Product Overview
The Selenium 10 ppm ICP-ML single-element standard is a high-purity, matrix-matched solution designed for precise trace analysis in inductively coupled plasma mass spectrometry (ICP-MS) and optical emission spectroscopy (ICP-OES). Formulated with ultra-low contamination risk, this standard ensures reliable calibration and quantification of selenium in diverse sample matrices, including environmental, biological, and industrial materials. The 10 ppm concentration provides an optimal balance for sensitivity and linearity in analytical workflows, while the aqueous matrix minimizes interferences for consistent performance. Each batch undergoes rigorous quality control, including multi-point verification against NIST-traceable reference materials, to guarantee accuracy and reproducibility. The solution is stabilized to prevent precipitation or degradation over time, ensuring long-term stability when stored under recommended conditions. Compatible with most ICP instruments, this standard eliminates the need for complex sample preparation, reducing workflow variability. Whether used for routine calibration, method validation, or research applications, this Selenium standard delivers the precision demanded by modern analytical laboratories.
FAQs
1. What is the shelf life of this Selenium 10 ppm ICP-ML standard?
The standard remains stable for 24 months from the date of manufacture when stored unopened at 15-25°C in its original container. Once opened, use within 6 months for optimal performance.
2. Can this standard be used for both ICP-MS and ICP-OES applications?
Yes, the 10 ppm concentration is suitable for both ICP-MS and ICP-OES, though you may need to dilute it further for ICP-OES depending on your instrument’s sensitivity requirements.
3. What is the matrix composition of this Selenium standard?
The standard is prepared in a dilute nitric acid matrix (typically 2-5% v/v HNO₃) to ensure complete dissolution and stability of the selenium while minimizing potential interferences.
4. How should I handle potential contamination when using this standard?
Use dedicated, acid-washed volumetric pipettes and containers to prevent cross-contamination. Always wear appropriate PPE, including nitrile gloves, as selenium compounds can be hazardous.
5. Is this standard traceable to international reference materials?
The concentration is verified against NIST-traceable reference materials, with certification documentation provided for each batch to ensure metrological traceability.
