Not content with inventing the practice and theory of liquid—liquid partition chromatography, Martin (in collaboration with A.T. James) went on to invent gas-liquid chromatography (James 1952), now referred to as simply gas ehromatography. These remarkable accomplishments of Martin s appear to have been achieved with the aid of a dry sense of humor, as related later (James 1979)  

A mathematical derivation of the Plate Theory expression for Rd(V) is given in Appendix 3.1 (the equation numbers in the Appendix are in sequence with those in the main text). The final result of this derivation is  

Mobile phase Volume Concentration -A C in(p-1) Mobile phase Volume v, Concentration -A C m(p) Mobile phase Volume v, Concentration -A rn(p+1) 

Stationary phase Stationary phase stationary phase
