Overview
The Window Maker™ is designed to create detection windows in fused silica capillaries used for capillary electrophoresis (CE) applications. The device uses a controlled heating element that removes the thin polyimide coating from the capillary, exposing the fused silica for optical detection.
The amount of heat produced is specifically engineered to perform this task quickly and consistently without damaging the capillary itself.
Heating Characteristics
The exact amount of heat generated by the Window Maker® coils has not been formally quantified.
However, the heating system is designed to:
- Rapidly remove the polyimide coating
- Expose a clean detection window
- Preserve fused silica capillary integrity
- Produce consistent capillary windows
- Minimize the risk of capillary damage
The heating profile has been optimized for capillary preparation rather than for producing a specific measured temperature.
Effect on Fused Silica Capillaries
The Window Maker™ is intended to remove only the external polyimide layer applied to the capillary.
When used properly:
- The polyimide coating is removed efficiently.
- The fused silica capillary remains intact.
- Optical detection windows can be created quickly.
- Capillary performance is maintained.
This controlled heating process helps ensure reliable preparation of CE capillaries for analytical use.
