Can zero be quantified?
Quantifying zero.
Zero is a number that cannot be measured by any instrument or measurement technique.

For example, the zero mark on a ruler has a width to it. If one wanted to measure zero seconds, starting and immediately stopping a stopwatch would still result in a greater than zero time measurement. The same can be said for measuring zero concentration or zero conductivity.

For this reason, every instrument and measurement technique will have a defined detection limit, below which the existence of a parameter cannot be determined.

The following article provides more information on Detection Limits:

What are the definitions and differences of common Detection and Quantification Limits?
