Read the chemistry that defines the silicone.
Spectrally™ puts an immersion Raman probe straight into your PDMS, addition-cure LSR/HCR, chlorosilane and medical-grade silicone lines. Siloxane chain length, silanol and vinyl content, residual cyclics and cure state - read inline, directly in the reactor rather than pulled to a lab, in seconds and with no sampling or reagents.
Silicone condensation and addition cure, the chlorosilane monomers upstream, and medical-grade LSR and RTV for Class III devices.
Siloxane chain length, Si-H and vinyl crosslinking and residual cyclics - the properties that set every silicone grade, read live instead of after the batch.
The core of the Spectrally platform - it reads the diagnostic silicone bands directly, around 70% of the measurement portfolio.
Immersion probe in the reactor or line, feeding your PLC / DCS continuously.
Everything a silicone plant asks us - one page per answer.
Six focused pages: the chemistries we cover, the parameters we read, how the measurement works, the proof behind it, the regulatory context and the instrument itself.
Characterisation that lags the batch.
Residual cyclics come back from GC/MS 60 to 120 minutes later; cure state waits on gel-time or a 30 to 90 minute DSC run. By then the reactor has moved on, and the specialised chemistry has queued behind a specialised lab.
Sample, extract, run GC/MS for residual cyclics or DSC for cure state, wait, report. Inline viscometry gives a molecular-weight proxy but no composition, and NIR cannot separate cyclic from linear siloxane. The result describes a reactor state that has already passed.
The immersion probe reads the Si-H, vinyl and siloxane bands in the reactor continuously and streams values to your control system. Cure state and residual cyclics are caught while you can still act - so GC/MS and DSC become verification, not the bottleneck.
Spectrum to a process value, continuously.
Single-ppm composition sensitivity where the chemistry demands it.
One-time system cost in EUR, 75-250k by configuration.
From feasibility to a validated model on your line.
Put it on your silicone line - starting with your own stream.
Send representative samples or process data from your PDMS, LSR/HCR, chlorosilane or medical-grade silicone stream. We build and validate a chemometric model on your matrix and hand you the numbers inline Raman reads on your line - siloxane chain length, cure state and residual cyclics - benchmarked against your GC/MS and DSC reference methods.
