Product Overview
This Specpure® Hafnium plasma standard solution delivers unmatched precision for atomic spectroscopy applications, formulated at a 10,000µg/ml concentration to meet rigorous analytical demands. The solution is prepared using ultra-high-purity hafnium metal dissolved in a stabilized nitric acid matrix, ensuring long-term stability and minimal matrix interference. Each batch undergoes stringent quality control, including ICP-OES verification, to guarantee accuracy within ±0.5% of the certified value. The Specpure® grade eliminates trace contaminants like zirconium, titanium, and rare earth elements, which are critical for low-detection-limit analyses in advanced research and industrial labs. Packaged in HDPE bottles with tamper-evident seals, the solution resists leaching and external contamination, preserving integrity during storage and handling. Compatible with most plasma spectroscopy instruments, it requires no additional dilution for standard calibration curves, reducing preparation time and human error. The solution’s homogeneous composition ensures consistent signal response across repeated measurements, while its extended shelf life of 24 months under proper storage conditions minimizes replacement frequency. For labs prioritizing reproducibility, this standard solution provides a reliable baseline for hafnium quantification in complex matrices, from geological samples to high-tech alloys.
FAQs
1. What is the matrix composition of this hafnium standard solution?
The solution is stabilized in a 2-5% nitric acid matrix, which ensures complete dissolution of hafnium and prevents precipitation or adsorption losses over time.
2. Can this standard be used directly for ICP-MS without further dilution?
While the 10,000µg/ml concentration is suitable for ICP-OES, ICP-MS typically requires dilution to 1-100µg/ml ranges to avoid detector saturation and matrix effects.
3. How does the Specpure® grade differ from standard analytical grades?
Specpure® standards undergo additional purification steps to remove metallic and anionic impurities below 10 ppb, making them ideal for ultra-trace analysis where background interference is critical.
4. What is the recommended storage temperature for long-term stability?
Store the unopened bottle at 15-25°C in a dark, dry place. Avoid refrigeration, as temperature fluctuations can compromise the seal integrity and introduce condensation.
5. Are the bottles provided with lot-specific certificates of analysis?
Yes, each bottle includes a COA detailing the certified hafnium concentration, expiry date, traceability to NIST standards, and batch-specific impurity profiles.
