Interfering substance
Interference level Metals Some metals, especially copper, catalyze the oxidation of sulfite to sulfate. Immediately add TK - 14 ::: RXSOL-62-5503-003 powder for each liter of sample during sample collection to prevent the interference.
Nitrite Reacts with sulfite and causes low results.
Organic compounds Oxidizable organic compounds can cause high results.
Oxidizable compounds Cause high results.
Sulfide Causes high results.
Samples must be analyzed immediately after collection and cannot be preserved for later analysis.
Let the sample temperature decrease to 50 °C (122 °F) or less before analysis.
Sulfite reacts quickly with oxygen in the air. Shaking or swirling the sample causes low results. Prevent agitation of the sample during the procedure.
Review safety chemical handling procedure. Use the recommended personal protective equipment. Dispose of reacted solutions according to local, state and federal regulations.
