A precise, fast technique
The company found that Analect's Fourier transform infrared (FTIR) system offered several advantages over using multiple dedicated analyzers. Compared with other technologies, such as gas chromatography and other physical-property analyzers, the FTIR system provides exceptionally precise measurement of a number of physical properties and chemical components in a very short time. Analect's FTIR spectrometer can obtain results in about two minutes. In addition, a single FTIR system
replaces many single-property analyzers, and low-skilled personnel can operate the system after about two hours of training.
From lab to factory
Knowing that all lab applications would eventually be candidates for online analysis, the oil company said it was also impressed that the FTIR system can function in the heat and vibration extremes of the process environment. The patented Transept design features a moving wedge and fixed cube mirrors, and the automated sample introduction system lowers the chance of operator error. The results are validated automatically by checking that the spectra of any new unknowns are adequately fit by the model calibration.
The oil company has found the system so beneficial that it has implemented it in facilities around the world -- a sure measure of success.
