A variable filter array spectrometer can help defeat the environmental restraints of traditional infrared spectrometers.

NIR-CI adds a completely new dimension to conventional spectroscopy.

This installment provides a wrap-up of the 18th International Forum for Process Analytical Chemistry.

This installment examines one of the key differences between the Near-IR and Mid-Range IR and highlights a couple of applications where Mid-IR can be effectively employed as a process analytical technology (PAT).

This second installment in the pair looks at NIR applications performed at-line and on-line, as well as some points to be considered in implementing NIR as a process analytical tool.

Rapid near-infrared spectroscopy measurement near the process line of lab applications may speed up the process.

The author describes applying validation principles originally designed for lab instruments to process instruments.

The author discusses the process analytical technologies initiative and its effect on spectroscopy.
