About This Product
■Automatic measurement of adsorption isotherm
The E series water vapor adsorption measuring device continuously changes the relative humidity from 0%RH to 95%RH, measures the weight change due to water vapor sorption/desorption of the sample with extremely high accuracy, and automates the adsorption isotherm measurement. When evaluating the water adsorption process of a material, the water vapor adsorption isotherm, that is, the relationship between the material's equilibrium water content and relative humidity, is important and must be measured. Until recently, adsorption isotherms were determined by keeping the temperature in a desiccator constant, waiting for equilibrium, then taking out the sample and measuring its weight, but this method was very time consuming.
■Applications
・Measurement of the effect of water vapor on pharmaceutical raw materials
・Measurement of reversible and irreversible effects of water vapor on stable formulations
・Obtaining the adsorption isotherm from the water vapor adsorption equilibrium at the humidity stage
・Measurement of heterogeneity in sample batches
・Measurement of water vapor mobility by velocity determination
・Strength of bond between water vapor on the surface or in the bulk and the raw material
・Amorphous transition measurement
・Measurement of hydration and solvate formation points
・Measurement of dryness
・Measurement of diffusivity and activation energy
・Measurement of water vapor adsorption content
■Features
・Raman spectroscopic probe and FTIR probe can be connected
・Equipped with a microscope camera as standard. Sample operation is easy with the top balance system.
