Product Overview
This Specpure® Samarium AAS standard solution (1000µg/ml) is engineered for laboratories requiring uncompromising precision in trace metal analysis. Formulated with ultra-high-purity samarium in a stable aqueous matrix, it eliminates matrix interferences to deliver consistent, reproducible results in atomic absorption spectroscopy (AAS) and inductively coupled plasma optical emission spectrometry (ICP-OES). The solution undergoes rigorous quality control, including NIST-traceable certification, to ensure accuracy across calibration curves and quantitative determinations. Its long-term stability minimizes degradation risks, while the Specpure® grade guarantees minimal contaminant levels (<10 ppb for most impurities), making it ideal for low-level detection applications. The 1000µg/ml concentration provides flexibility for serial dilutions without compromising analytical integrity. Housed in HDPE bottles with tamper-evident seals, the solution resists leaching and external contamination, preserving its shelf life under standard lab storage conditions (15–25°C). Compatible with most AAS and ICP instruments, this standard solution reduces recalibration frequency, enhancing workflow efficiency for high-throughput laboratories.
FAQs
1. What is the shelf life of this Specpure® Samarium AAS standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C in its original container. Avoid exposure to direct sunlight or temperature fluctuations.
2. Can this standard be used for ICP-MS applications?
While optimized for AAS and ICP-OES, the ultra-low impurity profile of Specpure® grade makes it suitable for ICP-MS after appropriate dilution. Verify compatibility with your instrument’s detection limits and matrix tolerance.
3. How should I prepare working standards from this 1000µg/ml solution?
Use Class A volumetric glassware and ultra-pure diluents (e.g., 1% HNO₃) for serial dilutions. For example, a 1:100 dilution yields a 10µg/ml working standard. Always recalibrate pipettes before use.
4. What materials are the bottles and caps made of?
The bottles are manufactured from high-density polyethylene (HDPE), and the caps are polypropylene (PP) with a polyethylene-cone liner to prevent leakage and contamination.
5. Is this solution compatible with organic solvents for specific applications?
This aqueous standard is not designed for direct organic solvent use. For organic-phase applications, consider alternative samarium organometallic standards or consult technical support for custom formulations.
