SHERWOOD BALANCE MAGNETIC SUSCEPTIBILITY MK1

BALANCE MAGNETIC SUSCEPTIBILITY MK1, Magnetic Susceptibility is defined as “The ratio of the intensity of magnetism induced in a substance to the magnetising force or intensity of field to which it is subject.” THE SHERWOOD MK1 EXHIBITS MANY ADVANTAGES COMPARED WITH THE GOUY BALANCE: • Ease and speed of use; place the sample tube in the balance and get an immediate digital read out. • Measurements can be made on a wide range of diamagnetic and paramagnetic materials. • The fixed sample tube allows susceptibility measurement of solids, liquids and gases. • The technique has comparable sensitivity and is as accurate as traditional methods of measurement. • The cost of the balance is significantly lower than a complete Gouy balance system. • The instantaneous digital read-out can be used to calculate magnetic susceptibility using a simple equation. This gives significant time savings in both set-up and measurement. • Small sample size; normally a sample weight of around 250mg is used but by using a narrow bore sample tube, as little as 50mg is required to give an accurate measurement. • Analogue output: Using a flow cell allows a chemical reaction resulting in a change of susceptibility to be monitored dynamically. This allows new applications to be investigated, for example, redox reactions. • External power supply: The MSB is a low voltage instrument enhancing the safety aspects by removing high voltage from the detection end in contact with the chemicals. • The equipment is compact, lightweight and hence, easily portable
