Product Overview
This Lutetium AAS standard solution from Specpure® delivers exceptional purity and consistency for demanding atomic absorption spectroscopy applications. Formulated at a concentration of 1000µg/ml, it provides a reliable reference for trace lutetium quantification in complex matrices. The Specpure® grade ensures minimal interference from contaminants, with rigorous quality control guaranteeing lot-to-lot reproducibility. The aqueous solution is stabilized to prevent precipitation and maintain homogeneity over extended storage periods. Each batch undergoes multi-point calibration verification to meet ISO 17034 and ISO Guide 31 standards, ensuring traceability to NIST reference materials. The solution’s low acidity (typically <5% HNO₃) minimizes matrix effects while maintaining elemental stability. Packaged in HDPE bottles with tamper-evident seals, it resists leaching and external contamination. The 100ml and 500ml pack sizes offer flexibility for both routine laboratory use and high-throughput applications, with the larger volume providing cost-effective scaling for frequent users. The solution’s extended shelf life (24 months unopened) reduces inventory turnover requirements while maintaining analytical performance.
FAQs
1. What is the matrix composition of this Lutetium AAS standard?
The solution is prepared in a dilute nitric acid matrix (typically <5% HNO₃) to ensure complete dissolution and long-term stability of the lutetium ions while minimizing potential interferences in AAS analysis.
2. How does the Specpure® grade differ from standard reagent grades?
Specpure® standards undergo additional purification steps including sub-boiling distillation and specialized filtration to remove particulate and trace metallic contaminants that could affect spectroscopic measurements, resulting in lower detection limits and improved accuracy.
3. What compatibility considerations exist for this standard with different AAS instruments?
This solution is compatible with all flame and graphite furnace AAS systems. For optimal performance with graphite furnace, we recommend a 1:10 dilution to prevent potential matrix effects from the nitric acid content during the charring phase.
4. What are the recommended storage conditions to maintain stability?
Store unopened bottles at 15-25°C in their original packaging, away from direct sunlight and sources of heat. Once opened, tighten the cap immediately after use and consume within 6 months for optimal performance.
5. Are there any known spectral interferences when using this lutetium standard?
The primary spectral interference for lutetium occurs at 336.0nm with ytterbium. We recommend using the alternative 261.5nm line when analyzing samples containing ytterbium, or employing background correction techniques like Zeeman effect or deuterium lamp correction.
