Product Overview
This Specpure® Hafnium AAS standard solution delivers 1000µg/ml concentration in a stabilized nitric acid matrix, engineered for uncompromising accuracy in trace metal analysis. The ultra-high-purity grade ensures minimal matrix interferences, with impurities controlled below detection limits for most AAS and ICP-OES applications. Each batch undergoes rigorous multi-element analysis with certification traceable to NIST standards, guaranteeing consistency across research and industrial workflows. The solution’s long-term stability (minimum 24 months when stored properly) eliminates frequent recalibration needs, while the acidified formulation prevents precipitation or adsorption losses. Packaged in HDPE bottles with tamper-evident seals, it resists contamination during storage and handling. The 100ml and 500ml pack sizes cater to both routine laboratory use and high-throughput environments, with the larger volume offering cost efficiency for frequent users. Compatible with most autosamplers and dilution systems, this standard integrates seamlessly into existing AAS methodologies without requiring protocol adjustments.
FAQs
1. What is the matrix composition of this Hafnium AAS standard?
The solution uses a 2-5% nitric acid matrix, optimized to maintain Hafnium solubility while minimizing spectral interferences in AAS analysis. The exact acid concentration is specified on the certificate of analysis for each batch.
2. Can this standard be used for ICP-MS applications?
While primarily designed for AAS, the high purity makes it suitable for ICP-MS with proper dilution. However, verify compatibility with your ICP-MS instrument’s introduction system, as the nitric acid concentration may require adjustment for plasma stability.
3. How does the Specpure® grade differ from standard AAS grades?
Specpure® undergoes additional purification steps to reduce trace contaminants (e.g., Zr, Ti, Nb) that often co-exist with Hafnium in natural sources. This results in lower detection limits and reduced background correction requirements during analysis.
4. What’s the recommended storage temperature for long-term stability?
Store between 15-25°C in the original tightly sealed bottle, away from direct sunlight. Avoid refrigeration, as temperature fluctuations can compromise the seal integrity and introduce condensation-related contamination.
5. Are custom concentrations or larger pack sizes available?
Custom dilutions (e.g., 100µg/ml, 10µg/ml) can be prepared upon request with adjusted certification. For bulk requirements beyond 500ml, contact our technical team for volume pricing and lead times.
