Magnetic Susceptibility Systems from Bartington Solve Diverse Challenges Ranging from Ventilator Production to Herbicide Dosing

Magnetic susceptibility systems from Bartington Instruments have been demonstrating their ability to solve diverse problems lately, ranging from aiding production of ventilators for Covid-19 patients to helping optimize herbicide treatments for agriculture. 

In November, the company was recognized for its “invaluable contribution to the Ventilator Challenge UK team”. Its MS3 meters, shown at top, and MS2B sensors are used to aid ventilator production, which has been vital during the Covid-19 pandemic. With patients wearing ventilators throughout their treatment, ventilators may be used in magnetic resonance environments. It is essential to ensure that components used in ventilator masks are non-magnetic. The MS3 and MS2B measure the magnetic susceptibility of the components, to check that they are safe for use — a crucial step, as supply chains are expanded during this period of increased demand. 

The MS3 meter, combined with one of the company’s MS2 sensors, shown above, makes a versatile magnetic susceptibility system. The wide range of sensors is designed to match a variety of sample types including soils, rocks, powders and liquids, and is suitable for laboratory and field use. 

In another recent example, Bartington reports that Sao Paulo State University has discovered that using its MS2B sensor to measure soil magnetic susceptibility reliably predicts the adequate dosage for the herbicide imazaquin. The sensor makes possible low-cost soil analysis and farmland mapping, via quick, easy and non-destructive testing, without previous sample preparation. Correlating imazaquin absorption with soil magnetic susceptibility results in reduced losses and reduced environmental contamination by minimizing the use of the herbicide. 

Based in the UK at Witney, west of Oxford, Bartington designs and manufactures high precision fluxgate magnetometers, gradiometers, magnetic susceptibility instruments, Helmholtz Coil systems and associated data acquisition equipment. Around 80% of its products are exported worldwide to customers working in varied market sectors, including defense, surveillance, space, physics, geophysics, industry, archaeology, and oil and mineral exploration.
