CRM Yttrium (Y) - Aqueous calibration solution ASTASOL® AN90671N

Significance of the topic

Certified reference materials (CRMs) such as ASTASOL® AN90671N play a critical role in ensuring accurate calibration and validation of analytical methods. Reliable reference solutions are essential for traceable quantification of elements in various matrices, supporting quality assurance in environmental monitoring, pharmaceutical testing, and industrial process control.

Study objectives and overview

This certificate describes the production, certification and key characteristics of an aqueous yttrium calibration solution (ASTASOL® AN90671N). The main goals are to provide a traceable concentration value, demonstrate homogeneity and stability, and detail intended uses and storage conditions.

Used methodology and instrumentation

• Gravimetric preparation for direct SI traceability (kg basis).
• Verification by complexometric titration against NIST SRM 928.
• Independent confirmation of yttrium concentration using NIST SRM 3167a.
• Evaluation of trace impurities by atomic absorption spectrometry (AAS), inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS).

Main results and discussion

The CRM contains yttrium at a certified mass concentration of 1 000 mg/L (±2 mg/L, k=2) in a 2% HNO3 matrix; corresponding mass fraction is 984 mg/kg (±3 mg/kg). Density at 20 °C is 1.0161 g/cm3 (±0.0005). Trace elements were largely below detection limits; notable detectable impurities include calcium (0.15 mg/L) and iron (0.002 mg/L), while the majority of other monitored elements remain under their respective limits of quantification.

Benefits and practical applications

ASTASOL® AN90671N enables precise calibration of atomic spectrometric techniques (AAS, AES, ICP-OES, ICP-MS), molecular absorption and certain electroanalytical methods. Its high purity and well-characterized uncertainty support robust method validation, inter-laboratory comparisons, and compliance with regulatory standards.

Future trends and opportunities

Advancements in CRM development focus on multi-element solutions, lower detection limits for emerging contaminants, and digital certification via blockchain for enhanced traceability. Integration with laboratory information management systems (LIMS) and adoption of automation can further streamline CRM utilization and data integrity.

Conclusion

ASTASOL® AN90671N is a high-quality yttrium reference solution providing reliable calibration and validation support for diverse analytical platforms. Its rigorous certification and clear handling instructions ensure consistent performance across laboratories.
