Product Overview
This 10 ppm palladium single-element standard is formulated for inductively coupled plasma-mass spectrometry (ICP-ML) applications, offering exceptional purity and consistency for critical analytical workflows. The solution is prepared in a high-purity acid matrix to prevent precipitation and ensure long-term stability, with certification traceable to NIST standards for reliable quantification. The low concentration (10 ppm) enables precise calibration curves and spike recovery tests without requiring extensive dilution, while the single-element format eliminates cross-contamination risks associated with multi-element standards. Packaged in HDPE bottles with tamper-evident seals, the standard resists leaching and external contamination, maintaining integrity during storage and transport. Each batch undergoes rigorous testing for homogeneity, with certificates of analysis provided for lot-specific accuracy verification. The acid-stabilized composition minimizes matrix effects in complex samples, making it suitable for environmental, geological, and industrial material testing where palladium quantification is required. Compatible with most ICP-MS instruments, this standard delivers reproducible results across different lab setups, reducing variability in inter-laboratory comparisons.
FAQs
1. What is the shelf life of this 10 ppm palladium ICP standard when unopened?
The unopened standard maintains its certified concentration for 24 months from the date of manufacture when stored at 15-25°C in its original packaging. Always verify the expiration date on the label before use.
2. Can this standard be used for ICP-OES applications instead of ICP-MS?
While primarily designed for ICP-MS, this 10 ppm standard can be used for ICP-OES if the concentration aligns with your detection limits. Note that ICP-OES typically requires higher concentrations (1-100 ppm range) for optimal signal response.
3. What acid matrix is used in this palladium standard?
The standard is stabilized in a 2% nitric acid (HNO₃) matrix, which is compatible with most ICP-MS systems and prevents palladium precipitation while minimizing polyatomic interferences during analysis.
4. How should I handle potential contamination when transferring the standard?
Use dedicated, acid-washed class-A volumetric pipettes or micropipettes with low-retention tips. Pre-rinse the transfer device 3 times with the standard before aliquoting to minimize adsorption losses, especially at this low concentration.
5. Is this standard compatible with automated liquid handling systems?
Yes, the solution’s viscosity and surface tension are optimized for automated systems. However, we recommend validating with your specific instrument using the standard’s lot-specific density value provided in the COA to ensure accurate dispensing.
