Product Overview

This Tantalum AAS standard solution (1000µg/ml) from Specpure® delivers exceptional purity and consistency for demanding analytical applications. Formulated with ultra-low impurity levels, it meets stringent requirements for atomic absorption spectroscopy (AAS), inductively coupled plasma optical emission spectrometry (ICP-OES), and other trace metal analyses. The solution is stabilized to prevent precipitation and degradation, ensuring long-term accuracy in calibration curves and quantitative measurements. Each batch undergoes rigorous quality control, including multi-element impurity testing via ICP-MS, to guarantee traceability and reproducibility. The aqueous matrix is optimized for compatibility with common dilution protocols, eliminating matrix interference risks. Packaged in high-density polyethylene (HDPE) bottles to minimize leaching, the solution maintains its integrity during storage and handling. Whether used as a primary standard or for routine lab calibration, this Specpure®-grade tantalum solution provides the precision required for research-grade analyses, industrial quality control, or environmental testing.

FAQs

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

The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C. Once opened, use within 6 months for optimal accuracy.

2. Is this solution compatible with ICP-MS instrumentation?

While primarily designed for AAS, the ultra-high purity of Specpure® standards makes it suitable for ICP-MS after appropriate dilution to match instrument sensitivity ranges.

3. Are there lower concentration alternatives available for this product?

Dilution from this 1000µg/ml stock is recommended for lower concentrations. Pre-diluted standards may be available upon request for specific applications.

4. How should I store this solution to prevent contamination?

Store upright in the original HDPE bottle at room temperature (15–25°C). Avoid exposure to direct sunlight or temperature fluctuations. Use clean, dedicated pipettes to prevent cross-contamination.
