Product Overview
This Specpure® refractory metals plasma standard solution is engineered for high-precision elemental analysis in advanced spectroscopic techniques. Formulated with 13 critical refractory metals—aluminum (Al), boron (B), chromium (Cr), hafnium (Hf), molybdenum (Mo), niobium (Nb), silicon (Si), tantalum (Ta), titanium (Ti), vanadium (V), tungsten (W), and zirconium (Zr)—each stabilized at a 100µg/ml concentration in a nitric acid matrix, this solution ensures minimal interference and maximum accuracy. The Specpure® grade guarantees ultra-low impurity levels, making it indispensable for calibration curves, method validation, and trace-level quantitation in ICP-OES, ICP-MS, and atomic absorption spectroscopy (AAS). The aqueous formulation eliminates particulate contamination risks while maintaining long-term stability under standard lab storage conditions. Compatible with most autosamplers and nebulizers, this solution reduces preparation time and eliminates the need for multi-element stock dilutions. Its broad elemental coverage supports applications in metallurgy, materials science, environmental testing, and geological research where refractory metal analysis is critical. The 500ml and 100ml pack sizes offer flexibility for high-throughput labs and specialized research projects alike.
FAQs
1. What is the shelf life of this refractory metals plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C in its original container. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used directly for ICP-MS analysis without further dilution?
The 100µg/ml concentration is typically too high for direct ICP-MS analysis and requires dilution to avoid detector saturation. A 1:100 or 1:1000 dilution is commonly used depending on the instrument sensitivity and target analyte range.
3. Is this solution compatible with organic solvents for specific applications?
This aqueous standard is not designed for organic solvent compatibility. For organic-based analyses, consider a separate organometallic standard or consult the manufacturer for custom formulations.
4. How does the Specpure® grade differ from standard analytical grades?
Specpure® standards undergo additional purification steps to remove trace contaminants, particularly for refractory metals where matrix effects are critical. This results in lower detection limits and reduced spectral interferences compared to general-purpose standards.
5. What precautions should be taken when handling this nitric acid-based solution?
Always wear nitrile gloves, safety goggles, and a lab coat when handling. Work in a fume hood to avoid inhalation of nitric acid vapors, and neutralize spills immediately with sodium bicarbonate or a dedicated spill kit.
