Product Overview
This Specpure® potassium plasma standard solution delivers exceptional purity and accuracy for demanding analytical applications. Formulated at a precise 1000µg/ml concentration, it serves as a reliable calibration standard for inductively coupled plasma optical emission spectrometry (ICP-OES) and atomic absorption spectroscopy (AAS). The solution is prepared using ultra-high-purity potassium compounds dissolved in a stabilized matrix to prevent precipitation and ensure long-term stability. Its low background interference makes it particularly suitable for trace metal analysis where sensitivity is critical. The Specpure® grade guarantees minimal impurities, with each batch rigorously tested for consistency and certified for analytical use. The aqueous formulation eliminates the need for additional dissolution steps, saving time in sample preparation. Packaged in high-density polyethylene bottles to prevent contamination, this solution maintains its integrity throughout its shelf life. Whether used for routine calibration or complex research applications, this potassium standard provides the reproducibility and accuracy required for reliable analytical results.
FAQs
1. What is the shelf life of this potassium plasma standard solution?
When stored unopened at room temperature, this solution maintains its certified concentration for 24 months from the date of manufacture. Once opened, it should be used within 6 months for optimal accuracy.
2. Can this solution be used for flame photometry applications?
While primarily designed for ICP-OES and AAS, the solution’s high purity makes it compatible with flame photometry when properly diluted to match the instrument’s working range.
3. What material are the bottles made from?
The solution is packaged in high-density polyethylene (HDPE) bottles that are resistant to chemical leaching and contamination, ensuring sample integrity.
4. Is this solution traceable to NIST standards?
Yes, each batch is manufactured with reference materials traceable to NIST standards, with certification documentation provided for quality assurance.
5. How should I handle potential contamination during use?
Always use clean, dedicated pipettes and avoid touching the bottle opening. Store the bottle tightly sealed when not in use to prevent atmospheric contamination.
