Product Overview
This Specpure® calcium plasma standard solution delivers a certified 1000µg/ml concentration in a stable, aqueous matrix, ensuring unmatched accuracy for spectroscopic techniques like ICP-OES and AAS. Manufactured under stringent quality controls, it adheres to the highest purity standards, eliminating matrix interferences that compromise results. The solution is traceable to NIST reference materials, guaranteeing reliability for calibration curves, method validation, and routine elemental analysis. Its low-acid formulation minimizes instrument corrosion while maintaining long-term stability, even after repeated use. The Specpure® grade ensures freedom from alkaline, earth, and transition metal contaminants, making it ideal for trace-level determinations in complex samples. Packaged in HDPE bottles with tamper-evident seals, the solution resists UV degradation and contamination during storage. Compatibility with most plasma-based instruments is verified, with no requirement for additional dilution in standard operating protocols. For labs demanding consistent, high-precision calcium quantification, this standard eliminates variability associated with lower-grade alternatives.
FAQs
1. What is the shelf life of this calcium plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used directly for ICP-MS analysis?
While optimized for ICP-OES/AAS, it can be used for ICP-MS after appropriate dilution to match the instrument’s linear range and avoid matrix suppression effects.
3. Is this solution compatible with organic solvents?
No, this is an aqueous standard. For organic-based applications, a separate organometallic standard or solvent-compatible calcium source is recommended.
4. How is the 1000µg/ml concentration verified?
The concentration is certified via gravimetric preparation using high-purity calcium carbonate, followed by multi-point validation against NIST-traceable reference materials.
5. What precautions should be taken during handling?
Wear nitrile gloves and safety goggles to prevent skin/eye contact. Avoid pipetting by mouth, and work in a fume hood if handling large volumes to minimize inhalation risk.
