Product Overview
This Specpure® Neodymium plasma standard solution delivers exceptional purity and stability for demanding analytical applications. Formulated at a precise 1000µg/ml concentration in a nitric acid matrix, it ensures minimal background interference and superior signal response in plasma-based techniques. The solution undergoes rigorous multi-stage purification to eliminate metallic and anionic contaminants, meeting the exacting requirements of modern spectroscopy labs. Its NIST-traceable certification guarantees measurement accuracy across calibration curves, while the acid-stabilized formulation prevents precipitation or concentration shifts during storage. The solution’s low particulate content and consistent homogeneity make it ideal for creating working standards or validating instrument performance. Packaged in HDPE bottles with tamper-evident seals, it maintains integrity during transport and long-term storage. The 2-8°C storage recommendation preserves its certified concentration values, with a 24-month shelf life from date of manufacture when stored properly. Each batch is accompanied by a comprehensive Certificate of Analysis detailing elemental impurities and exact concentration values.
FAQs
1. What is the matrix composition of this Neodymium standard solution?
The solution is prepared in 2% v/v ultra-pure nitric acid, which serves as both the solvent and stabilizer for the Neodymium content.
2. Can this standard be used directly for ICP-MS analysis without dilution?
While the 1000µg/ml concentration is suitable for some ICP-OES applications, most ICP-MS methods require dilution to the ppb range to avoid detector saturation.
3. How does the Specpure® grade differ from standard analytical grades?
Specpure® undergoes additional purification steps to reduce trace metallic impurities below 10 ppb for most elements, with verified absence of spectral interferences.
4. What is the recommended procedure for preparing working standards from this solution?
Use Class A volumetric glassware and ultra-pure water (18.2 MΩ·cm) for serial dilutions, with thorough mixing between each step to maintain homogeneity.
5. Are there any known element interferences with Neodymium at this concentration?
Potential spectral overlaps may occur with Praseodymium (Pr) and Samarium (Sm) in some instruments, requiring mathematical correction or alternative wavelengths.
