Product Overview

This Praseodymium 10000 ppm ICP single-element standard delivers exceptional purity and stability for high-precision instrumental analysis. Formulated in a nitric acid matrix (2-5% v/v), the solution ensures minimal interference and maximum compatibility with ICP-OES, ICP-MS, and atomic absorption spectroscopy (AAS) systems. The concentration is rigorously verified against NIST-traceable reference materials, guaranteeing ±1% accuracy for reliable calibration curves and quantitative determinations. Packaged in HDPE bottles with tamper-evident seals, the standard resists contamination and degradation, maintaining integrity during storage and handling. Its low-particle formulation prevents nebulizer clogging in ICP instruments, while the extended shelf life (24 months unopened) reduces replacement frequency. The solution’s homogeneous composition eliminates settling risks, ensuring consistent performance across repeated analyses. Designed for labs requiring high-throughput rare earth element testing, this standard meets ISO 17034 and ISO Guide 31 requirements for reference materials, with batch-specific certificates of analysis provided for full traceability.

FAQs

1. What is the matrix composition of this Praseodymium standard?

The standard is prepared in a 2-5% v/v nitric acid matrix, which is optimized for ICP instrumentation and ensures complete dissolution of the Praseodymium without residual particulates. The acidic medium also prevents hydrolysis and precipitation over time.

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

For most ICP-MS applications, this 10000 ppm concentration will require dilution to avoid detector saturation. Typical working ranges for ICP-MS are in the ppb to low ppm levels, so a 1:1000 or 1:10,000 dilution is commonly applied depending on the instrument’s linear range.

3. How does the packaging prevent contamination during storage?

The standard is supplied in HDPE bottles with polypropylene caps and tamper-evident seals. HDPE is chosen for its chemical resistance to nitric acid and low leachable content, while the seal ensures no environmental contaminants enter the solution during storage or transport.

4. What alternatives exist for lower concentration Praseodymium standards?

For applications requiring lower concentrations, serial dilution of this 10000 ppm standard using ultra-pure nitric acid (or a matching matrix) is recommended. Alternatively, pre-diluted Praseodymium standards at 1000 ppm or 100 ppm are available for direct use in sensitive analyses.

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

Store the unopened standard at 15–25°C in its original packaging, away from direct sunlight and sources of heat. Once opened, tighten the cap immediately after use and avoid prolonged exposure to air to minimize oxidation or evaporation of the matrix.
