By using a requirement of a bare minimum depletion of 2 mg/L as well as a remaining DO of not less than one mg/L, we do not have a substantial amount of working room with which to get at the very least just one dilution which meets acceptance requirements.
The Nitrite test measures the presence of nitrites inside the urine sample. Nitrites are substances shaped because of the conversion of nitrates by selected microorganisms. Beneath ordinary conditions, urine doesn't comprise nitrites.
