How to Measure pH in Small Samples
27 Feb 2017In various life sciences applications it is necessary to accurately measure the pH of very small samples, without risking introducing errors through sample manipulation or dilution. This can be difficult with standard pH sensors as the sensing glass is not exposed to enough sample. This application note describes how METTLER TOLEDO’s micro sensors and surface sensors can be used to optimize results in smaller samples, including the InLab® Micro-Pro-ISM and InLab® Surface-Pro-ISM.

pH Meters and ElectrodesIon and pH meters are electrochemical equipment used to measure the pH (acidity or alkalinity) or specific ion concentration of a solution. Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis.
