Product Overview
This Specpure® Barium plasma standard solution delivers exceptional purity and consistency for demanding analytical applications. Formulated at a precise 10µg/ml concentration in a dilute nitric acid matrix, it ensures minimal background interference and long-term stability, critical for reliable calibration curves in plasma spectrometry. The Specpure® grade guarantees traceability to NIST standards, with impurity levels rigorously controlled to sub-ppm thresholds—ideal for high-sensitivity instrumentation where matrix effects must be minimized. The solution is packaged in a 100ml HDPE bottle with a tamper-evident seal to prevent contamination during storage or handling. Its low-acidity formulation (pH ~1-2) maintains elemental solubility while reducing corrosive risks to labware. Compatible with most autodilution systems, this standard eliminates the need for in-house preparation, saving time and reducing human error in quantitative analysis. The extended shelf life (24 months unopened) further enhances cost-efficiency for laboratories requiring frequent recalibration.
FAQs
1. What is the matrix composition of this Barium standard solution?
The solution uses a dilute nitric acid matrix (typically 2-5% v/v HNO₃) to ensure complete dissolution of Barium and prevent precipitation over time.
2. Can this standard be used for ICP-MS analysis?
While optimized for ICP-OES/AAS, it can be used for ICP-MS after appropriate dilution to avoid detector saturation from the 10µg/ml concentration.
3. How should this solution be stored to maintain stability?
Store upright at 15-25°C in the original bottle, away from direct sunlight and alkaline vapors. Avoid freezing as it may alter the matrix integrity.
4. What materials are compatible with this standard for sample preparation?
Use PP, HDPE, or PFA labware. Avoid glass for long-term storage due to potential leaching of silicates that could interfere with analysis.
5. Is a certificate of analysis provided with this product?
Yes, each batch includes a COA detailing the exact concentration, traceability data, and impurity profile verified via independent third-party testing.
