Spin density measurement

The MS 5000 EPR system offers a simple, fast and accurate method for determining the spin density.

Background

The measurement of spin density is an application of electron spin resonance (ESR) to determine the exact number of spins in a known volume. The main physical factors in­ fluencing the measurement are taken into account.


Spin density is calculated by double integration of the ESR signal and comparison with a spin quantified standard material. The calibration values are included in ESRStudio. Also, we offer a Spin Quantified Chromium standard to calibrate individually.

User-friendly measurement with MS 5000

1.   Select recipe and enter volume

  • Possibility A: Compare un known sample with standard (automated correction by Q-factor, microwave power & modulation amplitude)

  • Possibility B: Direct measurement without calibration (instant data reporting and backup)

2.   Press “Start”

3.   Result is displayed and stored automatically.
