FAQs
1. What is the exact melting range of this Anthraquinone standard?
The certified melting range is 283-286°C, with each batch tested to ensure consistency within this narrow temperature window.
2. Can this standard be reused for multiple calibration tests?
While technically possible, we recommend using fresh samples for each calibration to maintain accuracy, as repeated heating may cause slight degradation.
3. How should this standard be stored for long-term use?
Store in a tightly sealed container at room temperature, protected from light and moisture to maintain its calibration properties.
4. Is this standard compatible with automated melting point apparatus?
Yes, the uniform particle size and consistent melting behavior make it suitable for both manual and automated melting point instruments.
5. What alternatives exist for higher temperature calibration?
For temperatures above 300°C, consider standards like benzoic acid (122°C) for lower ranges or sulfanilamide (165°C) for mid-range calibration needs.
