Product Overview

This Thulium AAS standard solution is formulated with Specpure® grade purity, ensuring minimal interference and maximum accuracy in atomic absorption spectroscopy (AAS) applications. The 1000µg/ml concentration provides a robust baseline for calibration curves, dilution series, or direct analysis in trace metal studies. The solution is stabilized in a high-purity acid matrix to prevent precipitation or degradation, guaranteeing long-term stability and consistency in analytical results. Designed for laboratories demanding precision, this standard eliminates background contamination risks, thanks to its ultra-low impurity profile. The aqueous formulation ensures compatibility with most AAS instruments without requiring additional preparation. Whether used for routine quality control or advanced research, this Thulium standard delivers reliable, reproducible data, reducing the need for frequent recalibration. The Specpure® certification confirms adherence to stringent purity benchmarks, making it a trusted choice for critical analytical workflows.

FAQs

1. What is the shelf life of this Thulium AAS standard solution?

The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature in its original container. Always check the label for the exact expiry date.

2. Is this solution compatible with ICP-OES or ICP-MS instruments?

While optimized for AAS, this Thulium standard can be used with ICP-OES or ICP-MS, but dilution may be required to match the instrument’s sensitivity range and avoid matrix effects.

3. What alternatives are available if I need a lower concentration?

Lower concentrations (e.g., 100µg/ml or 10µg/ml) can be prepared by serial dilution using high-purity acids or deionized water, following standard lab protocols for trace metal analysis.

4. How should I store this solution after opening?

After opening, tightly recap the bottle and store it at room temperature (15–25°C) away from direct sunlight. Use within 6 months for optimal accuracy.

5. Does this solution contain any preservatives or stabilizers?

The solution is stabilized with high-purity nitric acid to maintain homogeneity and prevent microbial growth, without added organic preservatives that could interfere with analysis.
