Product Overview
This Holmium 10 ppm ICP-ML single-element standard is engineered for high-precision trace metal analysis, offering exceptional purity and consistency for spectroscopic applications. Formulated under stringent quality controls, this liquid standard ensures minimal matrix interference, making it ideal for inductively coupled plasma-mass spectrometry (ICP-MS) and other advanced analytical techniques. The 10 ppm concentration provides optimal sensitivity for calibration curves, reducing dilution errors while maintaining linear response across detection ranges. Its stable chemical composition minimizes degradation over time, ensuring long-term reliability in laboratory settings. The solution is prepared in a high-purity acid matrix to prevent contamination and preserve elemental integrity. Whether used for routine quality control or research-grade analysis, this standard delivers reproducible results with low detection limits. The 100 ml pack size offers an economical balance between sufficient volume for repeated use and minimal waste. All batches undergo rigorous testing to verify concentration accuracy and absence of interfering elements, meeting international analytical standards.
FAQs
1. What is the shelf life of this Holmium ICP standard when stored properly?
When stored unopened in its original container at controlled room temperature (15-25°C), this standard maintains its specified concentration for at least 24 months from the date of manufacture. Always check the expiration date on the label for precise guidance.
2. Can this standard be used with ICP-OES instruments, or is it specifically for ICP-MS?
While optimized for ICP-MS applications due to its ultra-low detection limits, this 10 ppm Holmium standard can also be used with ICP-OES instruments. You may need to adjust dilution factors based on your instrument’s sensitivity requirements and the specific emission lines being monitored.
3. What acid matrix is used in this Holmium standard solution?
The solution is prepared in a high-purity nitric acid matrix, typically at 2-5% concentration. This matrix is chosen for its compatibility with most ICP systems and its ability to stabilize the Holmium ions while minimizing spectral interferences from the acid itself.
4. How should I handle potential contamination when working with this standard?
Use dedicated, acid-washed class A volumetric pipettes and containers to prevent cross-contamination. Always wear appropriate PPE including nitrile gloves and safety goggles. Work in a clean, dust-free environment, preferably under a laminar flow hood if available, to maintain the standard’s integrity.
5. What certification or documentation comes with this Holmium standard?
Each batch includes a Certificate of Analysis (CoA) detailing the exact concentration, lot number, expiration date, and traceability information. The CoA also provides data on tested impurities and the analytical methods used for verification, ensuring compliance with international quality standards.
