The same signal chain and the same model stack, packaged for where the measurement has to happen — a bench, a warehouse gate, a reactor loop. A model built on one instrument runs on the next without being rewritten.

Most deployments start in a laboratory and end in the line. That path only works if the analyser that validates a method and the analyser that runs it every day share one architecture.
A benchtop analyser for identification and material characterisation, including through transparent packaging. It is where a measurement method is developed and validated before anything is mounted on a line.
LAB+ adds spectral library matching against more than 28 000 reference spectra, proprietary and public. Useful when the question is “what is this” rather than “how much of it is there”.
Incoming goods, field diagnostics, a second opinion on a suspect drum. Built-in models and libraries give a pass or a fail at the gate, through sealed packaging, without opening the container or sending anything to a laboratory.
Continuous measurement in the installation itself, feeding the control layer directly. Two measurement channels as standard, more on request; explosion-hazard zones depending on configuration, where the laser is limited to 30 mW.
An immersion probe for liquids, suspensions and slurries in reactors, pipelines and tanks. In fouling media it works with a retractable self-cleaning module — retract, rinse, return — so continuous measurement is never stopped to clean an optical window.
The models, the operator interface, the audit trail and the integration live here — the same layer whichever body the instrument came in. Model updates roll out without stopping the analyser or the line, and measurement continues when the network does not.
The family shares one signal architecture and one chemometric stack, so calibration work does not get thrown away at the step where it usually does — the move from laboratory to production.
A method developed on X1 LAB migrates to X1 INLINE without being rebuilt: same optical geometry, same detector behaviour, same model format in Spectrally OS. The feasibility study on three to five samples is therefore not a throwaway exercise — it is the first calibration of the production system.
Retractex, the self-cleaning retraction module used with X1 PROBE, is a component in that chain rather than a product of its own.
How the cabinet and probe are actually connected to a running line, and how the laboratory path feeds it: inline and laboratory.
From the 2026 product catalogue. Where a value depends on configuration, the configuration is named.

Reference spectra behind library matching on X1 LAB+ — proprietary plus public collections. The number that decides whether an unknown drum can be identified at all.
A one-hour workshop usually settles it: where the measurement has to sit, what the medium does to an optical window, and what the control system needs to receive.
