Why measure directly in the melt?

In extrusion, the key properties of the final product – composition, color, dispersion of additives, contamination or degradation – are defined while the material is still molten. Yet in many plants, quality is still checked afterwards: samples are taken, cooled, prepared and analysed in the laboratory. By the time the result is available, the process has moved on, and any off-spec material has already been produced.

ColVisTec’s product-contact optical probes are installed directly in the extruder or melt line. They measure the material at the very point where quality is created – without sampling, without off-line analysis delays and without interrupting the product flow.

What does inline process monitoring mean?

Inline means that the measurement becomes part of the process itself. Spectra are recorded continuously on the flowing product, every ten seconds or faster, so that 100% of the output is inspected instead of a few random samples. Deviations become visible within seconds and can be corrected before they turn into waste.

Feedback time of off-line laboratory analysis compared with inline measurement

Feedback time: off-line analysis vs. inline measurement

Off-line laboratory analysis Inline monitoring with ColVisTec
Sampling Manual, product taken out of the process None – measurement in the product stream
Feedback time Minutes to hours Seconds
Coverage Random samples 100% of the output
Reaction After the fact In real time, before waste is produced

Our position: specialists in inline spectroscopy for extrusion

Complex flow processes require reliable Process Analytical Technology (PAT). ColVisTec focuses on making spectroscopy work inside real production processes: we combine UV/Vis, NIR and Raman spectroscopy with probes designed for the extruder environment and with software that turns spectra into process information. This allows our customers in pharmaceuticals, plastics and polymers, recycling, chemicals and paints & coatings to maximize process up-time, minimize product waste and guarantee the quality of every batch.
