Product Overview
The Tellurium 10000 ppm ICP single-element standard is a high-purity reference solution designed for precise elemental quantification in analytical laboratories. Formulated with ultra-pure reagents and stabilized in a nitric acid matrix, this standard ensures long-term stability and minimal matrix interference during analysis. The 10000 ppm (1% w/v) concentration provides optimal sensitivity for ICP-OES and ICP-MS instrumentation while maintaining linear calibration across multiple dilution ranges. Each batch undergoes rigorous quality control testing to verify concentration accuracy, with traceability to NIST-certified reference materials. The solution is packaged in HDPE bottles with tamper-evident seals to prevent contamination and ensure sample integrity. Its low background impurity profile makes it particularly suitable for trace-level determinations in environmental, geological, and industrial samples. The standard’s homogeneous composition eliminates the need for pre-digestion, saving preparation time while maintaining analytical precision. Compatible with most atomic spectroscopy systems, this Tellurium standard delivers consistent performance across various analytical protocols.
FAQs
1. What is the shelf life of this Tellurium ICP standard when stored properly?
When stored unopened at room temperature in its original container, this standard maintains its specified concentration for 24 months from the date of manufacture. Once opened, we recommend using within 12 months for optimal accuracy.
2. Can this standard be used directly for ICP-MS analysis without further dilution?
The 10000 ppm concentration is typically too high for direct ICP-MS analysis and requires dilution. Most applications will need dilution to the ppb or low ppm range depending on your instrument’s linear range and the specific analytical requirements.
3. What materials are used for the bottle and cap to ensure sample integrity?
The solution is packaged in high-density polyethylene (HDPE) bottles with polypropylene caps, both of which are resistant to the nitric acid matrix and minimize potential leaching of contaminants that could interfere with analysis.
4. How does the nitric acid concentration in this standard affect its compatibility with different instruments?
The standard contains approximately 2-5% nitric acid, which is compatible with most ICP systems. However, for instruments sensitive to acid concentrations, you may need to match the acid content of your samples or perform appropriate matrix matching during calibration.
5. What quality control measures are implemented during production of this standard?
Each batch undergoes multi-point quality control including gravimetric preparation verification, ICP-OES cross-checking, and stability testing. The production follows ISO 17034 and ISO/IEC 17025 guidelines with traceability to NIST SRMs for concentration accuracy.
