TRM - Ba, Be, Bi, Ce, Co, In, Li, Ni, Pb, U - Aqueous calibration solution ASTASOL® TUNE01

Importance of the topic

Calibration standards are fundamental for accurate quantitative analysis in atomic spectrometry and other analytical methods. High‐quality reference materials ensure traceability, comparability, and reliability of results across laboratories and instruments.

Objectives and Study Overview

This document presents ASTASOL® TUNE01, an aqueous multi‐element calibration solution. It details its composition, uncertainty values, traceability pathway, shelf life, and guidelines for proper handling and use.

Methodology and Instrumentation

ASTASOL® TUNE01 is prepared gravimetrically from ultra‐high‐purity primary compounds and dissolved in 5% sub‐boiled nitric acid and ultrapure water (resistivity ≥18 MΩ·cm). Traceability is established through a chain of calibrations and comparisons involving certified reference materials (CRMs) and techniques including atomic absorption spectrometry (AAS), atomic emission spectrometry (AES), inductively coupled plasma optical emission spectrometry (ICP-OES), and ICP-mass spectrometry (ICP-MS).

Main Results and Discussion

• Assigned concentration for each analyte (Ba, Be, Bi, Ce, Co, In, Li, Ni, Pb, U): 10.0 ± 0.1 mg/L at 20 °C.
• Total trace impurities in the solution do not exceed 0.05 mg/L.
• Homogeneity and stability tests confirm consistent performance over a two‐year shelf life when stored between 5–30 °C.

Benefits and Practical Applications

ASTASOL® TUNE01 provides a reliable calibrator for routine and high‐precision analyses in environmental monitoring, industrial process control, pharmaceutical quality assurance, and research laboratories. It supports a wide range of spectrometric and electroanalytical techniques.

Future Trends and Opportunities

Growing demand for multi‐element reference solutions is driven by emerging applications in nanotechnology, advanced materials, and stringent regulatory monitoring. Future developments may include expanded element panels, matrix‐matched formulations, and lower uncertainty levels through improved certification methods.

Conclusion

ASTASOL® TUNE01 is a well‐characterized, gravimetrically prepared multi‐element calibration solution with robust traceability and stability. When stored and handled according to guidelines, it ensures precise and accurate quantification across diverse analytical techniques.
