"Real-time" chemometrics as envisioned by the union of instrument control,
data acquisition, and chemometric analysis with a single software platform
can provide substantial benefits to manufacturing concerns that require pro
cess control. Some of these benefits include faster generation of informati
on and improved quality control. This paper describes a series of chemometr
ic routines written in LabVIEW and demonstrates their use in predicting six
properties of diesel fuel. In particular, near-infrared spectral data were
used to predict the boiling point at 50% recovery, cetane number, density,
freezing temperature, total aromatics, and viscosity for a series of diese
l fuels.
