Surface potential measuring device

non-contact

Get an in-depth view of the Langmuir monolayer interactions with our KSV NIMA Surface Potential Sensor (SPOT). Overview What you can do Determine molecular orientation. The SPOT provides information about molecular orientation by observing changes in surface potential and combining the data with surface pressure information. In-depth view of Langmuir layer interactions. Surface pressure isotherm alone is unable to separate the reasons for surface pressure changes. Combined with the SPOT, the data gathered from the layer is doubled, giving an in-depth understanding of the layer. Determine effective dipole moments. The sensor can be used to determine effective dipole moments through simple surface potential measurements of a compressed film. Characterize film electronic structure. Small changes in the electronic structure of molecules can be detected by measuring the change in surface potential. Characterize molecular structure. Quantify the effects of changes to molecular structure through positional offsets and peak values of the surface potential plots. Monitor complex formation. Observe and follow complex formations between monolayers, sub-phase species or adsorbates. 3 reasons to invest Double the data Surface Potential Sensor is operated with KSV NIMA LB Software and does not require any additional software. Both the surface pressure and surface potential are automatically plotted in the same graph for simple comparison. Double the amount of data – all in one software. Accurate and reproducible measurements The non-contact and non-destructive vibrating plate capacitor method ensures excellent accuracy and reproducibility.
