REQUIRED CALIBRATION SUPPLIES
The number of standards required for the calibration procedure depends on whether
running a single-point or multi-point calibration. Standards vials are inserted into the iOS
System as prompted by the Analyzer’s on-screen instructions.
A single-point calibration should require approximately one hour to complete, and multi-
point calibration should require approximately two hours to complete.
NOTE: For all calibration and verification procedures use only
Sievers standards purchased from SUEZ.
To purchase standards, contact Customer Care or your local service provider.
Standards sets for calibration and verification can be purchased individually, or as vial
sets for use with a Super iOS System. All standards are provided in 40-mL and 30-mL
vials. Standards sets for validation can be purchased individually, or as a combined
Validation Set.
Standards used in each of the system protocols are shown in Table 6-1 through Table 6-
3. Standards concentrations are shown in ppm and ppb. Note that 1 ppm = 1 mg C/L,
and 1 ppb = 1 µg C/L.
