Product Overview

This Specpure® dichromate standard solution delivers exceptional purity and consistency for ion chromatography applications, ensuring accurate quantification of chromium (Cr) in environmental, industrial, and research samples. Formulated at a precise 1000µg/ml concentration, the solution is prepared from high-purity dichromate (Cr₂O₇²⁻) and stabilized to prevent degradation, offering long-term reliability in analytical workflows. The Specpure® grade guarantees minimal interference from trace impurities, making it suitable for demanding analytical techniques where precision is critical. Each batch undergoes rigorous quality control to meet international standards, with certification documentation provided for traceability. The solution is compatible with most HPLC and IC systems, eliminating the need for additional calibration adjustments. Its stable shelf life and ready-to-use format reduce preparation time, enhancing lab efficiency. Whether used for routine testing or high-sensitivity research, this standard ensures reproducible results, minimizing variability between analyses. The packaging in amber glass bottles protects against light-induced degradation, preserving integrity until use.

FAQs

1. What is the shelf life of this dichromate standard solution?

The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature in its original packaging. Once opened, use within 6 months for optimal accuracy.

2. Can this standard be used for ICP-OES or ICP-MS analysis?

While primarily designed for ion chromatography, the high purity of this Specpure® solution makes it compatible with ICP-OES and ICP-MS applications, provided the matrix is compatible with your instrument’s requirements.

3. Is this solution traceable to NIST or other international standards?

Yes, the standard is manufactured under ISO 17034 and ISO/IEC 17025 guidelines, with traceability to NIST or equivalent reference materials, as documented in the included certificate of analysis.

4. What precautions should be taken during storage to maintain accuracy?

Store the bottle tightly sealed in a cool, dark place (preferably below 25°C) and avoid exposure to direct sunlight or temperature fluctuations. Use amber glass packaging to prevent photodegradation.

5. Are there lower concentration alternatives available for this standard?

This product is offered at 1000µg/ml, but serial dilution can be performed using ultrapure water or appropriate solvents to achieve lower concentrations as needed for specific applications.
