Product Overview
1,2-Dichloroethane (99.8% purity) is a high-performance HPLC-grade solvent engineered for demanding laboratory applications where precision and consistency are critical. This ultra-pure variant undergoes rigorous purification to eliminate trace impurities, ensuring minimal UV absorbance and exceptional baseline stability in chromatographic analyses. Its low water content (<0.01%) and controlled acidity/alkalinity make it particularly suitable for sensitive detectors like UV-Vis and mass spectrometry. The solvent’s high volatility (boiling point: 83.5°C) enables rapid evaporation during sample preparation, while its excellent miscibility with organic solvents enhances versatility in multi-solvent systems. Packaged in amber glass bottles to prevent photodegradation, this reagent maintains stability during storage and transport. The 99.8% assay guarantee, verified via GC analysis, ensures reproducible results across batch-to-batch applications. Its non-hygroscopic nature further simplifies handling in humid laboratory environments, reducing the risk of moisture-induced contamination.
FAQs
1. What is the maximum allowable water content in this HPLC-grade 1,2-dichloroethane?
The water content is strictly controlled to below 0.01% (100 ppm), as verified by Karl Fischer titration, ensuring compatibility with moisture-sensitive applications.
2. Can this solvent be used with reverse-phase HPLC columns?
Yes, its low UV cutoff (225 nm) and minimal residual impurities make it suitable for reverse-phase HPLC, including C18 and phenyl-hexyl stationary phases.
3. How does the purity compare to ACS-grade 1,2-dichloroethane?
HPLC-grade exceeds ACS specifications, particularly in UV transparency and trace metal content, with iron, lead, and heavy metals each below 0.1 ppm.
4. What precautions are needed for long-term storage?
Store tightly sealed in the original amber bottle at 15–25°C, away from direct sunlight and ignition sources. Use within 12 months of opening for optimal performance.
5. Is this solvent compatible with PTFE or glass syringes?
It is fully compatible with both PTFE and borosilicate glass, though prolonged contact with some plastics (e.g., polyethylene) may cause swelling.
