Magnetic Susceptibility Balances from Sherwood Scientific Ltd
Sherwood Scientific's Mk1 and Auto Magnetic Susceptibility Balances are utilised for detecting and quantifying the magnetic properties of gases, liquids and solids
Our Mk 1 balance adheres closely to the Late Professor Evans' original design, whilst the MSB AUTO is a microprocessor controlled balance. Improved sensitivity, versatility and overall performance make it ideally suited to new applications in the research laboratory and industrial quality control.
MAGNETIC SUSCEPTIBILITY AT THE MOLECULAR LEVEL
The magnetic properties of a sample are determined by the nature of the electrons within its structure. Free, unpaired, electrons give rise to magnetic forces which are attracted to a strong magnetic field. The strength of the attractive force is directly proportional to the number of free electrons. Materials with free electrons are classified paramagnetic and those without are diamagnetic. Crystallinity, chemical reactions, oxidation states; anything altering a compound's electronic configuration may also change its magnetic properties.
APPLICATION OF MAGNETIC SUSCEPTIBILITY MEASUREMENTS
The following illustrates a variety of possible applications:
