Method of impregnating a carrier a matrix with solid and/or liquid compounds using compressed gases, and materials thus impregnated

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...

Zusammenfassung:	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.
