Product Overview
This Chromium plasma standard solution from Specpure® delivers exceptional purity and consistency for demanding analytical applications. Formulated at a concentration of 1000µg/ml in a stabilized aqueous matrix, it ensures minimal background interference and superior signal stability during atomic spectroscopy techniques. The Specpure® grade guarantees ultra-low contamination levels, making it ideal for trace metal analysis where precision is critical. Each batch undergoes rigorous quality control to maintain lot-to-lot reproducibility, with certification of analysis provided for full traceability. The solution is compatible with most modern spectrometers and requires no additional preparation for direct calibration use. Its long-term stability (when stored properly) reduces the need for frequent recalibration, while the nitric acid-based matrix prevents precipitation and maintains homogeneity. Whether used as a primary standard or for routine instrument verification, this Chromium solution meets the exacting requirements of environmental testing, metallurgical analysis, and clinical research laboratories.
FAQs
1. What is the shelf life of this Chromium plasma standard solution when unopened?
The unopened solution maintains its certified concentration for 24 months from the date of manufacture when stored at room temperature (15-25°C) in its original container. Always check the expiration date on the label.
2. Can this solution be used directly for ICP-MS analysis without further dilution?
While the 1000µg/ml concentration is suitable for many applications, ICP-MS typically requires lower concentrations (ppb range). We recommend serial dilution with ultra-pure water and matrix-matched standards for optimal ICP-MS performance.
3. What material is the container made of, and is it compatible with long-term storage?
The solution is supplied in high-density polyethylene (HDPE) bottles with polypropylene caps, both of which are chemically resistant to the nitric acid matrix and prevent leaching of contaminants during storage.
4. How does the Specpure® grade differ from standard analytical grades?
Specpure® standards undergo additional purification steps to remove trace impurities that could interfere with ultra-trace analysis. The grade is specifically designed for techniques requiring detection limits in the ppt-ppb range, with certified impurity levels typically below 10 ppb.
5. What safety precautions should be taken when handling this solution?
Always wear nitrile gloves, safety goggles, and a lab coat when handling. Work in a fume hood due to the nitric acid content. In case of skin contact, rinse immediately with plenty of water and seek medical advice if irritation persists.
