If a sheet of paper or cloth contacts a container filled with water or alcohol in which a complex pigment is dissolved, capillary action will carry the mixture up the paper or cloth, but the components of the pigment will not all travel at the same rate. Temperature range -35 to +45°C Electronic Thermo Hygrograph Ask Price The monitoring of climatic conditions such as temperature, relative humidity, dewpoint and moisture in industry is often vital to the success of the application of the coating. Mass Spectrometry (MS) is an analytical chemistry technique that helps identify the amount and type of chemicals present in a sample by measuring the mass-to- charge ratio and abundance of gas-phase ions. They are as follows:1) Seebeck effect: The Seebeck effect states that when two different or unlike metals are joined together at two junctions, an electromotive force (emf) is generated at the two junctions. A rotating drum is driven by a precision electronic Quartz clock. The hairs are bundled together and stretched between a fixed pin and movable pin. Measurements are recorded onto a rotating paper chart.
