*Note: 1ppm = 1 mg C/L, 1ppb = 1 µg C/L
Calibration verification standards also should be purchased in a concentration that is appropriate
for your application; sets include one vial of reagent water blank and one vial each of TOC and IC in
the selected concentration. The available concentrations are shown in Table 13.
*Note: 1ppm = 1 mg C/L, 1ppb = 1 µg C/L
System suitability standards sets include the standards shown in Table 14.
*Note: 1ppm = 1 mg C/L, 1ppb = 1 µg C/L
