microESR by Bruker BioSpin

The microESR is a small, portable research grade instrument. The spectrometer has a mass of only 10 kg and a 30.5 x 30.5 x 30.5 cm3 foot print. It can easily fit in a fume hood or glove box, or be transported to the field. It requires no special installation or regular maintenance.

Education

The microESR is also an ideal teaching tool for undergraduate chemistry labs. This instrument enables classroom demonstrations of both simple topics such as free radicals in everyday life to far less intuitive subjects including electron density, spin-orbit coupling, spin-spin exchange, and forbidden transitions. The Education Package is a very good investment for Chemistry Departments as there are a wide range of labs and subjects that can be addressed with the microESR.

• Operating Frequency: X-Band
• Continuous Wave
• Field Sweep Range: 500 G centered at g=2
• Spectrum simulation and fitting
• Easily run samples at liquid nitrogen temperature

Edible Oil Analysis

Rancidity of edible oil is a major problem in food related industries. It occurs during storage and is caused by oxidation of unsaturated fatty acids, resulting in foul odors and tastes in the final product.

Bruker has developed a benchtop electron spin resonance instrument and software solution specifically for measuring oxidation and shelf life in liquids. The combined system and SOP provide an easy work flow for measuring oxidation profiles in liquid samples. The key metrics such as induction time and end-point free radical concentration are automatically calculated.

Fast, accurate determination of oxidative resistance allows manufacturers to make timely, informed process control decisions.

• Determine Oxidative resistance in as little as 30 minutes
• Measures free radicals instead of end products
• Includes SOP for sample preparation and analysis
• Compact lightweight with very small footprint
