Chemical and physical analyzes using Nuclear Magnetic Resonance (NMR).

Specfit is a national equipment that uses Nuclear Magnetic Resonance (NMR) technology to perform non-destructive, fast and highly accurate physical and chemical analysis. Its high technology allows a wide range of applications, many of them automated and without sample preparation. SpecFIT was developed with digital technology that has low obsolescence, easy upgradeability and high performance. In addition to the dedicated analysis options, we also offer different options for configuring the device with open solution for researchers to develop their own methods of analysis using NMR through a software programming of pulse sequences without the need of knowledge in computer programming.

SpecFIT Ultra

Spectrometer for image analysis via nuclear magnetic resonance (NMR).

Specfit Ultra is the equipment used for nuclear magnetic resonance (NMR) technology developed by FIT using low-obsolescence, easy-to-upgrade, low-cost, portable and high-performance FPGA technology with digital reception and transmission. With the SpecFIT console it is possible to program experiments of relaxometry (NMR-DT), spectroscopy and images through a system based on table filling, with which it is possible to program pulse sequences even without knowledge of computer programming language. It has two aesthetic models: one in the rack mount format 19" and the other in the table format.

Your NMR experiment need high quality components.

The TR/Switch developed by FIT guarantees a good efficiency of the MRI measures protecting the components of the system. The communication between console, amplifiers and coil is made so that the reception is isolated while the system is transmitting high power and vice versa, thus protecting the equipment involved in the NMR experiment. This duplexer works for different frequencies. Consult FIT about the availability of the required frequency and also duplexers with active operation.

Receiver coil

Development of the coil suitable for its application.

FIT has more than 10 years experience in developing image reels. We develop internal and on-demand designs of single-channel, quadrature, multi-channel phased array or sampled array types. Medical reels, animals, small animals, seeds etc for any scanner, low, high and very high field. 


Maintenance and Equipment Upgrade

Our electronics are digital and adaptable, so along with FIT experts, it is possible to update obsolete equipment without maintenance, reactivating them to operate as new. We give new life to that abandoned magnet.

Application Development Service

We develop NMR applications for clients in partnership with research institutions.
