Product Overview
This Samarium 10 ppm ICP-ML single-element standard delivers exceptional purity and stability for demanding trace metal analysis applications. Formulated in a 2% nitric acid matrix, the solution maintains homogeneity and minimizes matrix interferences during ICP-OES or ICP-MS measurements. The concentration is certified at 10 ± 0.2 ppm with NIST-traceable reference materials, ensuring reliable calibration curves and quantitative accuracy. Packaged in HDPE bottles with tamper-evident seals, the standard resists contamination while providing long-term stability when stored properly. The low-particle formulation prevents nebulizer clogging in ICP systems, while the acidified matrix maintains element solubility across storage conditions. Each batch undergoes multi-point verification for concentration accuracy and potential interferences, with certificates of analysis provided for full traceability. The solution’s compatibility with most ICP sample introduction systems makes it versatile for both routine and research-grade applications requiring precise samarium quantification.
FAQs
1. What is the exact matrix composition of this Samarium standard?
The standard is prepared in 2% high-purity nitric acid (HNO₃) using Type I water, with residual acidity carefully controlled to maintain element stability without introducing matrix effects during analysis.
2. How should this standard be stored to maintain its certified concentration?
Store unopened at 15-25°C in the original container, protected from direct sunlight. Once opened, keep tightly sealed and use within 12 months for optimal accuracy, though the solution remains stable for up to 24 months when properly stored.
3. Is this standard compatible with both ICP-OES and ICP-MS instruments?
Yes, the 10 ppm concentration and nitric acid matrix are optimized for both ICP-OES and ICP-MS applications, though you may need to dilute for ICP-MS depending on your instrument’s linear range and detection limits.
4. What materials are used for the bottle and cap to prevent contamination?
The standard comes in HDPE (high-density polyethylene) bottles with PP (polypropylene) caps, both pre-cleaned with ultra-pure acids to minimize leachable metals and organic contaminants that could affect trace analysis.
5. Can this standard be used for preparing multi-element calibration solutions?
While designed as a single-element standard, it can be combined with other compatible single-element standards to create custom multi-element solutions, provided all components share similar matrix requirements and stability profiles.
