Product Overview
This 1000 ppm Magnesium ICP-ML single-element standard delivers exceptional accuracy for spectroscopic analysis, formulated with ultra-high-purity magnesium in a stabilized aqueous matrix. The solution is rigorously tested for homogeneity and long-term stability, ensuring consistent performance across ICP-OES, ICP-MS, and AAS instrumentation. Each batch undergoes multi-point calibration verification against NIST-traceable reference materials, eliminating matrix interference risks. The low-acid formulation minimizes instrument corrosion while maintaining elemental integrity during storage. Housed in HDPE bottles with tamper-evident seals, the standard resists contamination and evaporation. The concentration is certified with ±1% tolerance, backed by comprehensive COA documentation including lot-specific stability data. Compatible with most autosamplers, this standard requires no additional dilution for routine calibration curves. The proprietary stabilizer system prevents precipitation or microbial growth, extending shelf life to 24 months under proper storage conditions. Ideal for laboratories requiring reproducible magnesium quantification in environmental, pharmaceutical, or material science applications.
FAQs
1. What is the matrix composition of this magnesium standard?
The standard uses a dilute nitric acid matrix (2% v/v) with proprietary stabilizers to maintain elemental integrity and prevent microbial growth during storage.
2. Can this standard be used for both ICP-OES and ICP-MS analysis?
Yes, the 1000 ppm concentration is optimized for direct use in ICP-OES while allowing precise dilution for ICP-MS applications without introducing contaminants.
3. What documentation is provided with each batch?
Every bottle includes a Certificate of Analysis with lot-specific data: certified concentration, expiration date, homogeneity test results, and NIST traceability information.
4. How should this standard be stored to maintain accuracy?
Store upright at 15-25°C in the original container, tightly sealed. Avoid exposure to direct sunlight or temperature fluctuations above 30°C.
5. Are there any known interferences with this magnesium standard?
The formulation is tested for over 50 potential interferents. Only high concentrations of aluminum (>5000 ppm) may require matrix matching in ICP analysis.
