Product Overview
The Platinum Cobalt Color Standard (Pt-Co/Hazen) is a highly stable, analytical-grade solution designed for accurate color measurement in laboratory and industrial settings. This reference standard follows the Hazen color scale (Haz 0), providing a consistent baseline for comparing the color intensity of liquids, particularly in water treatment, pharmaceuticals, and chemical manufacturing. The platinum-cobalt complex ensures long-term stability and reproducibility, making it indispensable for quality control processes where color consistency is critical. The solution is pre-diluted to a standardized concentration, eliminating the need for additional preparation and reducing potential errors. Its compatibility with spectrophotometric and visual comparison methods ensures versatility across different testing protocols. The analytical grade purity guarantees minimal interference from contaminants, ensuring reliable results even in trace-level applications. This standard is particularly valuable in industries where color deviations can indicate impurities or degradation, such as in petroleum products, beverages, and wastewater analysis. The 1000 ml packaging provides an optimal balance between cost-efficiency and usage frequency, reducing the need for frequent replenishment while maintaining solution integrity throughout its shelf life.
FAQs
1. What is the shelf life of this platinum cobalt color standard?
The solution remains stable for 24 months when stored in its original container at room temperature, protected from direct sunlight and moisture. Regular recalibration is recommended if used for critical applications.
2. Can this standard be used with automated colorimeters?
Yes, it is fully compatible with most spectrophotometric and automated color measurement systems that support the Pt-Co/Hazen scale. Always verify instrument specifications for optimal wavelength settings.
3. How does this compare to APHA color standards?
The Pt-Co/Hazen scale is chemically identical to the APHA scale, with Hazen 0 corresponding to APHA 0. The standards are interchangeable for most applications, though some industries prefer one terminology over the other.
4. What precautions should be taken during handling?
While non-toxic, the solution should be handled with standard lab safety practices. Use nitrile gloves to prevent contamination, and avoid contact with strong oxidizing agents that could alter the color stability.
5. Is this standard traceable to national metrology institutes?
The solution is manufactured under ISO-guided processes and can be provided with a certificate of analysis upon request, though it is not individually certified by NMI labs. For NIST-traceable standards, specialized calibration services may be required.
