1. Fill three test tubes (0843) to the 10 mL line with sample water.
Insert two tubes as blanks in the Axial Reader.
2. Use the plain pipet (0357) to add 10 drops of Nitrite Nitrogen
Reagent A (7423) to third test tube.
3. Use the 1.0 mL pipet (0354) to add 1.0 mL of *Nitrite Nitrogen
Reagent B (7424). Cap and invert to mix. Allow to stand for 30 to
45 seconds.
4. Use the 0.15g spoon (0727) to add one level measure (avoid any
excess) of Nitrite Nitrogen Reagent C-R. Cap and mix. Allow to
stand for 3 minutes. A pink color indicates the presence of nitrite.
5. Remove cap and insert tube in the Axial Reader comparator. Follow
the Axial Reader instructions to compare the sample color with the
standards. Record result as ppm Nitrite (NO
