Product Overview
This Selenium 1000 ppm ICP-ML single-element standard is a high-purity aqueous solution meticulously formulated for inductively coupled plasma mass spectrometry (ICP-MS) applications. Designed to deliver exceptional accuracy and reproducibility, it is prepared using ultra-pure selenium in a stabilized matrix to prevent precipitation or degradation over time. The standard is traceable to NIST (National Institute of Standards and Technology) reference materials, ensuring compliance with international quality benchmarks for analytical laboratories. Its low background interference and consistent concentration make it ideal for calibration curves, method validation, and routine quality control in trace metal analysis. The solution is packaged in high-density polyethylene (HDPE) bottles to minimize contamination risks, with tamper-evident seals for integrity assurance. Compatible with most ICP-MS and ICP-OES instruments, this standard eliminates the need for in-house dilution in many applications, saving time while maintaining precision. The extended shelf life under recommended storage conditions (2-8°C) further enhances its cost-effectiveness for frequent lab use.
FAQs
1. What is the shelf life of this Selenium 1000 ppm ICP standard?
The standard remains stable for 24 months from the date of manufacture when stored unopened at 2-8°C. Once opened, use within 6 months for optimal accuracy.
2. Is this standard compatible with both ICP-MS and ICP-OES instruments?
Yes, the 1000 ppm concentration is suitable for both ICP-MS and ICP-OES applications, though you may need to dilute it further for ICP-MS depending on your instrument’s sensitivity requirements.
3. What is the matrix composition of this Selenium standard?
The solution uses a nitric acid matrix (typically 2-5% v/v) to ensure stability and prevent selenium precipitation, making it compatible with most acid digestion protocols.
4. Can this standard be used for environmental water testing?
While primarily designed for instrumental calibration, it can serve as a spike solution for environmental water testing when properly diluted to match expected sample concentrations.
5. How should I dispose of unused Selenium standard solution?
Follow your institution’s chemical waste disposal protocols. As a heavy metal solution, it should be collected in designated hazardous waste containers and never poured down drains.
