Product Overview

This Specpure® zinc plasma standard solution delivers a certified 10µg/ml concentration in a stable aqueous matrix, engineered for high-precision atomic spectroscopy applications. The ultra-high purity grade eliminates matrix interferences, ensuring accurate calibration curves and minimal background noise in ICP-OES and AAS systems. Each batch undergoes rigorous multi-element analysis to guarantee consistency, with traceability to NIST SRM standards for absolute reliability. The solution’s low acidity (typically <2% HNO₃) prevents instrument corrosion while maintaining long-term stability—critical for laboratories requiring reproducible results over extended periods. Packaged in HDPE bottles with tamper-evident seals, the solution resists contamination and evaporation, preserving integrity during storage and handling. The 100ml pack size balances cost-efficiency with sufficient volume for routine calibration, quality control, and method validation without excessive waste. Compatible with most autodilution systems, it integrates seamlessly into automated workflows, reducing manual preparation errors. The Specpure® certification ensures compliance with ISO 17025 and GLP standards, making it the preferred choice for research labs, testing facilities, and academic institutions demanding uncompromised analytical performance.

FAQs

1. What is the shelf life of this zinc 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 for graphite furnace AAS?

Yes, the 10µg/ml concentration is suitable for graphite furnace AAS, but dilution may be required depending on your instrument’s linear range and sample matrix.

3. Is this solution compatible with organic solvents?

The aqueous nitric acid matrix is not miscible with organic solvents. For organic-based applications, consider a zinc standard in an alternative solvent like methanol or toluene.

4. How is the concentration verified?

Each batch is quantified using primary standard reference materials and validated via ICP-OES cross-checking to ensure ±1% accuracy of the stated 10µg/ml concentration.

5. What alternatives exist for higher concentration needs?

For concentrations above 10µg/ml, explore Specpure® zinc standards at 100µg/ml or 1000µg/ml, which can be diluted to your required working range.
