Product Overview
This Specpure® selenium plasma standard solution delivers unmatched precision for spectroscopic analysis, formulated at a certified 10µg/ml concentration in a stabilized nitric acid matrix. Engineered for minimal interference and maximum stability, the solution is manufactured under ISO 17034 and ISO/IEC 17025 accreditation, ensuring traceability to NIST SRMs. The ultra-low background impurity profile (<10 ppt for most metals) eliminates false positives in environmental, clinical, or industrial testing. Housed in a HDPE bottle with a tamper-evident seal, the solution resists leaching and contamination, maintaining integrity for up to 24 months when stored at 15–25°C. Its compatibility with autodiluters and automated systems streamlines workflows, while the lot-specific certificate of analysis provides transparency for audit compliance. Ideal for laboratories requiring reproducible results in selenium quantification, this standard eliminates the need for in-house preparation, reducing human error and reagent waste.
FAQs
1. What is the shelf life of this selenium 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 both ICP-OES and ICP-MS?
Yes, the Specpure® grade is optimized for compatibility with both ICP-OES and ICP-MS, offering linear response across dynamic ranges without matrix effects.
3. Is the nitric acid concentration specified in the certificate of analysis?
The certificate details the exact nitric acid concentration (typically 2–5% v/v), which is optimized to prevent selenium precipitation while ensuring instrument compatibility.
4. Are there alternatives for lower concentration selenium standards?
For applications requiring <10µg/ml, consider serial dilution using the provided stability data or explore our 1µg/ml and 0.1µg/ml Specpure® selenium standards.
5. How should I dispose of unused solution?
Follow local regulations for hazardous chemical disposal. Neutralize with a base (e.g., sodium hydroxide) before disposal if permitted, or use a licensed hazardous waste service.
