Sampling and Storage
Collect samples in clean plastic or glass bottles. Samples must be analyzed
within 24 hours.
Accuracy Check
Standard Solution Method
Dissolve 1.000 gram of cyanuric acid in l liter of deionized water to make a
1000-mg/L solution. Cyanuric acid is difficult to dissolve; it may take several
hours to completely dissolve. This solution is stable for several weeks.
Dilute 3.00 mL of the 1000-mg/L solution to 100 mL with deionized water to
make a 30-mg/L solution. Prepare fresh daily.
Testing the 30-mg/L solution should give test results of about 30 mg/L
cyanuric acid.
Standard Curve Adjustment
Use the standard prepared in the Accuracy Check. Adjust the calibration curve
using the reading obtained with the 30-mg/L standard solution:
1. Touch
Options on the current program menu. Touch Adjustments & Accuracy
on the Options menu. Touch
Standard Adjust.
2. Touch On. Touch OK to accept the displayed concentration. If an alternated
concentration is used, touch the number in the
Adjust to field and enter the
actual concentration. Press
OK.
5. Fill a second sample
cell with 25 mL of sample
(the blank) and place it in
the cell holder.
6. Touch Zero.
The display will show:
0 mg/L Cyan Acid
7. Within seven minutes
after the timer beeps,
place the prepared
sample into the cell
holder.
8. Touch Read.
Results will appear in
mg/L Cyan Acid.
