If you have performed a reagent flush in the last 8 hours, click No to skip the flush and
proceed to Step 6.
6. When the flush is complete, click OK to continue. Remove the protective cap from the
standards vials, and avoid touching the septa to protect against introducing foreign
particles.
At this point, the prompts on the Analyzer’s display screen will help guide you through the
calibration process.
7. Insert the Calibration Blank into the IOS System, and press Next.
8. When prompted, remove the Calibration Blank from the IOS System, insert the 1 ppm TOC
Calibration Standard (as KHP), and press Next.
9. When prompted, remove the 1 ppm TOC Calibration Standard (as KHP) from the IOS
System, insert the 5 ppm TOC Calibration Standard (as KHP), and press Next.
10. When prompted, remove the 5 ppm TOC Calibration Standard (as KHP) from the IOS
System, insert the 10 ppm TOC Calibration Standard (as KHP), and press Next.
11. When prompted, remove the 10 ppm TOC Calibration Standard (as KHP) from the IOS
System, insert the 25 ppm TOC Calibration Standard (as KHP), and press Next.
12. When prompted, remove the 25 ppm TOC Calibration Standard (as KHP) from the IOS
System, insert the 50 ppm TOC Calibration Standard (as KHP), and press Next.
13. After the 50 ppm TOC Calibration Standard (as KHP) has been analyzed, you will be
prompted to enter the IC standards. Remove the 50 ppm TOC Calibration Standard (as KHP)
from the IOS System, insert the 1 ppm IC Calibration Standard (as Na
2
CO
3
), and press Next.
14. When prompted, remove the 1 ppm IC Calibration Standard (as Na
2
CO
3
) from the IOS
System, insert the 5 ppm IC Calibration Standard (as Na
2
CO
3
), and press Next.
15. When prompted, remove the 5 ppm IC Calibration Standard from the IOS System, insert the
10 ppm IC Calibration Standard (as Na
2
CO
3
), and press Next.
16. When prompted, remove the 10 ppm IC Calibration Standard from the IOS System, insert
the 25 ppm IC Calibration Standard (as Na
2
CO
3
), and press Next.
17. When prompted, remove the 25 ppm IC Calibration Standard (as Na
2
CO
3
) from the IOS
System, insert the 50 ppm IC Calibration Standard (as Na
2
CO
3
), and press Next.
18. After the 50 ppm IC Calibration Standard (as Na
2
CO
3
) has been analyzed, the calibration
summary screen is displayed (see Figure 25 and Figure 26). Toggle between the values for
each channel by pressing the IC Data and TC Data buttons. The Analyzer indicates if the
calibration passed or failed based on the following criteria:
