Product Overview

This Specpure® zinc plasma standard solution delivers exceptional purity and accuracy for trace metal analysis in advanced spectroscopic techniques. Formulated at a precise 1000µg/ml concentration, it serves as a reliable calibration standard for instruments requiring high-precision measurements. The solution is prepared using ultra-pure zinc in a stabilized matrix, ensuring long-term stability and minimal interference from contaminants. Its low background impurity levels make it particularly suitable for sensitive analytical methods where even trace amounts of other elements could compromise results. The aqueous formulation provides consistent performance across various detection platforms, while the Specpure® certification guarantees adherence to strict quality control protocols. Each batch undergoes rigorous testing to verify concentration accuracy and absence of interfering substances. The solution comes in amber glass bottles to protect against photodegradation, with tamper-evident seals to maintain integrity during storage and handling.

FAQs

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

The solution maintains its specified concentration for 24 months from the date of manufacture when stored unopened at 15-25°C. Once opened, we recommend using within 6 months for optimal accuracy.

2. Can this standard be used for both ICP-OES and ICP-MS applications?

Yes, the ultra-high purity and stabilized matrix make it compatible with both ICP-OES and ICP-MS instruments, though you may need to dilute it appropriately for ICP-MS to avoid detector saturation.

3. What material are the bottles made from?

The solution comes packaged in Type I borosilicate glass bottles with polypropylene caps, specifically chosen for their chemical resistance and low leachable properties.

4. Is this solution traceable to NIST or other primary standards?

The concentration is verified against certified reference materials that are traceable to NIST standards, ensuring measurement reliability for your analytical workflows.

5. What’s the typical uncertainty value for this standard?

The expanded uncertainty at 95% confidence level is typically ±1% of the stated concentration, as documented in the certificate of analysis provided with each batch.
