Specialty Polymers, US / What we measure
What we measureWhat a spectrum of a polymer process carries.
Inline means the spectrum is taken in the vessel or line itself. Each value below comes from its own model, calibrated in a feasibility study against the lab methods at each plant.
01Spectrum explorer
Five values from one spectrum.
Select a parameter to see where it sits and where it is read.
Schematic spectrum · 785 nm
Raman shift → · schematic trace for orientation
02How it is usually read
The lab methods stay where they belong.
They stay in the plants as the reference for the model and as the tests for chain length, the melt and the part.
typ. 30–60 min
GC · residual monomer, chain-growth processes
Stays as the reference for the model.
typ. 60–120 min
GPC/SEC · molecular weight
Stays in the lab: chain length is its question.
per lot
Melt and mechanical tests
Stay in the lab for the properties of the melt and the part.
per round
Manual sample draw
Taken when the lab schedules it, and less often in routine operation.
