EKT Capillary Burner

EKT Capillary Burner

The removal of the polyimide coating in order to provide a UV transparent window is often a
source of inaccuracy in CE experiments.

For convenient and reproducible preparation of UV transparent windows in polyimide covered
capillaries, EKT have developed an easy to use capillary burner device. The capillary is
simply pushed through the guide holes until it reaches the correct position for the window
as chosen by the user and the simple push of a button initiates a controlled heating of the
capillary making a small, precise and highly reproducible window.

Capillary Burner (continued) Burner Filaments The EKT Capillary Burner is delivered fitted with a standard burner filament which produces a detection window with an approximate length of 2mm. This standard filament can be removed and replaced with a filament producing a longer or shorter window in accordance with the analyst's requirements. Burner filaments are available in three different coil lengths: 1mm, 2mm and 3mm.

The diagram below shows an example of four different windows created using the standard
2mm burner coil on a 50μm i.d. 375μm o.d. capillary. The high degree of reproducability of
windows produced using the EKT burner is clearly evident. (Test carried out by an independent
laboratory)
