Hi Josep, You are on the right track. The scaling factor is just the product of the ZsensSens and the Zscale value in parenthesis. For example \@Sens. ZsensSens: V 163.0064 nm/V ... \@4:Z scale: V [Sens. ZsensSens] (0.0003750000 V/LSB) 5.966755 V ... the scaling factor for the Height Sensor channel would be 163.0064*0.000375 nm/LSB. To read the data

Thanks Ang Li, As you say, the spring constant= Sens. ForceDeflSens/Sens. DeflSens. Sens. DeflSens is available as a predefined browser column. Sens. ForceDeflSens is not, but you could set up the "User Defineable" column with this as a workaround... --Bede

Hi Gabriela, Sneddon's model is often used to fit data acquired from cells since the deformation depths on cells are often too deep for use with Hertz or JKR (unless you are using a bead for a tip). This reference has a nice discussion of the various techniques and application to cells and tissue: Lin, David C, and Ferenc Horkay. 2008. “Nanomechanics

Hi Dalia, Here are some answers for you: 1) You can use the Nanoscope Analysis browser to see the spring constants for multiple files or open the file and select File>Display properties. Unfortunately, I just discovered that the spring constant is not saved in the header of image files, only Force Plots (or other ramps). I'll request that this

Hi Fenny, You do need a key for the QNM-HSDC force curve analysis to convert HSDC data to force curves. If you have purchased PeakForce QNM you will have the realtime key on your data acquisition system, so you can use Nanoscope analysis on that system to use the QNM-HSDC force curve analysis. If you would like to do this on another system (laptop,

The magnetic force gradient leads to a resonant frequency shift of the cantilever. The phase shift related to the resonance follows this shift. Since we are driving at a constant frequency, a change in both phase and amplitude will be observed in the lock-in outputs, but phase is more popular since the contrast can be higher without big changes in signal

Since the electric field is causing the expansion or contraction of the ferroelectric material there is no need for a direct electrical connection (as would be required for TUNA or CAFM). There should be an electrode that is connected the the chuck behind the insulating layer, however. --Bede
