Section 6 Reagents and Calibration Standards
6.1 Reagents
BioTector TOC analyzer uses following reagents:
I. Acid: 1.8 N Sulfuric Acid (H
2
SO
4
) Reagent containing 80mg/l Manganese Sulfate Monohydrate
II. Base: 1.2 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. Table 7 below summarizes the total days each BioTector
TOC Analyzer reagent lasts at various system analysis range configurations:
