Technology Overview
The technology outlines a process for forming frits within capillaries, crucial for retaining packing material in chromatography columns. It employs a laser sintering technique that carefully shapes a laser beam to sinter particles without damaging the capillary's polymer coating. This method is compatible with high-pressure liquid chromatography (HPLC) applications, ensuring minimal pressure drop and preventing reactivity with analytes.
Key Advantages
- Enables precise location and length control of frits within capillaries
- Maintains capillary integrity by avoiding damage to the polymer coating
- Ensures high durability and resistance to high-pressure liquid flows
- Minimizes pressure drops and prevents analyte reactivity and void formation
Problems Addressed
- Damage to capillary coatings during frit formation
- Limitations in frit location and length control
- High pressure drops and reactivity with analytes
- Void formation affecting column integrity
Market Applications
