Product Overview
This Hafnium 1000 ppm ICP-ML single-element standard represents the gold standard for trace metal quantification in advanced analytical laboratories. Formulated in a 2% nitric acid matrix, this liquid standard ensures exceptional stability and minimal matrix interference during ICP-OES or ICP-MS analysis. The 1000 ppm concentration provides optimal sensitivity while maintaining linear calibration ranges, making it particularly valuable for analyzing complex samples where Hafnium appears at trace levels. Each batch undergoes rigorous quality control with NIST-traceable certification to guarantee ±1% concentration accuracy. The solution’s ultra-low impurity profile (with all contaminants <10 ppb) eliminates spectral overlaps that could compromise analytical precision. Packaged in HDPE bottles with tamper-evident seals, the standard maintains its integrity during storage and transport. The acidified matrix prevents precipitation while ensuring complete element solubility across a wide pH range. This standard's extended shelf life (24 months unopened) and lot-specific certificate of analysis make it a reliable reference material for laboratories requiring reproducible Hafnium measurements in environmental, geological, or industrial samples.
FAQs
1. What matrix acid is used in this Hafnium standard and why?
The standard uses 2% nitric acid as the matrix, which provides optimal stability for Hafnium while preventing hydrolysis or precipitation. Nitric acid also minimizes spectral interferences during ICP analysis.
2. How should this standard be stored to maintain its certified concentration?
Store unopened at 15-25°C in the original container. After opening, keep tightly sealed and protected from light. The standard remains stable for 12 months after first opening when stored properly.
3. Is this standard compatible with both ICP-OES and ICP-MS instruments?
Yes, the 1000 ppm concentration and nitric acid matrix make it suitable for both ICP-OES and ICP-MS applications, though you may need to dilute it further for ICP-MS to avoid detector saturation.
4. What certification documentation comes with this standard?
Each bottle includes a lot-specific certificate of analysis with NIST-traceable concentration values, expiration date, and complete impurity profile showing all elemental contaminants below 10 ppb.
5. Can this standard be used for preparing multi-element calibration solutions?
While designed as a single-element standard, it can be combined with other compatible single-element standards to create custom multi-element calibration solutions, provided the matrix acids are compatible.
