Product Overview
This Specpure® lithium plasma standard solution delivers exceptional purity and consistency for demanding analytical applications. Formulated at a precise concentration of 10,000µg/ml in an ultra-clean matrix, it serves as a reliable calibration reference for inductively coupled plasma optical emission spectroscopy (ICP-OES) and atomic absorption spectroscopy (AAS). The solution is manufactured under stringent quality controls to ensure minimal matrix interference and maximum stability, with traceability to NIST standards where applicable. Its low background contamination makes it particularly suitable for trace-level lithium determinations in complex sample matrices. The aqueous formulation eliminates solubility issues while maintaining long-term stability when stored properly. Each batch undergoes rigorous multi-element purity testing to guarantee interference-free performance in high-sensitivity analyses. The solution’s uniform composition ensures reproducible results across multiple analytical runs, reducing the need for frequent recalibration. Its compatibility with most standard plasma instrumentation makes it a versatile choice for laboratories requiring high-precision lithium quantification.
FAQs
1. What is the shelf life of this lithium plasma standard solution?
The solution maintains its certified concentration for 24 months from the date of manufacture when stored unopened at room temperature. Once opened, we recommend using within 6 months for optimal accuracy.
2. Can this standard be used for flame AAS applications?
Yes, this lithium standard is fully compatible with flame atomic absorption spectroscopy, though you may need to dilute it to match your instrument’s optimal working range for lithium analysis.
3. What dilution factors are typically used with this 10,000µg/ml standard?
Common dilution ranges depend on your detection limits, but many laboratories prepare working standards between 1-100µg/ml by serial dilution using appropriate acid matrices to match sample composition.
4. How should I handle potential contamination when using this standard?
Always use dedicated, acid-washed volumetric glassware and pipettes to prevent cross-contamination. The solution’s purity makes it particularly sensitive to external lithium sources in laboratory environments.
5. What documentation comes with each bottle of this standard?
Every unit includes a comprehensive certificate of analysis detailing the exact lithium concentration, trace impurity profile, expiration date, and recommended storage conditions for full traceability.
