Importance of the topic

Aqueous calibration solutions traceable to SI units are crucial for reliable quantification in atomic spectrometry. They ensure measurement accuracy across laboratories and support quality control procedures in environmental, pharmaceutical, and industrial analyses.

Objectives and overview of the study

This identification sheet describes the composition, traceability, and performance characteristics of the ASTASOL® TUNE06 multi-element calibration solution produced by ANALYTIKA. It provides end users with essential information on preparation, homogeneity, stability, and intended analytical applications.

Methodology and instrumentation used

• Gravimetric preparation using high-purity starting compounds (≥99.5%) for 69 elements.
• Matrix formulation: 2% HNO₃ in ultrapure water with traces of HF.
• Traceability established through certified reference materials (AN Series CRMs) and NIST SRMs via atomic spectrometric techniques (AAS, AES, ICP-OES, ICP-MS).

Main results and discussion

Each analyte is assigned a concentration of 50.0 ± 0.5 µg/L (k=2) at 20 °C. Homogeneity studies and stability tests demonstrate uniform element distribution and one-year shelf life under defined storage conditions. Total trace impurities remain below 0.3 µg/L, confirming high purity.

Benefits and practical applications

• Provides a convenient multi-element standard for calibration of spectrometric and selected electroanalytical methods.
• Reduces preparation time and potential errors compared to single-element standards.
• Supports environmental monitoring, clinical testing, and regulatory compliance with traceability requirements.

Future trends and possibilities

Emerging developments may include custom concentration ranges down to sub-µg/L levels, digital certification for real-time traceability, and adaptation for advanced techniques such as single-particle ICP-MS and laser ablation analysis.

Conclusion

ASTASOL® TUNE06 is a rigorously characterized multi-element calibration solution combining precise concentration assignment, proven homogeneity, and stability. It meets diverse analytical demands and enhances measurement confidence across laboratories.
