Product Overview
This Specpure® Holmium plasma standard solution delivers a certified 10µg/ml concentration in a high-purity aqueous matrix, engineered for exceptional accuracy in inductively coupled plasma (ICP) and atomic absorption spectroscopy (AAS) applications. The solution undergoes rigorous multi-stage purification to eliminate trace contaminants, ensuring minimal interference and maximum reproducibility in elemental quantification. Its stability is guaranteed through advanced chelation and pH buffering, preventing precipitation or degradation over extended storage periods. The Specpure® grade adheres to international reference material standards, providing full traceability to NIST/SRM equivalents for compliance with ISO 17025 and GLP protocols. Packaged in HDPE bottles with tamper-evident seals, the solution resists leaching and external contamination, while the 100ml volume offers optimal balance between cost-efficiency and repeated use. Each batch includes a comprehensive Certificate of Analysis (CoA) detailing elemental impurities, density, and expiration validation. Compatible with most autosamplers and nebulizers, this standard eliminates the need for in-house dilution in routine calibration curves, reducing procedural errors and labor costs.
FAQs
1. What is the shelf life of this Holmium 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.
2. Can this standard be used for ICP-MS analysis?
Yes, the 10µg/ml concentration is suitable for ICP-MS after appropriate dilution. The ultra-low impurity profile minimizes spectral overlaps in mass spectrometry.
3. What diluent is used in this solution?
The matrix consists of 2% v/v high-purity nitric acid (HNO₃) in deionized water (18.2 MΩ·cm), ensuring compatibility with plasma-based techniques.
4. Is this solution compatible with organic solvents?
No, the aqueous formulation is designed for water-based systems. For organic-soluble standards, consider alternative Holmium organometallic compounds.
5. How does the Specpure® grade differ from analytical reagent grade?
Specpure® undergoes additional purification steps to reduce metallic and anionic impurities below 10 ppb, critical for sub-ppb detection limits in high-sensitivity applications.
