4IR Comparison between NIR FT-IR and 3rd Generation NMR Technology

Abstract On-line Nuclear Magnetic Resonance (NMR) analyzers are beneficial in chemical and petroleum industries for qualitative and quantitative analyses of physical properties of process streams. NMR selectively specifies and quantifies hydrogen atoms with regard to the molecular structure of substances and their presence in mixtures. Its linear spectral response enables chemometrics to easily perform accurate […]

4IR Process analyzer system at the pipeline point of entry

The strategic importance of placing a Process NMR system at the pipeline point of entry is to verify that the pipeline tender is fully intact and meets delivery specifications.  Placement of the on-line analyzer at the point of entry verifies that the supplier’s product tender is on specification. Thus, removing liability of the supplier should such […]
