X-ray Diffraction Tubes
SEIFERT Analytical X-ray
SEIFERT Analytical X-ray oers 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 uorescence 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 dierent spot
sizes are available.
A Broad focus tube is preferred if intensity is the only
major requirement. However, in most powder diractom-
etry applications both high diraction 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.
