Abstract Solid state NMR has seen a constant increase in popularity since the NMR had been first invented because it hurdled the biggest problem; inherent lack of resolution relative to solution state NMR; with many techniques. Solid state NMR serves many insights for organic and inorganic chemistry, where is used as a powerful tool to study local dynamics, kinetics as well as thermodynamics of a variety of systems. The assemblies of the NMR spectroscopy are magnet, computer, console and the probe. Of course, many factors of each assembly determine the performance of the NMR spectroscopy. Especially, the probe is the interface between a sample and the spectrometer. Its high solidity and flexibility are very important elements for supporting the maximum performances of the NMR spectrometer. Above all, the choice of probe suitable for various types of samples is needed for getting right results from NMR experiments. So we made the elaborate solid-state NMR probes for diverse sample analysis such as characterizing membrane proteins and defining of molecular dynamics in high tech devices. Here, we present the optimized design, construction, and efficiency of a home-built 400 MHz wide-bore (WB) & narrow bore (NB) 1H-15N solid-state NMR probe and a home-built 800 MHz NB 1H-15N solid-state NMR probe for lossy samples. We will also announce a home-built 400MHz and 500 MHz NB 19F-13C solid-state NMR probes for analyzing nano-materials and LCD panel respectively and 600 MHz NB 19F-7Li solid-state NMR probes with solenoidal coil for investigating Li-ion battery. These were the first application for the in-situ analysis of LCD panel and in-situ analysis of Li ion battery pack samples. And finally we will introduce our recent commission task project “Development of sample dependent Solid-state NMR probe for the analysis of nanomaterials”.
