Product Overview
The Specpure® cesium plasma standard solution delivers 10,000µg/ml Cs in a 2% nitric acid matrix, engineered for uncompromised accuracy in atomic spectroscopy applications. This ultra-high-purity solution undergoes rigorous multi-stage purification to eliminate trace metal contaminants (typically <10 ppb), ensuring minimal spectral interference during analysis. The cesium concentration is certified via gravimetric preparation with NIST-traceable reference materials, providing metrological reliability for calibration curves in ICP-OES, ICP-MS, and flame/furnace AAS systems. The solution’s low-viscosity aqueous formulation guarantees consistent nebulization in plasma instruments, while the nitric acid matrix prevents precipitation and maintains long-term stability. Packaged in HDPE bottles with tamper-evident seals, the solution resists leaching and contamination during storage. Each batch includes a comprehensive Certificate of Analysis detailing elemental impurities, density, and pH values. The high cesium concentration allows for flexible dilution to working standards (1–1000 µg/ml) without sacrificing precision, making it cost-effective for high-throughput laboratories. Compatible with most autosampler systems, this standard eliminates the need for in-house preparation of cesium solutions, reducing procedural errors and labor costs.
FAQs
1. What is the shelf life of this cesium plasma standard solution when unopened?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C in its original packaging. Avoid exposure to direct sunlight or temperature fluctuations.
2. Can this standard be used for both ICP-OES and ICP-MS without dilution?
The 10,000µg/ml concentration is designed for dilution to working ranges. For ICP-OES, typical working standards are 1–100 µg/ml; for ICP-MS, 0.1–10 µg/ml. Direct use may exceed linear dynamic ranges or damage instrument components.
3. What materials are the bottles and caps made of, and are they resistant to nitric acid?
The bottles are HDPE (high-density polyethylene) with PP (polypropylene) caps, both chemically inert to 2% HNO₃. The materials meet USP Class VI standards for leachables and are tested for metal ion release.
4. How does the Specpure® grade differ from standard analytical-grade cesium solutions?
Specpure® undergoes additional purification steps (sub-boiling distillation, ion exchange) to reduce trace metal impurities to <10 ppb, compared to 100–1000 ppb in analytical grade. This minimizes spectral overlaps in multi-element analysis.
5. Is this solution compatible with organic solvents for specialized applications?
The aqueous nitric acid matrix is immiscible with most organic solvents. For organic-based standards, consider cesium salts (e.g., CsCl) dissolved in methanol or acetone, but recalibration will be required due to viscosity and ionization differences.
