Product Overview

This Specpure® alkali metals plasma standard solution delivers unmatched precision for spectroscopic applications, featuring a certified concentration of 100µg/ml for barium (Ba), beryllium (Be), calcium (Ca), cesium (Cs), potassium (K), lithium (Li), magnesium (Mg), sodium (Na), rubidium (Rb), and strontium (Sr). Engineered for compatibility with ICP-OES and atomic absorption spectrometry (AAS), the solution ensures minimal matrix interference and exceptional stability, eliminating the need for frequent recalibration. The ultra-high-purity grade adheres to stringent quality controls, with traceability to NIST standards, guaranteeing reliable quantification of alkali and alkaline earth metals in complex samples. Its aqueous formulation resists contamination and degradation, extending shelf life while maintaining consistency across batches. Ideal for laboratories requiring reproducible results in environmental, geological, or industrial testing, this standard solution reduces variability and enhances analytical confidence. The 100ml and 500ml pack sizes cater to both high-throughput and low-volume workflows, offering flexibility without compromising accuracy. Each bottle undergoes rigorous testing for homogeneity and concentration accuracy, ensuring compliance with ISO 17025 guidelines for reference materials.

FAQs

1. What is the shelf life of this alkali metals plasma standard solution?

The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C. Once opened, use within 6 months for optimal performance.

2. Can this standard be used for ICP-MS analysis?

While optimized for ICP-OES and AAS, it may require additional dilution for ICP-MS due to higher sensitivity. Verify compatibility with your instrument’s detection limits.

3. Are there any known interferences with other elements in this solution?

The Specpure® grade minimizes interferences, but spectral overlaps may occur with high concentrations of transition metals. Consult your instrument’s software for correction algorithms.

4. How should I dispose of unused or expired solution?

Follow local regulations for hazardous chemical disposal. Neutralize with dilute acid if required, then dispose via authorized waste management services.

5. Is a certificate of analysis (COA) provided with each batch?

Yes, every batch includes a COA detailing concentration values, uncertainty, expiration date, and traceability to NIST standards for quality assurance.
