Product Overview
This Specpure® Praseodymium plasma standard solution delivers exceptional purity and consistency for demanding spectroscopic applications. Formulated at 1000µg/ml concentration in a stabilized aqueous matrix, it ensures minimal background interference and superior signal stability in plasma-based analytical techniques. The ultra-low impurity profile (trace metals <10 ppb) makes it ideal for calibration curves, method validation, and quality control in environmental, geological, and materials science testing. The solution comes in tamper-evident HDPE bottles with leak-proof caps to prevent contamination during storage and handling. Each batch undergoes rigorous multi-element analysis via ICP-MS to guarantee certified accuracy within ±0.5% relative standard deviation. The extended shelf life of 24 months when stored at 15-25°C eliminates frequent recalibration needs. Compatible with most autosamplers and nebulizer systems, this standard requires no additional dilution for routine analysis of praseodymium in complex matrices like alloys, ores, or biological samples. The Specpure® certification ensures compliance with ISO 17034 and NIST-traceable reference materials, providing documented traceability for GLP/GMP environments.
FAQs
1. What is the matrix composition of this Praseodymium standard solution?
The solution uses a 2% v/v nitric acid matrix with 18.2 MΩ/cm ultrapure water, optimized for plasma stability and minimal spectral interferences.
2. Can this standard be used for ICP-MS analysis?
While primarily designed for ICP-OES, the solution’s purity level (trace metals <10 ppb) makes it suitable for ICP-MS when properly diluted to match instrument sensitivity requirements.
3. What alternatives exist for lower concentration requirements?
Serial dilution using the same matrix (2% HNO₃) can create working standards down to 1 ppb, or pre-diluted Specpure® standards at 100µg/ml are available separately.
4. How should unused solution be stored between uses?
Store tightly sealed at 15-25°C away from direct light. For extended storage beyond 6 months, purge headspace with argon to prevent oxidation.
5. Is this standard compatible with organic solvent-based sample preparation?
The aqueous matrix limits direct compatibility with organic solvents. For such applications, consider our Specpure® organometallic standards or perform phase transfer using ion-pairing agents.
