Hi Stefan, Thank you for your response. I do not get a false engage. The unsucessful engage means that the scanning window do not appear. It just keep engaging for quite a long time. Sometimes the tip does not move downwards after hitting the engage button. I doubt that it may be caused by the too low P and I value. Although the cantilever tune exhibit

Hi, I have some difficulty in engaging the SNL probe in liquid on Innova. I perform the experiment in liquid, the substrate is mica. I tried contact and tapping mode, neither could engage successfully. However, the NPG probe can be engaged easily. The parameters are: Cantilever-C, resonace frequency ~15kHz, targeting free amplitude 3V, 20×gain

Hi, Can single point spectroscopy be performed in Tapping Mode using Innova SPM? If I want to know the tapping amplitude in nanometers, should I use the method of taking a force curve in Tapping Mode which produces an amplitude vs Z curve (mentioned in earlier post) or Thermal Tune? Thanks a lot! Zhuoyang

Hi, In Innova User Manual I read this sentence: "The low gain settings should be used for atomic scale imaging with the large area scanner." My question is whether the low gain settings could be used with the small area scanner? Thank you! Zhuoyang

Could you please tell me the coolilng sample stages available? I may need that when summer comes. I am using Innova. Thank you!

Hi, Our lab has recently got an Innova AFM. My question is that dose it have the capability to scan membrane proteins? I have been working on it for the past two months and found that the instrument is unstable and the results not reproducible. I haven't been successful in scanning nanoscale molecules. Moreover, I haven't seen any published
