Product Overview
This oxalate ion chromatography standard delivers a precise 1000 mg/L concentration in a stable aqueous solution, engineered for high-accuracy analytical applications. Formulated under stringent quality controls, it ensures minimal matrix interference and consistent performance across chromatographic systems. The standard is prepared using ultra-pure reagents and deionized water, eliminating contaminants that could skew results. Its extended shelf life and traceable certification make it ideal for laboratories requiring reproducible data in environmental, industrial, or research settings. The solution is compatible with most IC columns and detectors, reducing the need for frequent recalibration. Each batch undergoes rigorous testing for concentration verification, pH stability, and microbial contamination, guaranteeing reliability from the first to the last drop. The 100 ml pack size balances cost-efficiency with practical usage volumes, minimizing waste while providing sufficient quantity for repeated testing cycles.
FAQs
1. What is the exact shelf life of this oxalate standard when stored properly?
When stored unopened at 2-8°C and protected from light, this standard maintains its certified concentration for 24 months from the date of manufacture. Always check the label for batch-specific expiry details.
2. Can this standard be used with suppressed conductivity detectors?
Yes, the solution is fully compatible with suppressed conductivity detection systems commonly used in ion chromatography. Its low background conductivity ensures minimal baseline noise during analysis.
3. Are there any known matrix interferences with this oxalate standard?
The standard is prepared in ultra-pure water with no added preservatives, significantly reducing potential interferences. However, always verify compatibility with your specific sample matrix through preliminary testing.
4. What’s the recommended procedure for handling this standard to prevent contamination?
Use dedicated, clean pipettes or syringes for each aliquot to avoid cross-contamination. Work in a laminar flow hood if available, and never return unused portions to the original bottle. Always wear appropriate PPE when handling.
5. How does this compare to oxalate standards prepared in organic solvents?
This aqueous-based standard offers better stability for most IC applications compared to organic solvent-based alternatives, which may introduce additional peaks or require special column conditions. It’s optimized for direct injection without solvent exchange.
