6.1 Reagents
BioTector TOC analyzer uses the following reagents:
I. Acid: 6.0 N Sulfuric Acid (H
2
SO
4
) Reagent containing 350 mg/l Manganese Sulfate Monohydrate
II. Base: 4.0 N Sodium Hydroxide (NaOH) Reagent
Reagents should not contain high levels of organics, nitrates and phosphates. Ideally, the level of organics,
nitrates and phosphates should be less than 100

g/l (ppb) in the deionized water used to prepare TOC
analyzer reagents.
Acid and Base reagents are stable up to 1 year. The reagents must be stored in a safe and secure location,
where the temperature does not drop below 2°C, in compliance with the local regulations. Table 6 below
summarizes the total days each BioTector TOC Analyzer reagent lasts at various system configurations:
