Digital interface for remote control of a Cary 14 spectrophotometer

Abstract

A general purpose interface has been employed to digitize data from a Cary 14 spectrophotometer, transmit data to a PDP-l1/20 laboratory computer, and operate the spectrophotometer remotely under program control. A powered bidirectional bus approximately 50 m in length connects the two instruments for communication of data and commands,

“…In the case of heavy toxic metals such as lead and cadmium, the mineralization remains the limiting step, whatever the method of measurement used. Although there exist many different procedures, dry ashing seems best suited to this type of problem, as it is safer and can be run automatically (7,2). Also, smaller quantities of reagents are needed which reduces the possibility of extraneous pollution.…”
