SADER METHOD

Enter frequency, quality factor and spring constant measured using the Thermal Method. Press UPLOAD & CALCULATE. The entered data is uploaded to the database and the Sader Method (described in THEORY) gives you a new calculation of your spring constant... Enter the frequency and quality factor only. Press CALCULATE. The Sader Method uses the existing database to calculate your spring constant... The Global Calibration Initiative uses measurements from the international AFM community to perform non-invasive calibration of AFM cantilevers (of any geometry) with the Sader Method. A live database lets users instantly compare their calibration measurements to those of others in the community, while systematically refining their own calibration using others' data. The GCI provides a reference point for worldwide calibration, enabling force measurements from different labs to be compared directly.
