Product Overview

This Yttrium AAS standard solution (1000µg/ml) is formulated with Specpure® grade purity, ensuring exceptional accuracy for atomic absorption spectroscopy applications. The solution is prepared in a stabilized matrix to prevent precipitation and maintain long-term stability, eliminating the need for frequent recalibration. Its ultra-low impurity profile minimizes spectral interferences, making it ideal for trace-level yttrium determinations in complex sample matrices. The solution is supplied in high-density polyethylene (HDPE) bottles with tamper-evident seals to prevent contamination during storage and handling. Each batch undergoes rigorous multi-element analysis via ICP-OES to verify concentration accuracy and purity, with certificates of analysis provided for traceability. The 1000µg/ml concentration offers optimal sensitivity for most AAS instruments while allowing easy dilution for lower-range calibrations. Compatible with both flame and graphite furnace AAS systems, this standard delivers consistent performance across different instrumental configurations. The aqueous formulation ensures complete solubility and homogeneity, critical for reproducible analytical results in research and quality control laboratories.

FAQs

1. What is the shelf life of this Yttrium AAS standard solution when stored properly?

The solution remains stable for 24 months from the date of manufacture when stored unopened at 15-25°C in its original container, protected from light and moisture. Once opened, use within 6 months for optimal accuracy.

2. Can this standard be used with ICP-MS instrumentation, or is it specifically for AAS?

While optimized for AAS applications, this Specpure® grade solution can be used for ICP-MS after appropriate dilution to match the instrument’s linear range, though matrix effects should be evaluated for your specific sample type.

3. What is the typical acid matrix used in this Yttrium standard solution?

The solution is prepared in a dilute nitric acid matrix (typically 2-5% v/v) to ensure complete dissolution of the yttrium and prevent hydrolysis, which is critical for maintaining long-term stability and accuracy.

4. How does the Specpure® grade differ from standard analytical grades for AAS standards?

Specpure® grade undergoes additional purification steps to remove trace metallic and anionic impurities that could interfere with spectral analysis, particularly at ppb levels, resulting in lower detection limits and improved method sensitivity.

5. What precautions should be taken when handling this high-concentration Yttrium standard?

Always use appropriate PPE including nitrile gloves and safety goggles, as the solution contains nitric acid. Work in a fume hood when preparing dilutions, and avoid skin contact to prevent potential irritation from the acid matrix.
