X-ray Diffraction Tubes

SEIFERT Analytical X-ray

SEIFERT Analytical X-ray offers a wide array of X-ray

Tube types and anode materials to deliver the appropri-

ate wavelength (λ) and match a variety of user applica-

tion requirements.

The choice of anode material can be determined by the

desired wavelength and fluorescence radiation of the

components under investigation (Table 3). Appropriate

Filters, necessary to cut out K-beta radiation, are listed in

Table 2.

SEIFERT Analytical X-ray tubes are available with Fine,

Long Fine, Normal or Broad Spot focus. Micro focus is

available upon request.

Tubes have four Beryllium windows with a diameter of

14 mm and a thickness of just 300 µm.

Two windows deliver point focus and two deliver line fo-

cus for maximum versatility (Fig. 1). Five different spot

sizes are available.

A Broad focus tube is preferred if intensity is the only

major requirement. However, in most powder diffractom-

etry applications both high diffraction line resolution and

high intensity are required. In this case, a Long Fine focus

tube is ideal because it combines the focal width of the

Fine focus tube with the length of the Broad focus tube.
