Product Name – Chromium, plasma standard solution, Specpure®, Cr 10,000 μg/ml Quantity/Pack Size – 50ml, 100ml, 500ml Form – Liquid (aqueous solution) Grade – Specpure® (ultra-high purity) Application – ICP-OES, AAS, trace metal analysis
Product Overview
This Specpure® chromium plasma standard solution delivers exceptional purity and accuracy for demanding analytical applications. Formulated at a precise 10,000 μg/ml concentration, it ensures reliable calibration and quantification in trace metal analysis. The ultra-high purity grade minimizes matrix interferences, making it ideal for techniques like ICP-OES and AAS where sensitivity and precision are critical. The aqueous solution is stabilized to maintain long-term integrity, reducing the risk of precipitation or concentration shifts over time. Each batch undergoes rigorous quality control to guarantee consistency, with certification of analysis provided for traceability. The solution is packaged in high-density polyethylene bottles to prevent contamination and leaching, ensuring sample integrity from storage to use. Its broad compatibility with common laboratory solvents and matrices makes it versatile for various sample preparation workflows. The high concentration allows for easy dilution to working standards, reducing preparation time while maintaining accuracy. This chromium standard is particularly valuable in environmental testing, metallurgical analysis, and clinical research where chromium levels must be precisely determined.
FAQs
1. What is the shelf life of this chromium plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for ICP-MS analysis?
While primarily designed for ICP-OES and AAS, it can be used for ICP-MS with proper dilution to avoid instrument saturation from the high concentration.
3. What dilution solvent is recommended for preparing working standards?
Ultra-pure deionized water (18.2 MΩ·cm) is recommended for dilution to maintain the solution’s integrity and prevent contamination.
4. Is this chromium standard compatible with organic solvents?
The aqueous solution is not directly miscible with most organic solvents. For organic matrices, consider evaporating the aqueous portion and reconstituting in the desired solvent.
5. How should I dispose of unused chromium standard solution?
Follow local regulations for heavy metal waste disposal. The solution should be collected in designated hazardous waste containers and processed by authorized waste handlers.
