Cleaning the A10
Periodically, the detection cell in the A10 needs to be cleaned of any built-up residual organic matter. If this
build-up happens, then the displayed TOC values could be erratic or higher then previously seen.
To fix this, an autocleaning cycle is needed to oxidise any organic contaminants present in the A10 detec-
tion cell.
To perform a cleaning cycle of the A10, follow these instructions:
