Product Overview
This nitric acid calibration blank represents a single-element standard specifically formulated for inductively coupled plasma (ICP) spectroscopy applications. Prepared from ultra-high-purity nitric acid (≤0.01% trace metal impurities), it serves as a critical reference material for establishing baseline measurements and correcting matrix effects in elemental analysis. The solution undergoes rigorous quality control to ensure consistency across batches, with certified traceability to NIST standards where applicable. Its low particulate content (<0.2 µm filtered) and stable pH (1.0-1.5) make it particularly suitable for sensitive ICP-MS and ICP-OES instruments requiring minimal background interference. The blank's composition mirrors typical sample matrices while remaining free of target analytes, enabling accurate subtraction of instrumental noise and reagent contributions. Packaged in HDPE bottles with tamper-evident seals, the solution maintains its integrity during storage and handling. Each unit includes a detailed certificate of analysis documenting impurity profiles and recommended usage parameters for optimal calibration performance.
FAQs
1. What is the typical shelf life of this nitric acid blank standard?
The unopened standard remains stable for 24 months from the date of manufacture when stored at 15-25°C. Once opened, use within 3 months for optimal accuracy.
2. Can this blank be used for both ICP-OES and ICP-MS applications?
Yes, the ultra-low impurity profile makes it suitable for both techniques, though you may need to adjust dilution factors based on your instrument’s sensitivity requirements.
3. What materials are used in the bottle and cap construction?
The solution comes in HDPE bottles with LDPE caps, both tested for trace metal leaching to ensure no contamination of the blank standard.
4. How does this blank differ from regular nitric acid?
Unlike reagent-grade nitric acid, this blank undergoes additional purification to remove trace metals and organic contaminants, with certified impurity levels below 10 ppb for most elements.
5. What documentation is provided with each batch?
Every unit includes a certificate of analysis detailing impurity concentrations, batch number, expiration date, and recommended storage conditions for quality assurance.
