Introduction

Veli-Pekka Viitanen is a notable inventor based in Huhmari, Finland. He has made significant contributions to the field of nuclear magnetic resonance (NMR) technology. With a total of two patents to his name, Viitanen's work focuses on measuring the water content in various samples.

Latest Patents

Viitanen's latest patents include a Low-field NMR device for measuring the water content of solids and slurries. This invention features a Nuclear Magnetic Resonance apparatus designed to measure the water content of samples. It includes a device to produce a main magnetic field, a sample receiving space, and a mechanism to excite measurable RF magnetization in the sample. The device also measures the RF signal produced by the excited sample and determines the water content based on this signal. The sample receiving space can accommodate samples with a volume of at least 0.5 dm, and the main magnetic field is generated by a resistive electromagnet operating at frequencies between 400-2000 kHz.

Another significant patent is the method and apparatus for varying adaptively pulse interval in NMR-based water content measurement. This invention relates to an NMR method for determining moisture content in a sample. The method involves subjecting the sample to a magnetic DC-field and a sequence of excitation pulses in RF-frequency. The NMR signal of the excited hydrogen nuclei is measured, and the spin-lattice relaxation time is estimated to adjust the pulse interval accordingly.
