Specifications Table
Product Name – Vanadium, 1000 ppm ICP-ML, single-element standard
Quantity/Pack Size – 100 ml
Form – Liquid (in 2% HNO₃)
Grade – ICP-MS/ICP-OES Traceable
Application – Elemental analysis, calibration, quality control
Product Overview
This 1000 ppm Vanadium single-element ICP standard is meticulously prepared in a 2% nitric acid matrix to ensure long-term stability and compatibility with ICP-MS and ICP-OES instrumentation. The solution undergoes rigorous quality control, including multi-point calibration verification against NIST-traceable reference materials, to guarantee ±2% concentration accuracy. Packaged in HDPE bottles with tamper-evident seals, it minimizes contamination risks while maintaining elemental integrity during storage. The ultra-low background matrix reduces spectral interferences, making it particularly suitable for trace-level vanadium determinations in complex samples. Each batch includes a comprehensive Certificate of Analysis detailing method validation data, expiration dating, and recommended dilution protocols. The standard’s homogeneous composition ensures consistent performance across analytical runs, while its acidified formulation prevents precipitation or adsorption losses. Designed for laboratories requiring reproducible results in environmental, geological, or industrial testing applications, this standard meets ISO 17034 and ISO Guide 31 requirements for reference material production.
FAQs
1. What is the shelf life of this Vanadium ICP standard when unopened?
The unopened standard maintains its certified concentration for 24 months from the date of manufacture when stored at 15-25°C, protected from light exposure. The expiration date is clearly marked on both the bottle label and Certificate of Analysis.
2. Can this standard be used directly for ICP-OES analysis without dilution?
While the 1000 ppm concentration is suitable for some ICP-OES applications, most methods require dilution to working ranges typically between 0.1-10 ppm. The included COA provides recommended dilution protocols based on common instrumental detection limits and linear ranges.
3. What material are the bottles made from, and are they compatible with organic solvents?
The primary containers are manufactured from high-density polyethylene (HDPE) with polypropylene caps, both of which are resistant to the 2% nitric acid matrix. However, these materials are not recommended for long-term storage of organic solvents as they may absorb or leach compounds.
4. How does the nitric acid concentration affect the standard’s performance?
The 2% nitric acid matrix serves multiple purposes: it stabilizes the vanadium in solution, prevents hydrolysis or precipitation, and matches the acidity of most digested samples. This concentration is optimized to minimize polyatomic interferences in ICP-MS while maintaining compatibility with common sample preparation protocols.
5. What documentation is provided with each bottle for quality assurance?
Each unit includes a multi-page Certificate of Analysis containing: certified concentration with uncertainty, preparation method, traceability statement, homogeneity testing results, stability data, recommended use instructions, and batch-specific QR code linking to additional technical documentation.
