Bartington MS2G Small Sample Sensor


. This sensor is designed for magnetic susceptibility measurements of 1 ml or smaller powder or liquid samples. The sensor operates in conjunction with the MS2 meter at a low frequency and has a high temperature stability and a resolution of 1 x 10-7 CGS (1 x 10-6 SI) volume susceptibility.

This sensor is used for susceptibility measurements where only very small samples of homogeneous fine grained material are available. Examples are airborne particulates collected in filter papers or particles in colloidal suspension.

The sensor accepts commercially available polyethelene vials with a diameter of 8 mm and a length of 30 mm. The sample holder is compatible with other rock measuring equipment allowing for a comprehensive range of measurements to be taken without the need for re-packing the sample. The sample cavity is situated at the tip of a boom mounted on the aluminum electronics module.

A detachable screw adjustment is provided for optimising the position of the vial for sample volumes between 0.2 and 1 ml. Calibration correction factors are given on a label on the sensor.
