TRM Al, As, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Se, Sr, Ti, Tl, V, Zn - Aqueous calibration solution ASTASOL® ASTASOL® ANM010

Significance of the Topic

Reliable multi-element calibration standards are essential for accurate quantification in modern analytical chemistry. The availability of a certified reference solution containing traceable concentrations of numerous elements simplifies method calibration across atomic spectrometric and other techniques.

Objectives and Study Overview

This Identification Sheet describes the preparation, certification, and recommended use of the ASTASOL® ANM010 aqueous calibration solution, designed to deliver consistent 100 mg/L concentrations (±0.5 mg/L, k=2) for 26 analytes in a 5 % HNO3 matrix.

Methodology

The solution was gravimetrically prepared from high-purity primary compounds (purities ≥ 99.5 %) and sub-boiling distilled nitric acid in ultrapure water (≥ 18 MΩ·cm, 0.22 μm filtered). Traceability was established through an unbroken calibration chain using certified reference materials (AN 9002–AN 9069) and primary analytical methods.

Used Instrumentation

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

Main Results and Discussion

All 26 elements (Al, As, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Se, Sr, Ti, Tl, V, Zn) achieved certified concentrations of 100 mg/L with expanded uncertainty ±0.5 mg/L at 20 °C. Trace impurities are maintained below 0.2 mg/L total. Homogeneity and stability assessments confirm consistent performance over a 5-year shelf life (12 months post-opening under specified storage conditions).

Benefits and Practical Uses

The ASTASOL® ANM010 standard streamlines calibration workflows by providing a single multi-element solution, reducing preparation errors and ensuring compliance with quality management systems (ISO 9001, ISO/IEC 17025, ISO 17034). It supports quantitative analysis by AAS, AES, ICP-OES, ICP-MS, molecular absorption, and selected electroanalytical methods.

Future Trends and Applications

Future developments may include expanding element coverage to meet emerging analytical needs, formulating lower concentration ranges for ultra-trace determinations, integrating with automated dilution and sample introduction systems, and enhancing digital traceability and real-time calibration monitoring. Adaptation for miniaturized and field-deployable sensor platforms is also anticipated.

Conclusion

ASTASOL® ANM010 provides a robust, certified multi-element calibration solution with proven traceability, homogeneity, and stability. Its broad applicability and consistent performance support high-precision measurements in research, quality control, and industrial laboratories.
