Automation of simple instrumentation for Langmuir-Blodgett technology

Abstract

Simple and sensitive electronic circuitry suitable for automated monolayer analysis and constant pressure deposition at an air-water interface is described. The performance criteria are considered with respect to instrumental response and the resolution of chemical effects observed during the acquisition of pressure-area isotherms. The advantages of the circuitry, the Wilhelmy plate pressure transducer and the cost are compared with a popular commercial trough system.
