Abstract

In most modern analytical laboratories, the number of samples being examined by physical methods has increased several hundred per cent in the last few years. This increase has frequently been disproportionate to both the number of instruments and the available operating personnel. Because of its wide usefulness, the infrared technique, in particular, has had difficulty in keeping up with the ever-increasing sample load. In fact, some groups have become more or less selective in accepting samples. This is true in our laboratory and has forced us to consider ways of minimizing both spectrophotometer time per sample and the amount of operator attention required to run the spectrophotometer. The latter saving would permit the operator to give more time to calculations, preparation of next sample, etc.
