WebPeakForce Tapping™is a proprietary Bruker AC imaging technique where the cantilever is oscillated but well below resonance. This oscillation results in a continuous series of force-distance curves requiring no tuning. As such, the method is inherently stable. Learn more about PeakForce Tapping on Bruker.com. Category Probes (14) Application WebQNM operates over an extremely wide range, approximately 1 MPa to 50 GPa for modulus and 10 pN to 10 µN for adhesion, enabling characterization of a large variety of sample types. Because it is based on Bruker’s proprietary Peak Force TappingTM technology, the forces applied to the sample are precisely controlled and a variety of probes can be
