Summary
A computer program has been developed for calculating the linear retention index even when some of the reference compounds are missing or the substance appears outside the range of the reference compounds. The Kovats' index is also calculated and the requirement that the gas holdup time has to be measured has been overcome by using the computer to fit the data to a straight line. The program, written in FORTRAN, has been developed for an interactive system but could readily be adapted to any system.
