The TOC Autozero protocol determines the TOC offset, which is the difference
between the IC and TC measurements with the UV lamp off. It also determines the
background conductivity curves for each channel.

interval. The TOC Autozero is recommended only if the TOC concentration in the
sample stream is 50 ppb or less.
