Product Overview
This methane sulfonate ion chromatography standard is a high-purity, aqueous solution formulated at a precise concentration of 1000 mg/L, designed to deliver reliable and reproducible results in ion chromatography (IC) applications. The solution is prepared using ultra-pure water and analytical-grade methane sulfonate, ensuring minimal interference from contaminants and consistent performance across multiple runs. Its stability under standard lab conditions makes it ideal for calibration curves, system suitability testing, and routine quantitative analysis where accuracy is critical. The solution is provided in a sealed, amber glass bottle to prevent degradation from light exposure, with a tamper-evident cap to guarantee integrity upon delivery. Each batch undergoes rigorous quality control, including traceability to NIST or equivalent reference materials, to meet the stringent demands of modern analytical laboratories. The absence of preservatives or additives ensures compatibility with a wide range of IC columns and detectors, including conductivity and UV-Vis systems. Whether used for environmental testing, pharmaceutical analysis, or industrial process monitoring, this standard eliminates the need for in-house preparation, reducing variability and saving valuable lab time.
FAQs
1. What is the shelf life of this methane sulfonate standard under unopened conditions?
The standard remains stable for 24 months from the date of manufacture when stored unopened at room temperature (15–25°C) in its original packaging. Avoid exposure to direct sunlight or extreme temperatures to preserve integrity.
2. Can this solution be diluted for lower concentration requirements?
Yes, the 1000 mg/L concentration allows for precise serial dilution using deionized water or a compatible solvent. Ensure the diluent is free of ionic contaminants to maintain accuracy in downstream applications.
3. Is this standard compatible with suppressed conductivity detection in IC?
The solution is fully compatible with suppressed conductivity detectors, as it contains no interfering anions or cations that could compromise baseline stability or peak resolution during analysis.
4. How should the bottle be handled to prevent contamination?
Use clean, dedicated pipette tips or syringes for sampling to avoid cross-contamination. Always reseal the bottle tightly after use and store it upright to prevent leakage or cap thread corrosion.
5. Does this standard require refrigeration after opening?
While refrigeration (2–8°C) can extend stability post-opening, it is not mandatory if the solution is used within 3 months. For long-term storage after opening, aliquot into smaller, airtight containers to minimize exposure to oxygen and humidity.
