Product Overview
The Cerium 10000 ppm ICP single-element standard is a high-purity reference material designed for precise calibration in inductively coupled plasma (ICP) spectroscopy. Formulated in a 2% nitric acid matrix, this standard ensures stability and compatibility with most ICP instruments, minimizing matrix interference during analysis. The 10000 ppm (1%) concentration provides optimal sensitivity for both ICP-OES and ICP-MS applications, allowing for accurate quantification of cerium in diverse sample matrices. Traceability to NIST (National Institute of Standards and Technology) guarantees reliability, making it suitable for laboratories requiring ISO 17025 compliance or GLP (Good Laboratory Practice) adherence. The standard is packaged in a 100 ml HDPE bottle with a tamper-evident seal to prevent contamination and ensure long-term stability. Its low background impurity levels (<10 ppb for most common interferents) further enhance detection limits, while the acidified matrix prevents precipitation, ensuring homogeneous distribution of the element. This product is ideal for routine calibration, method validation, or quality control in analytical workflows where cerium determination is critical.
FAQs
1. What is the shelf life of this Cerium ICP standard?
The shelf life is 24 months from the date of manufacture when stored unopened at room temperature (15–25°C). Once opened, use within 6 months for optimal accuracy.
2. Is this standard compatible with organic solvents?
No, this standard is formulated in an aqueous nitric acid matrix. For organic solvent compatibility, consider a standard specifically designed for organic matrices or dilute appropriately with caution.
3. Can this be used for AAS (Atomic Absorption Spectroscopy)?
While primarily designed for ICP, it can be used for AAS if diluted to the appropriate concentration range for your instrument’s linear dynamic range. Verify matrix compatibility with your AAS method.
4. What is the typical uncertainty of this standard?
The expanded uncertainty (k=2) is ≤1%, as certified on the Certificate of Analysis. This accounts for homogeneity, stability, and characterization contributions.
5. How should I dispose of unused standard?
Neutralize with a base (e.g., sodium hydroxide) to pH 6–8 before disposal according to local regulations for heavy metal-containing laboratory waste. Never dispose of untreated.
