Product Overview
This Scandium 1000 ppm ICP-ML single-element standard is meticulously formulated to deliver unmatched precision in trace elemental analysis. The solution is prepared in a high-purity matrix, ensuring minimal interference and maximum stability for ICP-MS applications. Each batch undergoes rigorous quality control to guarantee accuracy, with traceability to NIST or equivalent reference materials. The 1000 ppm concentration provides an optimal balance for calibration curves, reducing dilution errors while maintaining sensitivity. Packaged in a 100 ml HDPE bottle with tamper-evident sealing, it resists contamination and preserves integrity during storage. The liquid form ensures homogeneous distribution, eliminating settling or segregation issues common in powdered standards. Compatible with most ICP-MS systems, this standard is ideal for laboratories requiring consistent, reproducible results in routine or high-throughput analysis. Its long shelf life under recommended conditions minimizes waste, offering cost-efficiency without compromising performance.
FAQs
1. What matrix is used for this Scandium ICP-ML standard?
The standard is prepared in a dilute nitric acid matrix (typically 2-5% HNO₃) to ensure compatibility with ICP-MS instrumentation and prevent precipitation or adsorption losses.
2. Can this standard be used for ICP-OES applications?
While optimized for ICP-MS, the 1000 ppm concentration is suitable for ICP-OES after appropriate dilution, though matrix effects should be evaluated for your specific instrument and method.
3. What is the typical uncertainty or tolerance for the 1000 ppm concentration?
The concentration tolerance is ±2% relative, with uncertainty documented in the included Certificate of Analysis, traceable to primary reference materials.
4. How should this standard be stored to maintain stability?
Store unopened at 15–25°C in the original bottle, away from direct sunlight and sources of contamination. Once opened, reseal tightly and use within 12 months for optimal performance.
5. Are there lower-concentration Scandium standards available for calibration curves?
This 1000 ppm stock is designed for serial dilution to prepare working standards; pre-diluted lower concentrations (e.g., 10 ppm, 100 ppm) may be available as separate products.
