Product Overview
This Gadolinium plasma standard solution from Specpure® delivers exceptional purity and consistency for demanding analytical applications. Formulated at a concentration of 10,000µg/ml in a nitric acid matrix, it ensures minimal interference and maximum stability during instrumental analysis. The Specpure® grade guarantees ultra-low impurity levels (<10 ppb for most contaminants), making it ideal for high-sensitivity techniques like ICP-OES, ICP-MS, and atomic absorption spectroscopy (AAS). Each batch undergoes rigorous quality control with certified traceability to NIST standards, providing reliable calibration curves and quantitative accuracy. The solution’s homogeneous composition eliminates precipitation risks, while its extended shelf life (when stored properly) reduces frequent recalibration needs. Compatible with most plasma spectrometry systems, this standard minimizes matrix effects and background noise, enabling precise detection of gadolinium in complex samples. Its sealed packaging prevents contamination, and the clear labeling includes lot-specific certificates for full transparency. Whether for routine lab work or research-grade analysis, this standard ensures reproducible results without signal drift or baseline instability.
FAQs
1. What is the matrix composition of this Gadolinium standard solution?
The solution is prepared in a dilute nitric acid matrix (typically 2-5% v/v), which enhances stability and compatibility with plasma-based instruments while preventing hydrolysis or precipitation of gadolinium ions.
2. Can this standard be used for ICP-MS analysis without further dilution?
For most ICP-MS applications, further dilution is recommended to avoid detector saturation, as the 10,000µg/ml concentration exceeds typical ICP-MS working ranges. A 1:100 or 1:1,000 dilution is commonly used depending on the instrument’s linear dynamic range.
3. How does the Specpure® grade differ from analytical reagent (AR) grade standards?
Specpure® standards undergo additional purification steps to achieve impurity levels below 10 ppb for most elements, whereas AR grade may contain impurities up to 100 ppb. This makes Specpure® more suitable for ultra-trace analysis where background interference must be minimized.
4. What is the recommended storage temperature and shelf life?
Store the unopened solution at 15–25°C in its original container, away from direct sunlight. Under these conditions, the shelf life is 24 months from the date of manufacture. Once opened, use within 6 months or as validated by your lab’s stability studies.
5. Are there alternatives to nitric acid-based Gadolinium standards for specific applications?
For applications sensitive to nitric acid (e.g., certain organic matrices), hydrochloric acid-based or ammonium hydroxide-stabilized Gadolinium standards are available, though they may require compatibility testing with your instrument’s plasma conditions.
