Periodic Maintenance Tasks

Periodic Inspections

To ensure optimum performance of the Analyzer, inspect the following items periodically.
1. Reagent levels. Inspect the reagent and dilution water containers to ensure that there is adequate
acid, oxidizer, and dilution water to perform the analyses
according to the directions in the following section.
2. Check Standard level. Inspect the Check Standard carboy to ensure that there is adequate solution to
perform the analyses
3. Reagent, Check Standard, and dilution water tubes. Ensure that the ends of the reagent, Check
Standard, and dilution water tubes extend into their respective liquids. If the Fail Safe accessory is
installed, check the level sensors to ensure that they are operating properly.
4. Flush, if necessary. Ensure that the tubing from the reagent, Check Standard, and dilution water
containers is full of liquid, and that there are no large bubbles in those tubes. If any of the tubes contain
large bubbles, perform a Flush.
5. Check calibration. Analyze one or more Check Standards to confirm that the Analyzer is operating
properly and that its calibration is accurate

Preparing the Oxidizer Solution

The following figure shows how the strength of 30% (W/V) sodium persulfate solution decreases with time at 5
°C, 25 °C and 40 °C. These data were obtained with reagent grade sodium persulfate in low-TOC reagent water,
while the solution was stored in high-density polyethylene (HDPE) bottles of the type used with the InnovOx
Laboratory TOC Analyzer.
6.
This inspection is automatically performed by the Analyzer if the Fail Safe accessory is installed and
activated.
7.
The Analyzer can be set to automatically perform the Check Standard measurements.
