Product Overview
This Specpure® Ruthenium plasma standard solution delivers exceptional purity and stability for demanding trace metal analysis applications. Formulated at a concentration of 10,000µg/ml in a high-purity nitric acid matrix, it provides a reliable reference for instrumental techniques requiring ultra-low detection limits. The solution is manufactured under stringent ISO 9001:2015 quality controls, ensuring batch-to-batch consistency with certified values traceable to NIST standards. Its ultra-low background impurity profile (≤10 ppb for most common interferents) makes it particularly suitable for analyzing complex matrices where ruthenium appears at trace levels, such as in platinum group metal ores, catalytic converters, or environmental samples. The solution comes in amber glass bottles with PTFE-lined caps to prevent contamination and photodegradation, maintaining stability for at least 24 months when stored properly. Each batch undergoes multi-point calibration verification using primary ruthenium standards to guarantee accuracy within ±0.5% of the stated concentration. The nitric acid matrix (2-5% v/v) ensures complete ruthenium solubility while being compatible with most ICP and AAS instrument configurations without requiring additional sample preparation steps.
FAQs
1. What is the shelf life of this ruthenium standard solution when unopened?
The unopened solution maintains its certified concentration for 24 months from the date of manufacture when stored at 15-25°C in its original packaging, protected from light exposure.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the solution is specifically designed for compatibility with both ICP-OES and ICP-MS systems, though you may need to dilute it appropriately for ICP-MS applications where lower detection limits are required.
3. What materials are used for the bottle and cap to prevent contamination?
The solution is packaged in Type I borosilicate amber glass bottles with PTFE-lined polypropylene caps to minimize leaching and contamination from container materials.
4. Is this standard traceable to international reference materials?
Each batch is traceable to NIST SRM standards through an unbroken chain of comparisons, with certification documentation provided with every shipment.
5. What dilution factors are recommended for preparing working standards?
For most applications, we recommend preparing working standards by serial dilution using 2% nitric acid as the diluent, with typical dilution factors ranging from 1:10 to 1:1000 depending on your instrument’s sensitivity requirements.
