New analytical systems are assumed to be very user-friendly and "calibration-free". What are your experiences? Is there any relationship to the effective size of the EDS detector?
Known are the length in a triangle ABC of a tetrahedron ABCD, i.e., also all angles between A, B and C are known. The position of D is, however, unknown, but the angles between all edges to D,...
