Product Overview
This Vanadium plasma standard solution (10,000µg/ml) from Specpure® delivers exceptional purity and stability for demanding analytical applications. Formulated in high-grade nitric acid, it ensures minimal matrix interference and long-term consistency, making it ideal for plasma spectrometry techniques like ICP-OES and AAS. The Specpure® certification guarantees traceable accuracy with lot-specific certificates, eliminating variability in calibration curves. Each batch undergoes rigorous testing for heavy metal contaminants and particulate matter, adhering to international reference material standards. The solution’s homogeneous composition prevents sedimentation, ensuring reliable aliquoting even at microliter volumes. Compatible with most autosamplers, it reduces system carryover while maintaining signal integrity across dilution ranges. The amber glass packaging with PTFE-lined caps preserves integrity by minimizing light exposure and leaching. For labs requiring NIST-traceable vanadium standards, this solution provides a cost-effective alternative without compromising on metrological reliability. Store at 15–25°C away from direct sunlight to maintain specification compliance throughout the shelf life.
FAQs
1. What is the matrix composition of this vanadium standard solution?
The solution is prepared in 2–5% high-purity nitric acid (HNO₃) as the matrix, ensuring complete vanadium solubility and compatibility with plasma instruments. The exact acid concentration is optimized to balance stability and instrument performance.
2. Can this standard be used for graphite furnace AAS applications?
While primarily designed for plasma techniques, the solution’s ultra-low particulate content makes it suitable for graphite furnace AAS when properly diluted. However, we recommend verifying compatibility with your specific instrument’s matrix modifiers and background correction system.
3. How does the Specpure® grade differ from standard analytical grades?
Specpure® standards undergo additional purification steps to remove trace impurities (e.g., <10 ppb for most metallic contaminants) and are certified with tighter tolerances (±0.5% relative uncertainty). This reduces systematic errors in high-precision calibration compared to general analytical-grade solutions.
4. What dilution stability can be expected for working standards?
When diluted with 1% HNO₃, working standards remain stable for up to 3 months at 4°C. For long-term storage of diluted standards, we recommend adding 0.5% HCl as a stabilizer and recertifying every 6 months via spike recovery tests.
5. Are the bottles pre-cleaned for trace metal analysis?
All packaging undergoes a Class 100 cleanroom washing protocol with trace-metal-grade acids, followed by triple rinsing with 18.2 MΩ·cm water. The PTFE-lined caps are tested for vanadium leaching (<0.1 ppb/72h) to ensure no contamination during storage.
