Determination of the MacMullin number

A valuable way to compare battery separators is to monitor the difference between the resistivity of the separator soaked in the electrolyte and the resistivity of the free electrolyte. The ratio of these two values is the MacMullin number. This Application Note shows how to perform the necessary measurements and...

In situ SERS effect with screen-printed silver electrodes

In this work, time resolved Raman spectroelectrochemistry measurements with screen printed electrodes are shown.  The instrument used combines in a totally integrated box: a 785 nm laser source, a high resolution Raman spectrometer and a bipotentiostat/galvanostat. Experiments are controlled with an excellent spectroelectrochemical software which allows real time data collection...

Near-infrared spectroscopy for monitoring a single-pot granulator

This Application Note shows the capability of a novel probe design equipped with a NIRS XDS Process Analyzer for predicting the residual amounts of solvent during the drying phase in a high-shear granulator. This system configuration can reduce the powder sample density variance such that moisture and solvent levels can...
