Product Overview
This Cadmium 10 ppm ICP-ML single-element standard delivers exceptional purity and stability for demanding analytical applications. Formulated in a high-purity acid matrix, it ensures minimal interference and maximum instrument compatibility. The standard is traceable to NIST reference materials, guaranteeing accuracy in quantitative analysis. Its 10 ppm concentration provides optimal sensitivity for ICP-MS and ICP-OES systems while maintaining linear response across calibration curves. The liquid form allows for easy dilution and handling, with a shelf life of 24 months when stored properly. Each batch undergoes rigorous quality control testing to verify concentration and eliminate contaminants. The standard comes in a leak-proof HDPE bottle with tamper-evident seal, preventing contamination during storage and transport. Its low background levels make it particularly suitable for environmental and trace metal analysis where detection limits are critical. The solution’s homogeneity ensures consistent performance across multiple aliquots, reducing variability in analytical results.
FAQs
1. What is the matrix composition of this Cadmium standard?
The standard is prepared in a dilute nitric acid matrix (2-5% v/v) to ensure stability and compatibility with most ICP systems. The exact acid concentration is optimized to prevent precipitation while maintaining low background interference.
2. Can this standard be used for AAS calibration?
While primarily designed for ICP applications, this standard can be used for AAS calibration provided the matrix is compatible with your instrument’s requirements. However, you may need to verify the acid concentration matches your AAS method specifications.
3. What is the recommended storage temperature?
Store the unopened standard at 15-25°C in its original container. Once opened, keep tightly sealed and store at the same temperature range. Avoid exposure to direct sunlight or temperature fluctuations.
4. How should I dispose of unused standard solution?
Follow your institution’s hazardous waste disposal protocols for heavy metal solutions. The standard should be treated as hazardous waste due to its cadmium content and acid matrix.
5. What documentation comes with each batch?
Each bottle includes a Certificate of Analysis detailing the certified concentration, uncertainty, expiration date, and traceability information. The certificate also lists the batch number and storage recommendations.
