Product Overview

This Specpure® Zirconium plasma standard solution delivers unmatched precision for atomic spectroscopy applications, formulated at a concentration of 10,000µg/ml in a stabilized aqueous matrix. Engineered for minimal matrix interference, it ensures reliable calibration curves and trace-level detection in ICP-OES, ICP-MS, and AAS systems. The Specpure® grade guarantees ultra-low impurity levels (<10 ppb for most metallic contaminants), eliminating background noise and enhancing analytical accuracy. Each batch undergoes rigorous multi-element analysis with certified traceability to NIST standards, ensuring consistency across experiments. The solution’s long-term stability (shelf life: 24 months unopened) is achieved through proprietary stabilization techniques, preventing precipitation or concentration drift. Compatible with most autosamplers and nebulizers, it requires no additional dilution for routine calibration—though further dilution is recommended for ultra-trace analysis. Packaged in HDPE bottles with tamper-evident seals, the solution resists leaching and contamination, while the amber tint protects against photodegradation. Ideal for laboratories demanding reproducibility, this standard eliminates variability introduced by in-house preparation, reducing workflow errors and reagent waste.

FAQs

1. What is the matrix composition of this zirconium standard solution?

The solution uses a nitric acid-based matrix (2-5% v/v HNO₃) with proprietary stabilizers to prevent hydrolysis and maintain homogeneity. The exact composition is optimized for plasma compatibility and minimal spectral interference.

2. Can this standard be used for direct aspiration in ICP-MS without dilution?

While the 10,000µg/ml concentration is suitable for ICP-OES, direct aspiration in ICP-MS may exceed the linear range for most instruments. A 1:100 or 1:1000 dilution is typically recommended for ICP-MS to avoid detector saturation and ensure accurate low-ppb quantification.

3. How does the Specpure® grade differ from standard analytical grades?

Specpure® standards undergo additional purification steps, including sub-boiling distillation and ion-exchange chromatography, to reduce trace impurities to <10 ppb for most elements. Standard analytical grades often contain impurities at 100-1000 ppb levels, which can introduce systematic errors in high-sensitivity applications.

4. What is the recommended storage temperature for long-term stability?

Store the unopened solution at 15–25°C in its original container, away from direct sunlight and heat sources. Once opened, tighten the cap immediately after use and store at 4°C to minimize evaporation and contamination. Avoid freezing, as it may alter the matrix composition.

5. Are the bottles certified for trace metal analysis?

The HDPE bottles are pre-cleaned with ultra-pure acids and tested for leachable metals (<1 ppb for Zr, Hf, and other critical elements). Each bottle undergoes a rinse protocol with 18.2 MΩ·cm water prior to filling to ensure no residual contaminants affect the standard’s integrity.
