Product Overview
This Cerium 10 ppm ICP-ML single-element standard is a high-purity aqueous solution meticulously formulated for inductively coupled plasma mass spectrometry (ICP-MS) and optical emission spectroscopy (ICP-OES) applications. The standard is prepared using ultra-pure cerium metal dissolved in high-quality acids and stabilized in a matrix-matched solution to ensure long-term stability and minimal matrix interference. Each batch undergoes rigorous quality control, including multi-point calibration verification, to guarantee accuracy within ±2% of the stated concentration. The solution is packaged in HDPE bottles with tamper-evident seals to prevent contamination and evaporation, maintaining integrity during storage and transport. Compatible with most ICP instruments, this standard eliminates the need for in-house dilution, saving time while delivering consistent results. The low-particle formulation minimizes nebulizer clogging, and the acid matrix is optimized for compatibility with common sample preparation protocols. Whether used for routine calibration, method validation, or quality control checks, this cerium standard provides the reliability required for critical analytical workflows.
FAQs
1. What is the shelf life of this Cerium 10 ppm standard when unopened?
The unopened standard maintains its specified concentration for 24 months from the date of manufacture when stored at 15-25°C in its original packaging. Always check the label for the exact expiration date as stability may vary slightly between production batches.
2. Can this standard be used with both ICP-MS and ICP-OES instruments?
Yes, the 10 ppm concentration is suitable for both ICP-MS and ICP-OES applications. For ICP-MS, it may require additional dilution depending on your instrument’s linear range, while ICP-OES can typically use it directly for mid-range elemental analysis without further preparation.
3. What acid matrix is used in this Cerium standard solution?
The solution is stabilized in a 2% nitric acid matrix, which is compatible with most ICP sample introduction systems. This matrix helps maintain element solubility while minimizing potential interferences from other acid types that might affect plasma stability.
4. How should I handle potential contamination when using this standard?
Always use dedicated, acid-washed volumetric pipettes or dispensers specifically reserved for standards. Work in a clean environment, preferably under a laminar flow hood if available, and wear powder-free nitrile gloves to prevent trace metal contamination from skin contact or lab dust.
5. What documentation comes with this Cerium standard?
Each bottle includes a comprehensive Certificate of Analysis detailing the exact concentration, uncertainty values, traceability information, batch number, and expiration date. The CoA also specifies the reference materials and analytical methods used for certification, ensuring full compliance with ISO 17025 standards.
