AB  - We report on the application of a two-dimensional position-sensitive area 
      detector towards grazing emission x-ray fluorescence (GEXRF) spectroscopy. GEXRF 
      allows for surface-sensitive studies with nanometer-scale accuracy in the depth 
      direction by measuring the intensity variation of an x-ray fluorescence line with 
      the grazing emission angle. The presented experimental setup is based on a fixed 
      sample-detector arrangement and does not require any moving components. We show 
      that the dispersion of the grazing emission angle along a position-sensitive 
      detector allows to acquire with an excellent angular resolution a full GEXRF 
      profile in a single measurement. Moreover, the use of a two-dimensional detector 
      allows to perform experiments with an increased solid angle of detection per 
      emission angle. This results in combination with the nonsequential and 
      simultaneous acquisition of the GEXRF profiles of different emission lines in 
      considerably reduced acquisition times. The realization, the demands, and the 
      main characteristics of the scanning-free GEXRF setup will be presented. A few 
      experimental examples will serve to illustrate the analytical possibilities 
      offered by the presented setup.
