Sherwood MK1 Magnetic Susceptibility Balance, 1 Item SHEW71000000

Sherwood Model MK1 Magnetic Susceptibility Balance
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
