In System Modeler 14.0 the default version of Modelica Standard Library (MSL) was changed to 4.0.0. The current release of Aircraft library requires MSL 3.2.3, so you need to change the MSL version (right click on Modelica in the class browser and select Version > 3.2.3.
The IndustryExamples.LifeSciences.Chromatography.ChromatographySeparation example requires the BioChem library (as stated in the documentation when you open it), you can get it here https://www.wolfram.com/system-modeler/libraries/biochem/.
