Product Overview
This Rubidium plasma standard solution (10,000µg/ml) is formulated with Specpure® grade purity, ensuring minimal matrix interference and exceptional accuracy in spectroscopic applications. The solution is stabilized in a high-purity acid matrix, making it ideal for calibration curves, method validation, and trace-level determinations in complex samples. Its ultra-low impurity profile guarantees reliable results across ICP-OES, AAS, and other high-sensitivity techniques. The solution is packaged in amber glass bottles to prevent photodegradation, with tamper-evident seals for integrity. Each batch undergoes rigorous multi-element analysis to confirm concentration accuracy and absence of contaminants. The high concentration (10,000µg/ml) allows for flexible dilution while maintaining precision, reducing preparation time for routine and research-grade analyses. Compatible with most standard labware, this solution eliminates the need for in-house standard preparation, saving time and reducing human error in critical workflows.
FAQs
1. What is the shelf life of this Rubidium 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 performance.
2. Can this standard be used for ICP-MS applications?
While primarily designed for ICP-OES and AAS, it can be used for ICP-MS after appropriate dilution to avoid detector saturation from the high concentration.
3. What diluent is recommended for preparing lower concentration standards?
Use 2% nitric acid (AR grade) or deionized water (18.2 MΩ·cm) as the diluent, depending on your instrument’s requirements and sample matrix.
4. How does the Specpure® grade differ from standard analytical grades?
Specpure® undergoes additional purification steps to remove trace metallic and anionic contaminants, resulting in lower detection limits and reduced background interference.
5. Are the bottles provided with safety seals?
Yes, each bottle features a tamper-evident PTFE-lined cap and an outer security seal to prevent contamination during storage and transport.
