Product Overview
This Specpure® silver plasma standard solution delivers unmatched precision for trace metal quantification, formulated with 10µg/ml silver (Ag) in a stabilized aqueous matrix. Engineered for compatibility with ICP-OES, AAS, and ICP-MS systems, the solution eliminates matrix interference risks while ensuring long-term stability. The Specpure® grade guarantees ultra-low impurity levels (<10 ppb for most contaminants), with each batch rigorously tested for accuracy against NIST-traceable references. Packaged in a 100ml HDPE bottle with a tamper-evident seal, the solution resists photodegradation and microbial contamination. Its nitric acid-based matrix (2% v/v) prevents silver precipitation while maintaining homogeneity across the entire concentration range. The included Certificate of Analysis provides lot-specific data for traceability, including density (1.01 g/cm³ at 20°C), pH (1.5–2.0), and expiry validation. Designed for seamless integration into calibration curves, this standard solution reduces preparation time by 40% compared to solid reference materials, with no sonication or heating required prior to use.
FAQs
1. What is the shelf life of this silver plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for mercury analysis alongside silver?
No, this solution is optimized exclusively for silver quantification. Mercury requires a separate standard due to its volatile nature and different matrix requirements.
3. Is the 2% nitric acid matrix compatible with all ICP-MS instruments?
Yes, the 2% v/v nitric acid concentration is universally compatible with standard ICP-MS sample introduction systems, including nebulizers and spray chambers.
4. How does the Specpure® grade differ from analytical reagent grade?
Specpure® standards undergo additional purification steps to achieve impurity levels below 10 ppb for most elements, whereas AR grade typically allows up to 100 ppb contaminants.
5. What’s the recommended dilution protocol for creating lower concentration standards?
Use Class A volumetric glassware and 2% nitric acid as the diluent. For 1µg/ml, dilute 1:10; for 0.1µg/ml, perform a two-step 1:100 dilution to minimize errors.
