Preparing The Acid; Adding The Dilution Water; Performing A Flush - GE Sievers InnovOx Operation And Maintenance Manual

Chapter 8: Maintenance
Disposal of solid oxidizer should be performed as specified in the appropriate MSDS. For oxidizer as a solid, see
DIN 68050 Sodium Persulfate. For oxidizer as a solution, refer to DIN 68450 Sodium Persulfate, 30% Solution. You
can find copies of these DINs in the Library on our website at www.geinstruments.com.

Preparing the Acid

The InnovOx On-Line TOC Analyzer is designed to operate with either of two different acids: 6 M phosphoric acid
(H PO ) and 3M hydrochloric acid (HCl). Phosphoric acid is preferred where salts in the sample will not form
3 4
precipitates in the acid due to the presence of the phosphate anions. If precipitate formation is problem, use 3M
hydrochloric acid.
To prepare the Acid
Transfer the acid into the Acid carboy, and insert the tube assembly into the carboy.

Adding the Dilution Water

Fill the "Dilution Water" 19 L (5 gal) carboy with deionized water or the best-quality water available to you.

Performing a Flush

When installing new reagents, perform a flush to clear the tubing of bubbles and old solution.
To perform a flush
1. Select the Maintenance tab.
2. Press the Flush Reagents button.
3. Select the flush you want to perform:
• Flush Acid: Flushes the Acid.
• Flush Oxid(izer): Flushes the Oxidizer.
• Flush Dilution (Water): Flushes the Dilution Water.
• Flush Check Standard: Flushes the Check Standard.
N :
The Check Standard must be the Enabled state.
OTE
• Flush All: Flushes the Acid, Oxidizer, Check Standard, and Dilution Water.
N :
The Check Standard must be the Enabled state.
