Sorting apparatus including a chute, on which objects are moved in succession by gravitational force, the chute having a cutout with a measuring region. An LIBS laser device is arranged adjacent to the cutout to carry out spectroscopic measurement on the moving objects. A separating device separates out certain objects, and a control device controls and/or adjusts the separating device as a function of the measurement results of the LIBS laser device. The chute includes at least a first portion, through which the objects can be moved first and centered normal to the conveying direction by gravitational force, and a second portion that is flat. The cutout includes the measuring region is arranged in the second portion.
