Product Overview
This Bismuth single-element standard (1000 ppm) is formulated for high-precision ICP-Mass Spectrometry applications, ensuring reliable calibration and trace-level detection. The solution is prepared from ultra-high-purity bismuth metal dissolved in a stabilized matrix, minimizing interference and maximizing instrument sensitivity. The 100 ml pack size provides sufficient volume for repeated calibrations without compromising stability. Each batch undergoes rigorous testing for homogeneity, concentration accuracy (±1% tolerance), and long-term stability (minimum 12 months when stored properly). The aqueous formulation eliminates particulate contamination risks while maintaining compatibility with most ICP-MS systems. Traceability to NIST reference materials ensures compliance with ISO 17025 standards, making it suitable for research-grade applications where data integrity is critical. The solution’s low acidity (≤2% HNO₃) prevents instrument corrosion while preserving elemental stability. Ideal for laboratories requiring consistent performance in multi-element analysis protocols.
FAQs
1. What matrix is used in this Bismuth standard solution?
This standard uses a dilute nitric acid matrix (≤2% HNO₃) to ensure complete dissolution and long-term stability of the bismuth ions without introducing significant spectral interferences.
2. Can this standard be used for ICP-OES applications?
While optimized for ICP-MS, the 1000 ppm concentration is suitable for ICP-OES after appropriate dilution, though matrix effects should be evaluated for your specific instrument configuration.
3. What is the shelf life of this unopened standard?
The solution maintains its certified concentration for at least 12 months from the date of manufacture when stored unopened at 15-25°C, protected from light exposure.
4. Are there any known elemental interferences with this Bismuth standard?
Bismuth has minimal common interferences, but potential overlaps with lead isotopes (²⁰⁸Pb with ²⁰⁹Bi) should be monitored in complex matrices using collision/reaction cell technology.
5. What documentation is provided with each batch?
Each unit includes a certificate of analysis detailing concentration, uncertainty, traceability, expiration date, and recommended storage conditions, along with batch-specific spectral purity data.
