Product Overview
This Specpure® cadmium plasma standard solution delivers exceptional purity and accuracy for demanding analytical applications. Formulated at a precise concentration of 1000µg/ml in a stabilized nitric acid matrix, it ensures reliable calibration and quantification in inductively coupled plasma optical emission spectrometry (ICP-OES) and atomic absorption spectroscopy (AAS). The ultra-high purity grade minimizes matrix interferences, making it suitable for trace-level cadmium analysis in environmental, pharmaceutical, and industrial samples. Each batch undergoes rigorous quality control to guarantee consistency and long-term stability. The solution is packaged in high-density polyethylene bottles to prevent contamination and preserve integrity during storage. Compatible with most standard analytical protocols, this cadmium standard eliminates the need for complex sample preparation, streamlining workflow efficiency. Its low background interference profile enhances detection limits, particularly in complex matrices where cadmium may be present at sub-ppm levels.
FAQs
1. What is the shelf life of this cadmium plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature in its original packaging. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for mercury analysis as well?
No, this solution is specifically formulated for cadmium analysis. For mercury standards, a dedicated mercury plasma standard would be required due to different chemical properties and detection requirements.
3. What is the recommended storage temperature for this product?
Store the unopened solution at 15-25°C in a clean, dry environment away from direct sunlight and incompatible chemicals. Avoid freezing as it may alter the solution’s homogeneity.
4. Does this cadmium standard require any special disposal procedures?
As a heavy metal solution, it should be disposed of according to local hazardous waste regulations. Neutralize with appropriate reagents before disposal if required by your facility’s protocols.
5. How does the Specpure® grade differ from standard analytical grades?
The Specpure® grade undergoes additional purification steps to remove trace impurities that could interfere with ultra-low detection limits, particularly in ICP-OES applications where spectral overlaps are critical.
