Web• In 1974, D. F. Evans of Imperial College, London, developed a new type of magnetic susceptibility balance suitable for semi‐microscale samples, which is commercially available from Johnson Matthey. • The Evans balance employs the Gouy method in a device that is compact, lightweight, and self‐ contained.

WebThe equation for calculating the susceptibility is explained in the manual for the magnetic susceptibility balance. The equation is: c g = C bal • l • (R-R 0) χ m = χ g •M 10 9 m where C bal = balance calibration constant = 1.006 cm 2 l = sample length (cm) m = sample mass (g) R = reading for tube plus sample R 0 = reading for empty tube WebThe Gouy method is simple and may be found in many chemistry laboratories. The principle of operation uses the fact that the attraction force into the uniform magnetic field is proportional to the volume susceptibility.The Gouy balance (Fig. 3.28) measures the apparent change in the mass of the sample as it is repelled or attracted by the region of … エクセル 行 409以上
