Product Overview
This Specpure® Tellurium plasma standard solution delivers exceptional purity and accuracy for demanding analytical applications. Formulated at a precise 10µg/ml concentration, it ensures reliable calibration and quantification in plasma-based techniques like ICP-OES and AAS. The solution is prepared using ultra-high purity Tellurium (Te) in a stabilized matrix, minimizing interference and background noise for superior sensitivity. Each 100ml batch undergoes rigorous quality control to guarantee consistency, making it ideal for laboratories requiring trace-level detection. The Specpure® grade ensures minimal contamination, with impurities controlled to sub-ppb levels, while the aqueous formulation offers excellent stability and homogeneity. Designed for long-term storage, this standard maintains its integrity when stored under recommended conditions, providing reproducible results over extended periods. Its compatibility with most plasma spectrometry systems eliminates the need for additional sample preparation, streamlining workflow efficiency.
FAQs
1. What is the shelf life of this Tellurium plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature (15-25°C) and protected from light. Once opened, use within 6 months for optimal accuracy.
2. Is this standard compatible with ICP-MS instrumentation?
While primarily designed for ICP-OES and AAS, this standard can be used with ICP-MS after appropriate dilution to match the instrument’s dynamic range, as the 10µg/ml concentration may exceed typical ICP-MS calibration limits.
3. What matrix is used in this Specpure® Tellurium standard?
The solution is prepared in a dilute nitric acid matrix (typically 2-5% HNO₃), which ensures stability and compatibility with most plasma spectrometry systems without requiring additional acidification.
4. Can this standard be used for environmental water analysis?
Yes, the ultra-low impurity profile and stabilized matrix make it suitable for environmental applications, including water analysis, provided the sample matrix is matched during calibration to account for potential interferences.
5. How does the Specpure® grade differ from standard analytical grades?
Specpure® standards undergo additional purification steps to reduce trace impurities to sub-ppb levels, offering superior accuracy for ultra-trace analysis compared to conventional analytical grades, which may contain higher background contamination.
