Form – Liquid
Grade – ICP-ML (Inductively Coupled Plasma-Mass Spectrometry)
Application – Trace metal analysis, calibration, quality control
Product Overview
The Cobalt 10 ppm ICP-ML single-element standard is a high-purity liquid solution meticulously prepared for precise trace metal analysis in laboratory settings. Formulated using ultra-pure reagents and deionized water, this standard ensures minimal matrix interference, making it ideal for inductively coupled plasma-mass spectrometry (ICP-MS) applications. The 10 ppm concentration provides an optimal balance between sensitivity and linearity, allowing for accurate calibration curves and reliable quantification of cobalt in diverse sample matrices. Packaged in a 100 ml high-density polyethylene (HDPE) bottle, the solution maintains stability over extended periods when stored under recommended conditions. The standard undergoes rigorous quality control testing to verify concentration accuracy, homogeneity, and absence of contaminants, ensuring consistent performance in analytical workflows. Its compatibility with most ICP-MS instruments eliminates the need for additional sample preparation, streamlining laboratory processes while maintaining data integrity. The liquid form facilitates easy dilution and handling, reducing the risk of cross-contamination during routine laboratory operations.
FAQs
1.
What is the shelf life of this Cobalt 10 ppm ICP-ML standard?
The standard remains stable for 24 months from the date of manufacture when stored unopened at room temperature, away from direct sunlight and moisture. Once opened, use within 6 months for optimal accuracy. 2.
Is this standard compatible with ICP-OES instruments?
While primarily designed for ICP-MS applications, this 10 ppm Cobalt standard can be used with ICP-OES instruments, though you may need to adjust the concentration range to match your specific detection limits and calibration requirements. 3.
What materials are used in the packaging to prevent contamination?
The solution is packaged in a high-density polyethylene (HDPE) bottle with a polypropylene (PP) screw cap, both of which are tested for trace metal leaching to ensure minimal risk of contamination during storage. 4.
Can this standard be used for environmental sample analysis?
Yes, the high purity and certified concentration make it suitable for environmental analysis, including water, soil, and sediment samples, provided the matrix effects are properly accounted for during sample preparation. 5.
How should I dispose of unused or expired Cobalt standard?
Follow local regulations for chemical waste disposal. Typically, small quantities can be neutralized and disposed of as hazardous waste, while larger volumes may require professional hazardous waste handling services.
