than one on this forum to explain the difference between precision and accuracy, and the meaning of detection limit and limit of precision. Personally, I think results should be reported as the number with the +/- precision value added. I know, it would be confusing and upset a lot of people--but--it would be the true correct report.
Anyway, to the OP: not to worry. As long as you have the <, you're good. Carry on.
When I've had to explain it I used that classic diagram of 4 targets with bullet holes:
Holes tightly grouped in bullseye: gun accurate & precise
Holes tightly grouped outside bullseye: gun not accurate but precise
Holes poorly grouped in bullseye: gun accurate but not precise
Holes poorly grouped outside bullseye: gun neither accurate nor precise
Then you go on to give examples of the combos with a digital scale and a known weight.
The confusion of course comes from the non-scientific precise
meaning accuracy of expression or detail.
