pH Electrode and Reagent Selection
In addition to mechanical and electrical spare parts, the CA72TOC analyzer also requires regular replacement of pH electrodes and reagents to ensure measurement accuracy.
pH Electrode CPS71
CPS71 is a pH combination electrode suitable for hygienic processes, using a ceramic diaphragm and gel reference system, and can withstand high-temperature sterilization.
- Diaphragm: ceramic
- Reference system: gel (non-acrylamide), dual chamber
- Application: hygienic, aseptic processes
- Features: sterilizable, autoclavable
- Minimum conductivity: 10 μS/cm
pH Standard Solution CPY20
CPY20 is a quality buffer solution traceable to PTB and NIST standard reference materials, supplied with a calibration certificate, suitable for calibration of pH electrodes.
Stripping Reagent CAY450
CAY450 is used for stripping inorganic carbon, contains hazardous substances, and must be handled in accordance with safety regulations.
Standard Solution CAY451
CAY451 is used to prepare standard solutions, also contains hazardous substances, please handle with care.
Maintenance Precautions
When replacing spare parts, be sure to observe the following principles to ensure personnel safety and instrument performance.
- Confirm the maintenance level of the spare part; Category 2 spare parts must be replaced by personnel who have completed E+H basic training.
- Before replacement, turn off the power and gas supply, and release the pressure in the lines.
- Use original spare parts to avoid measurement deviation caused by compatibility issues.
- After replacement, perform calibration or verification to ensure the analyzer operates normally.
Frequently Asked Questions
How to determine the maintenance level of a spare part?
The spare parts list indicates Category 1 or Category 2. If not indicated, it is usually a regular spare part and can be replaced by yourself.
Can the CO2 scrubber kit be used for Parker adsorbers?
No. The Kit CO2 scrubber series (order numbers 71232256, 71232261, 71232262) is explicitly not suitable for Parker's CO2 adsorbers.
What accessories are needed for the pH electrode CPS71?
It must be used with the pH electrode cable (order number 71101602) and calibrated regularly with CPY20 standard solution.
