Product Overview
This citrate ion chromatography standard (1000 mg/L in water) is formulated for high-precision analytical applications, ensuring reliable calibration and quantification in chromatographic workflows. The aqueous solution is prepared using ultra-pure citrate and deionized water, minimizing matrix interferences for accurate baseline stability. Its analytical-grade purity guarantees consistent performance across repeated injections, reducing variability in retention times and peak areas. The standard is traceable to NIST or equivalent reference materials, meeting ISO 17025 guidelines for quality assurance. Packaged in a 100 ml amber glass bottle with a tamper-evident seal, it prevents degradation from light exposure and contamination. The solution’s pH is optimized for compatibility with common anion-exchange columns, eliminating the need for additional pH adjustments. Its long shelf life (12+ months when stored at 2–8°C) ensures cost-effective usage without frequent replacements. Ideal for laboratories requiring stringent quality control, this standard supports method validation, system suitability testing, and routine analysis in environmental, pharmaceutical, or food testing protocols.
FAQs
1. What is the exact concentration of citrate in this standard?
The standard contains 1000 mg/L (1 g/L) of citrate dissolved in deionized water, verified via gravimetric preparation and certified analysis.
2. Can this standard be used with suppressed conductivity detectors?
Yes, the solution is compatible with suppressed conductivity detection systems, as it contains no interfering ions that could affect baseline stability.
3. Are there any preservatives added to extend shelf life?
No preservatives are added. The standard relies on high-purity water and sterile packaging to maintain stability under recommended storage conditions.
4. How should I handle the bottle to avoid contamination?
Use a clean, dedicated pipette or syringe to withdraw the solution. Avoid touching the bottle’s inner neck or cap to prevent microbial or particulate contamination.
5. What documentation is provided with the standard?
Each bottle includes a Certificate of Analysis (CoA) detailing the exact concentration, traceability, expiry date, and storage instructions.
