I need a graph or table or any info with reference to use of stability of ozone in water temp, dosing relation with time.

I use of a uv spectrophotometer and then I see in 190nm I have negative absorption.

reference is water and nothing added to water except uses ozone process.

note: I use of quartz cell, cell is completely clean, several time measurement, several time set base line and don't use of auto zero.
