TRM - Ba, Bi, Ce, Co, In, Li, U - Aqueous calibration solution ASTASOL® TUNE08P

Importance of the topic

Certified multi-element calibration solutions are foundational to precise quantitative analysis in atomic and molecular spectrometry as well as electroanalysis. Providing traceable, well-characterized reference materials ensures measurement accuracy, supports regulatory compliance, and enhances comparability of results across laboratories.

Study objectives and overview

This identification sheet describes the development and characterization of ASTASOL® TUNE08P, an aqueous calibration solution containing seven trace elements. The primary goal is to document its composition, assign certified concentrations with uncertainties, and outline its intended analytical use.

Applied methodology and instrumentation

The solution is prepared gravimetrically from high-purity primary compounds and diluted in an acidified matrix (2% HNO₃, 0.5% HCl). Traceability is established through comparison with NIST-traceable certified reference materials (CRMs) using techniques such as:

• Atomic Absorption Spectrometry (AAS)
• Atomic Emission Spectrometry (AES)
• Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)
• Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

The homogeneity and stability of the solution were evaluated to guarantee performance over the declared shelf life.

Main results and discussion

Cerium, barium, bismuth, cobalt, indium, lithium and uranium are each certified at 1.00 µg/L with an expanded uncertainty of ± 0.05 µg/L (k=2) at 20 °C. Trace contaminant levels remain below 0.02 µg/L total. The product demonstrates uniform composition and stable concentrations when stored between 5 – 30 °C and handled according to instructions.

Benefits and practical applications

This multi-element calibrator is suitable for routine calibration and validation of analytical workflows in environmental monitoring, pharmaceutical testing, food safety, and material research. Use in atomic spectrometric and selected electroanalytical methods enhances data reliability and supports quality assurance measures.

Future trends and potential applications

Emerging analytical demands include ultra-trace analysis and high-throughput screening. Development of matrix-matched CRMs, automation-friendly formats, and expanded element panels will address evolving industry needs and further reduce measurement uncertainty.

Conclusion

ASTASOL® TUNE08P offers a robust, traceable calibration solution for multiple analytical techniques. Its rigorous characterization, ease of use, and certified uncertainty values make it a valuable tool for laboratories seeking dependable quantitative results.
