Product Overview
This Holmium plasma standard solution delivers exceptional purity at 10,000µg/ml concentration, formulated to Specpure® standards for atomic spectroscopy applications. The aqueous matrix ensures complete solubility and stability, eliminating particulate interference during analysis. Each batch undergoes rigorous multi-element impurity testing to guarantee <10ppb residual contamination levels, with certified values traceable to NIST reference materials. The solution’s acidified base (typically 2% HNO₃) prevents hydrolysis and maintains elemental integrity over extended storage periods. Packaged in HDPE bottles with tamper-evident seals, the solution resists container leaching while preserving concentration accuracy. The high 10,000µg/ml concentration allows for precise serial dilutions, reducing preparation errors in calibration curves. Unlike generic standards, this Specpure® grade undergoes additional purification steps to remove spectroscopic interferences from rare earth element overlaps. The solution’s homogeneity is verified through 10-point sampling analysis, ensuring consistent performance across the entire volume. Compatible with all major ICP-OES and ICP-MS systems, the solution’s matrix matches common sample preparation protocols for seamless integration into existing workflows. The extended shelf life of 24 months from manufacture date minimizes replacement frequency while maintaining analytical reliability.
FAQs
1. What is the matrix composition of this Holmium standard solution?
The solution uses a 2% nitric acid matrix, which provides optimal stability for Holmium while preventing hydrolysis and precipitation over time.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the ultra-low impurity profile and high purity make it suitable for both techniques, though you may need to adjust dilution factors based on your instrument’s sensitivity requirements.
3. What is the difference between this Specpure® grade and standard reagent grades?
Specpure® undergoes additional purification steps specifically to remove spectroscopic interferences from other rare earth elements, resulting in cleaner spectra and more accurate quantification.
4. How should I store this solution after opening?
Store tightly sealed at room temperature (15-25°C) away from direct sunlight. The acidified matrix provides inherent stability, but minimizing air exposure prevents potential contamination.
5. What documentation comes with this standard?
Each bottle includes a certificate of analysis with batch-specific data including concentration values, uncertainty statements, and impurity profiles traceable to NIST standards.
