Product Overview
The platinum cobalt color standard (Pt-Co/Hazen 10) is a highly stable and precise reference solution used for determining the color intensity of liquids in laboratory and industrial applications. This standard is prepared using platinum and cobalt chlorides, which produce a consistent yellow hue that serves as a benchmark for comparing sample colors. The solution adheres to international standards such as ISO 6271 and ASTM D1209, ensuring reliability in colorimetric analysis. Its analytical-grade purity guarantees minimal interference from impurities, making it ideal for critical measurements in water treatment, chemical manufacturing, and quality control processes. The 1000 ml pack size provides sufficient volume for repeated calibrations and testing without frequent replenishment. The solution is packaged in amber glass bottles to prevent light-induced degradation, maintaining its stability over extended periods. Whether used in spectrophotometric analysis or visual comparison methods, this platinum cobalt standard delivers reproducible results, eliminating variability caused by subjective assessments. Its compatibility with standard laboratory glassware and instruments further enhances its utility in diverse testing environments.
FAQs
1. What is the shelf life of the platinum cobalt color standard?
The solution remains stable for up to 24 months when stored in its original amber glass bottle at room temperature, away from direct sunlight and moisture. Always check for precipitation or color changes before use.
2. Can this standard be used for both visual and instrumental color measurement?
Yes, the platinum cobalt color standard is designed for compatibility with both visual comparison methods (using Nessler tubes) and instrumental techniques like spectrophotometry, provided the instrument is calibrated according to ISO 6271 guidelines.
3. How does this compare to other color standards like APHA or Saybolt?
The Pt-Co/Hazen scale is specifically optimized for yellow-tinted liquids, while APHA (American Public Health Association) is nearly identical but often used in different industries. Saybolt color standards are typically used for petroleum products and measure darker hues.
4. Is this standard compatible with automated colorimeters?
Yes, the solution is formulated to work seamlessly with most automated colorimeters and spectrophotometers, though we recommend verifying the instrument’s wavelength range (typically 400–450 nm for Pt-Co measurements).
5. What precautions should be taken during handling?
While non-toxic, the solution should be handled with standard lab safety practices: wear gloves to avoid skin contact, use in a well-ventilated area, and avoid ingestion. Dispose of waste according to local chemical disposal regulations.
