Product Overview

This Specpure® Zinc-68 (68Zn) plasma standard solution delivers ultra-high purity with a certified concentration of 10µg/ml in a stabilized nitric acid matrix, ensuring long-term stability and minimal matrix interference. The isotopically enriched 68Zn standard is traceable to NIST reference materials, providing reliable accuracy for trace metal quantification in complex samples. The solution is prepared using sub-boiled acids and Class 100 cleanroom conditions to eliminate contamination risks, making it ideal for demanding applications where background interference must be minimized. Its homogeneous composition ensures consistent performance across multiple analytical techniques, including ICP-MS and atomic absorption spectroscopy (AAS). The low detection limits and high signal-to-noise ratio enable precise calibration curves, even for ultra-trace analysis. Packaged in high-density polyethylene (HDPE) bottles with tamper-evident seals, the solution maintains integrity during storage and transport. Each batch undergoes rigorous multi-element analysis to confirm purity and concentration, with certificates of analysis provided for full transparency. The nitric acid matrix (2-5% v/v) ensures complete solubility while preventing precipitation or adsorption losses, guaranteeing reproducible results across different instrumental setups.

FAQs

1. What is the shelf life of this 68Zn plasma standard solution?

The solution remains stable for 24 months from the date of manufacture when stored unopened at 15-25°C. Once opened, use within 6 months for optimal accuracy.

2. Is this standard compatible with organic solvent-based sample preparation?

The nitric acid matrix is miscible with most organic solvents like methanol or acetone, but dilution may be required to prevent matrix effects in certain analytical techniques.

3. What alternatives exist for lower concentration 68Zn standards?

Dilution series can be prepared from this 10µg/ml stock using ultra-pure diluents, or custom lower-concentration standards may be available upon request.

4. How should this standard be stored to maintain accuracy?

Store upright in the original container at room temperature (15-25°C), away from direct sunlight and sources of contamination like volatile organic compounds.

5. What certification documentation accompanies this product?

Each bottle includes a certificate of analysis detailing concentration, uncertainty, traceability, and multi-element impurity screening results for quality assurance.
