Langmuir and Langmuir-Blodgett troughs and deposition troughs

WebbLangmuir troughs are used to create, modify and study monolayers at either the gas-liquid or liquid-liquid interface (Langmuir films). A Langmuir film can be defined as an … A Langmuir–Blodgett trough (LB trough) is a laboratory apparatus that is used to compress monolayers of molecules on the surface of a given subphase (usually water) and measures surface phenomena due to this compression. It can also be used to deposit single or multiple monolayers on a solid substrate.
