Run NMR Samples Without Leaving the Chemistry Lab
Spinsolve is a groundbreaking multinuclear NMR spectrometer that offers the best performance of any benchtop system currently available in the market. The low cost, low weight, and small footprint of Spinsolve enable high-resolution, powerful NMR spectroscopy in the chemistry lab, apart from other analytical instruments such as GC, IR, MS, LC, FTIR and Raman systems. Spinsolve is now available in various convenient models.
For analyzing petroleum products like kerosene, gasoline, and jet fuel, the total hydrogen content is a highly significant parameter. A higher hydrogen content could lead to superior combustion and ignition properties of fuels. Valuable information related to the catalyst performance can be obtained by comparing the hydrogen content of products and feedstocks in the catalytic cracking process.
The aromatic hydrogen content is another useful parameter for the analysis of petroleum. For instance, the aromatic hydrogen content offers valuable information about the properties of petroleum, such as the K factor.

Conclusions
The Spinsolve Benchtop NMR spectrometer can be used to precisely and accurately measure the total and aromatic hydrogen content of gas, oils and other fuels. The sample can be prepared in a simple manner using small quantities of analytes and solvents. For each sample, the measurement period is short, and the results can be processed and reported in a completely automated manner.
