  • Page 4: Introduction

    0660881c - fastCTD Profiler 1. Introduction An evolution of the miniCTD, the fastCTD Profiler has been designed to deliver the highest quality CTD casts at fast drop rates as well as conventional casts. A conductivity cell designed for optimum flow-through, a fast response thermistor temperature sensor and a 0.01% pressure sensor synchronously sampling at up to 32Hz deliver the highest quality profiles in a lightweight and robust package.

    0660881c - fastCTD Profiler 2.4.5.1. Quenching Quenching refers to the reduction in fluorescence of a fluorophore. Several processes can result in quenching: 1. Chloride is known to quench quinine sulphate and Fluorescein. It is, therefore, advisable to prepare any fluorophore solutions with RO* or DI** water.
