  • Re: AFM in liquids

    Hello Stefan, I sent you the address where you can send the cantilever to. As I told, I tried working in contact mode. But for some reason I still have the same problem, that the AFM is unable to recognize the position in which it has contact to the surface. I drove it manually down and supervised the movement. At some point I could see the deflection

    Thank you very much for the information. I have to discuss now whether I can get those cantilever or not. Otherwise I try working in contact mode. Regards Marvin

    Hi Stefan, I'm using Micro Cantilever from Olympus with the Name OMCL-AC160TS-W2. They have their resonance frequency between 287.5 and 368.3 kHz. The liquid holder used, is the standard liquid holder made for the dimension 3100. I try to get more information concerning the holder. But my suspicion is, that the cantilever itself may not be appropriate

    Hello, I'm using a dimension 3100 and aimed to analyse chrystal growth on zinc surfaces. My problem is, that the RMS Amplitude is never above 0.6mV. As a result the AFM isn't able to generate pictures of the rough zinc surfaces. I already enabled the z-modulation and tuned it to those parameters given in the manual. This gave a slight increase
