Product Overview

This Specpure® Zirconium plasma standard solution delivers 1000µg/ml Zr in a 2% nitric acid matrix, engineered for exceptional accuracy in atomic spectroscopy applications. The ultra-high purity grade (99.999% metals basis) ensures minimal background interference, making it ideal for low-level zirconium detection in complex matrices. Each batch undergoes rigorous quality control with NIST-traceable certification, guaranteeing consistent performance across ICP-OES, ICP-MS, and AAS instrumentation. The solution’s stable formulation in high-purity nitric acid prevents precipitation while maintaining long-term concentration integrity. Packaged in HDPE bottles with tamper-evident seals, it meets ISO 17034 reference material standards. The 2% HNO₃ matrix is optimized for compatibility with most plasma spectroscopy systems without requiring additional dilution for routine analysis. This standard eliminates matrix effects common in lower-grade alternatives, reducing calibration errors in environmental, geological, and materials science applications where zirconium quantification is critical.

FAQs

1. What is the shelf life of this zirconium 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. The 2% HNO₃ matrix helps maintain stability, but we recommend recalibrating if stored beyond these periods.

2. Can this standard be used directly for ICP-MS analysis without dilution?

While the 1000µg/ml concentration is suitable for many ICP-OES applications, ICP-MS typically requires dilution to ppb levels. We recommend preparing working standards by serial dilution with 2% HNO₃ to match your instrument’s linear range and avoid detector saturation.

3. What material are the bottles made from, and are they compatible with HF?

The bottles are made from high-density polyethylene (HDPE), which is resistant to 2% HNO₃ but not compatible with hydrofluoric acid. For applications requiring HF, transfer the solution to PTFE containers immediately upon opening to prevent container degradation.

4. How does the Specpure® grade compare to standard analytical grades?

Specpure® grade offers significantly lower impurity levels (typically <10 ppb for most metallic contaminants) compared to standard analytical grades that may contain 100-1000 ppb impurities. This reduces background noise in trace analysis and improves detection limits for zirconium in complex samples.

5. What certification documentation is provided with this standard?

Each bottle includes a certificate of analysis with batch-specific data including the exact zirconium concentration, expiry date, and impurity profile. The certification is traceable to NIST SRM 3169 (Zirconium Standard) and includes uncertainty statements compliant with ISO Guide 34 requirements.
