Software:

  • Linux software by N.R.Nowaczyk.

Analytical performance:

  • Measurement of magnetic susceptibility of discrete samples versus field and/or frequency. The original manual operation has been replaced by a simple (currently experimental) stepping motor controlled automation.
  • NOTE: The mains frequency (Germany: 50 Hz) and its multiples have to be avoided! Thus, useful frequencies are f = n*50+25 Hz.

Sensitivity:

             100 µT 400 µT
             100 Hz : 10e-5 100 Hz : 2x10e-6
             1000 Hz : 10e-6 1000 Hz : 2x10e-7
             10000 Hz : 10e-7 10000 Hz : 2x10e-8

Application:

  • Rock magnetic investigations of terrestrial, lacustrine or marine sediment sequences, or hard rocks.

Sample types:

  • cubic or cylindrical samples with up to 10 ccm volume.
