The invention relates to a method for impregnating a support matrix with
solid and/or liquid compounds using a compressed gas or a compressed
mixture of gases at densities ranging from 0.15 to 1.3 kg/l and at least
two unsymmetrical pressure changes (pulsations). The method is further
characterized in that both a multitude of impregnating substances such as
biologically active compounds, technical materials or metal-organic
compounds, as well as support matrices of biological origin and organic
or inorganic substances can be used that have large inner surfaces and/or
inner surfaces that are difficult to access.
