Product Overview
This Specpure® Samarium plasma standard solution delivers exceptional purity (1000µg/ml Sm) in a stabilized nitric acid matrix, engineered for high-accuracy instrumental analysis. The ultra-low impurity profile ensures minimal spectral interference, making it ideal for calibration curves in ICP-OES, ICP-MS, and atomic absorption (AA) spectroscopy. Each batch undergoes rigorous multi-element analysis to guarantee consistency, with certified concentrations traceable to NIST standards. The solution’s homogeneous composition eliminates settling risks, while the acid matrix prevents precipitation or adsorption losses during storage. Compatible with most autosamplers and nebulizers, this standard maintains stability for 24+ months when stored at 15-25°C in its original amber glass bottle. The Specpure® grade designation signifies <10 ppb combined impurity levels for critical interfering elements, with individual contaminants (like Fe, Cu, Pb) maintained below 1 ppb. For laboratories requiring ultra-trace detection limits, this samarium standard provides the linear response and reproducibility needed for environmental, geological, or materials science applications where parts-per-billion sensitivity is non-negotiable.
FAQs
1. What is the matrix composition of this samarium standard solution?
The solution uses a 2-5% v/v ultrapure nitric acid matrix, optimized for plasma stability and minimal polyatomic interference during analysis.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the 1000µg/ml concentration is suitable for both techniques, though dilution may be required for ICP-MS to avoid detector saturation at higher concentrations.
3. What is the shelf life after opening the bottle?
When stored at 15-25°C in the original tightly sealed amber bottle, the solution remains stable for 24 months from the date of manufacture, even after opening.
4. Are there any known spectral overlaps with this samarium standard?
Samarium’s primary emission lines (359.260 nm, 442.434 nm) are free from major overlaps, but secondary lines may interfere with europium or gadolinium in complex matrices.
5. How does this compare to single-element standards from other brands?
The Specpure® grade offers <10 ppb total impurities versus typical 50-100 ppb in standard-grade solutions, with tighter lot-to-lot consistency for calibration curves.
