Product Overview
This phosphate standard solution is a meticulously prepared aqueous reference material containing a certified concentration of PO₄³⁻ ions, designed specifically for ion chromatography (IC) applications. The solution undergoes rigorous quality control to ensure traceability, stability, and accuracy, meeting the demands of precise analytical workflows. Formulated in ultra-pure water, it minimizes matrix interferences, making it ideal for calibration curves, instrument validation, and routine phosphate quantification. The standard is compatible with most IC systems and columns, including anion-exchange and suppressed conductivity setups. Its long shelf life and resistance to microbial contamination are achieved through specialized preservation techniques, ensuring consistent performance over extended storage periods. The solution’s concentration is certified via primary standards and validated using NIST-traceable protocols, providing confidence in data reproducibility. Whether used for environmental testing, research, or industrial process control, this standard delivers reliable phosphate ion detection with minimal baseline drift or peak tailing. The packaging is designed to prevent contamination, featuring tamper-evident seals and light-resistant materials to maintain integrity during transport and storage.
FAQs
1. What is the exact concentration of PO₄³⁻ in this standard solution?
The concentration is certified on the certificate of analysis (CoA) included with each batch, typically ranging between 10–1000 ppm depending on the variant. Always refer to the CoA for precise values.
2. Can this solution be used with non-suppressed ion chromatography systems?
Yes, it is compatible with both suppressed and non-suppressed IC systems. However, for non-suppressed setups, ensure your detector (e.g., conductivity or UV-Vis) is optimized for phosphate ion sensitivity.
3. How should this standard be stored to maintain stability?
Store the unopened bottle at 15–25°C in a dark, dry place. Once opened, tightly recap and refrigerate at 2–8°C. Avoid freezing, as it may alter the solution’s homogeneity.
4. Is this standard traceable to NIST or other international reference materials?
The solution is manufactured using NIST-traceable primary standards and follows ISO/IEC 17025 guidelines for calibration. The CoA provides full traceability documentation.
5. What alternatives are available if I need a different phosphate ion concentration?
Custom concentrations can be prepared upon request. For immediate needs, consider diluting this standard with ultrapure water (18.2 MΩ·cm) using volumetric glassware for lower concentrations.
