Product Overview
This Zinc plasma standard solution (10,000µg/ml) from Specpure® is engineered for laboratories demanding uncompromised accuracy in trace metal quantification. Formulated in a high-purity acid matrix, it eliminates interference risks while ensuring long-term stability—critical for reproducible results across ICP-OES, ICP-MS, and atomic absorption spectroscopy (AAS) workflows. The solution undergoes rigorous multi-stage purification to remove contaminants, achieving parts-per-billion (ppb) level precision. Its certified concentration traceability to NIST standards guarantees compliance with ISO 17025 and GLP protocols. The aqueous base ensures compatibility with most autosamplers and nebulizers, reducing maintenance downtime. Housed in HDPE bottles with tamper-evident seals, it prevents leaching or evaporation, preserving integrity during storage. Ideal for environmental testing, pharmaceutical QC, and materials science, this standard delivers consistent performance even in complex sample matrices. The 10,000µg/ml concentration allows flexible dilution for low-range calibrations without sacrificing linearity. Each batch includes a comprehensive Certificate of Analysis (CoA) detailing impurity profiles and expiration validation.
FAQs
1. What is the shelf life of this Zinc plasma standard solution when unopened?
The unopened solution remains stable for 24 months from the date of manufacture when stored at 15–25°C in its original packaging. Avoid exposure to direct sunlight or temperature fluctuations.
2. Can this standard be used directly for ICP-MS without further dilution?
No, the 10,000µg/ml concentration is typically too high for direct ICP-MS analysis. Dilution to the ppb or low-ppm range is required using ultra-pure acids or deionized water (18.2 MΩ·cm) to match your instrument’s linear range.
3. Is this solution compatible with organic solvents like methanol or acetone?
The aqueous matrix is optimized for water-based systems. For organic solvent compatibility, verify miscibility via a small-scale test, as precipitation or phase separation may occur with certain solvents.
4. How does the Specpure® grade differ from standard analytical grades?
Specpure® undergoes additional purification steps to reduce metallic and anionic impurities to sub-ppb levels, ensuring minimal background interference. Standard grades may contain higher residual contaminants affecting sensitivity in ultra-trace analysis.
5. What documentation is provided with each batch for quality assurance?
Every batch includes a Certificate of Analysis (CoA) with lot-specific data: exact concentration, impurity profiles (via ICP-MS), expiration date, and storage instructions. Traceability to NIST SRMs is documented for regulatory compliance.
