Its stable composition minimizes degradation over time, maintaining accuracy across multiple uses. The solution is pre-mixed and ready for immediate use, reducing preparation time while adhering to stringent quality control protocols. Compatible with most standard COD testing equipment, this calibration fluid is ideal for environmental monitoring, wastewater treatment analysis, and industrial process control. The 500 ml pack size provides sufficient volume for routine calibration without excessive waste. Each batch undergoes rigorous testing to verify concentration accuracy, with traceable certification documentation included. The solution’s chemical stability ensures long shelf life when stored under recommended conditions, making it a cost-effective choice for laboratories requiring frequent COD measurements.
FAQs
1. What is the shelf life of this COD calibration standard?
When stored unopened at room temperature away from direct sunlight, this standard maintains its accuracy for 12 months from the date of manufacture. Always check the expiration date on the label.
2. Can this standard be used with all COD analyzers?
The 1000 mg/L concentration is compatible with most standard COD analyzers. However, verify your equipment’s specific calibration requirements as some specialized instruments may need different concentration ranges.
3. How should I store this calibration solution after opening?
After opening, tightly recap the bottle and store it in a cool, dark place between 15-25°C. Avoid temperature fluctuations and exposure to moisture to prevent concentration changes.
4. What certification comes with this COD standard?
Each batch includes a certificate of analysis documenting the exact concentration, traceability to NIST standards, and quality control test results performed during manufacturing.
5. Is this standard suitable for field testing applications?
While primarily designed for laboratory use, the solution can be used in field testing provided proper storage conditions are maintained during transport and the testing environment meets standard laboratory requirements.
