Product Overview
This Rhenium AAS standard solution from Specpure® delivers exceptional purity (1000µg/ml concentration) for demanding analytical applications where trace-level accuracy is critical. Formulated in a stabilized aqueous matrix, it ensures long-term stability and minimal matrix interference during atomic absorption spectroscopy (AAS) or inductively coupled plasma (ICP) analysis. The Specpure® grade guarantees ≤10 ppb maximum impurity levels for all non-target elements, eliminating background noise that could skew results in ultra-trace detection. Each batch undergoes rigorous multi-element ICP-MS validation to confirm certified concentrations, with lot-specific certificates of analysis provided for full traceability. The solution’s homogeneous composition prevents precipitation or phase separation, even during prolonged storage, while the acidified base (typically 2-5% HNO₃) maintains elemental solubility without introducing contaminants. Compatible with most AAS and ICP-OES instruments, this standard eliminates the need for in-house dilution preparation, reducing procedural errors and saving lab time. The amber glass packaging with PTFE-lined caps prevents photodegradation and leaching, preserving integrity until the last drop.
FAQs
1. What is the shelf life of this Rhenium AAS 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, protected from light.
2. Can this standard be used directly for ICP-OES without further dilution?
While the 1000µg/ml concentration is suitable for many AAS applications, ICP-OES typically requires dilution to 1–100 µg/ml ranges to avoid detector saturation; always verify instrument-specific linear ranges.
3. How does the Specpure® grade differ from standard reagent-grade rhenium solutions?
Specpure® standards undergo additional purification steps to reduce impurities to ≤10 ppb (vs. 100–1000 ppb in reagent grade), with certified multi-element analysis to ensure no spectral overlaps in AAS/ICP.
4. Is this solution compatible with autodilution systems for high-throughput labs?
Yes, the homogeneous, particle-free formulation is optimized for automated diluters and robotic sampling systems, though we recommend priming lines with 2% HNO₃ between samples to prevent carryover.
5. What documentation is provided for quality assurance?
Each bottle includes a lot-specific Certificate of Analysis (CoA) detailing certified concentration, impurity profile, expiration date, and storage conditions, along with traceability to NIST SRMs where applicable.
