Product Overview
This Specpure® Iridium AAS standard solution delivers 1000µg/ml of ultra-pure iridium in a matrix-free aqueous formulation, engineered for superior accuracy in atomic absorption spectroscopy (AAS) and inductively coupled plasma optical emission spectrometry (ICP-OES). The solution undergoes rigorous purification to eliminate trace contaminants, ensuring reliable calibration curves and interference-free analysis. Its stable chemical composition prevents precipitation or degradation over time, maintaining consistent performance across repeated measurements. The high concentration allows for precise dilution to working standards, reducing preparation errors. Compatible with most AAS/ICP-OES instruments, this solution meets international purity standards for research-grade applications. The amber glass packaging protects against light-induced degradation, while the tamper-evident seal guarantees integrity upon delivery. Ideal for laboratories requiring trace-level iridium quantification, this standard solution eliminates the need for in-house preparation, saving time and reducing contamination risks.
FAQs
1. What is the shelf life of this Iridium AAS standard solution?
When stored unopened at 15-25°C in its original packaging, the solution maintains stability for 24 months from the date of manufacture. Always check the label for the exact expiration date.
2. Can this solution be used for ICP-MS applications?
While primarily formulated for AAS/ICP-OES, the ultra-high purity makes it suitable for ICP-MS after appropriate dilution. Verify compatibility with your specific ICP-MS instrument requirements.
3. What dilution medium is recommended for preparing working standards?
Use 2% v/v high-purity nitric acid (HNO₃) or 1% v/v hydrochloric acid (HCl) as the dilution medium to maintain stability and prevent adsorption losses.
4. How should I handle potential contamination during aliquoting?
Use Class A volumetric pipettes or micropipettes with dedicated tips for iridium solutions. Rinse with 10% HNO₃ followed by deionized water between uses to prevent cross-contamination.
5. What alternatives exist for lower concentration requirements?
For concentrations below 1000µg/ml, consider our pre-diluted iridium standards at 100µg/ml or 10µg/ml, which offer the same Specpure® purity with reduced preparation steps.
