Read the Automatic Buret Instruction Manual before proceeding. A

to 20 parts per million of Sulfite (SO

NOTE: Sulfite standards deteriorate quickly and must be tested
immediately. To improve stability, Standard Methods (17th Edition, 4500
- SO

EDTA/100 mL Distilled Water) per 100 mL sample. The sample still
must be tested immediately and taken with minimal air contact.
