Product Overview
This cadmium plasma standard solution delivers exceptional purity and accuracy for demanding analytical applications. Formulated at a concentration of 10,000µg/ml in a stabilized nitric acid matrix, it meets the rigorous requirements of Specpure® grade standards. The solution is manufactured under strict quality control protocols to ensure lot-to-lot consistency and traceability to NIST reference materials. Its low impurity profile minimizes interference in spectroscopic analysis, making it particularly suitable for environmental testing, metallurgical analysis, and clinical toxicology research. The solution comes in high-density polyethylene (HDPE) bottles with tamper-evident seals to prevent contamination during storage and handling. Each batch undergoes comprehensive certification testing, with detailed certificates of analysis provided for quality assurance. The nitric acid base ensures complete dissolution of cadmium ions, eliminating precipitation risks that could compromise analytical results. This standard is compatible with most modern atomic absorption spectrometers and inductively coupled plasma instruments without requiring additional preparation steps.
FAQs
1. What is the shelf life of this cadmium plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature (15-25°C). Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for ICP-MS analysis?
Yes, this 10,000µg/ml cadmium standard is suitable for ICP-MS applications when properly diluted. The ultra-low impurity profile ensures minimal spectral interference during mass spectrometry analysis.
3. What dilution factors are recommended for AAS calibration?
For typical flame AAS applications, we recommend serial dilutions to achieve working standards in the 0.1-5.0µg/ml range. Graphite furnace AAS may require further dilution to 0.01-0.5µg/ml concentrations.
4. Is this solution compatible with autoclave sterilization?
No, this standard solution should not be autoclaved as heat exposure may alter the cadmium concentration and potentially degrade the HDPE container material.
5. What documentation is provided with each bottle?
Every bottle includes a comprehensive certificate of analysis detailing the exact cadmium concentration, trace impurities, expiration date, and lot-specific quality control data.
