Advantages of Photochemical Derivatization

1. Easy Installation, High Sensitivity

   The WelView Photochemical Reactor is positioned between the chromatographic column and the detector, enabling continuous post-column photochemical derivatization. It offers convenient installation without the need for specialized tools. The complete set of equipment includes the main unit, power cable, a pair of Peek connectors, and one straight-through connector.

2. Simple Experimental Operation, Easy Control

   The addition of photons as derivatizing agents is determined by the switch of the UV light source. In comparison to chemical derivatization, there is no need to prepare or store chemical reagents. Issues such as reagent degradation, expiration dates, and disposal are not a concern. Simply powering on is sufficient, making the operation remarkably straightforward.

3. Safe Operation, Cost Reduction

   Some chemical reagents can be toxic, whereas photochemical derivatization only requires control of the light source switch, eliminating the need to handle hazardous reagents. Additionally, there is no requirement for additional pumps, reactors, heaters, etc., significantly reducing potential factors that may interfere with the analysis.

4. LCD Display Screen for Clear Maintenance Information

   The inclusion of an LCD display screen ensures that maintenance information is easily accessible and clear.
   The user-friendly interactive interface, fault information, maintenance details, screen status colors, and status indicator lights are all designed to align seamlessly with the usage habits of your liquid chromatograph and workstation.

5. Audible Alarm for Enhanced Prompting
   In addition, we've incorporated an audible alarm! Recognizing that you might be busy and may not always notice screen anomalies, the addition of sound prompts provides an extra level of consideration. Our development engineers are certainly considerate individuals!

6. Optimized Derivatization Tube for Visible Derivatization Effects
   Furthermore, our derivatization tube utilizes FEP material with a narrower inner diameter and longer tubing, ensuring excellent transparency while achieving superior peak shapes, effectively avoiding peak broadening.

7. Dual Lamp Design for Extended UV Lamp Lifespan, Cost-Effective Consumable Usage
   The WelView Photochemical Reactor adopts a dual lamp design for improved derivatization effects, and the lamps boast an exceptionally long lifespan—up to 9000 hours! This design ensures more economical consumable usage.
