Spectrally X1 INLINE - built for the line.
A process Raman analyzer for continuous composition measurement directly in the installation - 24/7, no sampling, no downtime.
A process Raman analyzer built for the line.
Spectrally X1 INLINE measures chemical composition directly in the installation - 24/7, without sampling and without consumables. The spectrum is acquired in the process, the result arrives in seconds, and the value streams to your control system continuously.
Two excitation wavelengths are available - 785 nm and 1064 nm, the latter for strongly fluorescing media - at 600 mW and 800 mW respectively, limited to 30 mW for ATEX applications. Detection is a back-thinned, TEC-cooled CCD with a proprietary TEC controller.

The part of the system that lives in your process.
An immersion Raman probe for direct in-situ analysis - no sampling, no conditioning loop. Rated to 16 bar and +125 °C, pH 2-10 in continuous service and 1-14 short-term, with IP67 ingress protection and an ATEX / IECEx Zone 0 rating.
The probe measures in reactors, pipelines and process tanks, in batch and continuous operation. It handles liquids, suspensions and slurries; powders and granulates run in a dedicated configuration.

Dual fiber-optic connection
Separate excitation and collection fibers simplify installation and improve signal stability. The probe connects to the analyzer over a fiber-optic cable - up to 100 m of reach.
Immersion install, no bypass
Mounts directly in the reactor, pipeline or tank via flange, Tri-Clamp or retractable process holder. No sample extraction, no conditioning system between the process and the measurement.
Zone 0 by design
ATEX / IECEx Zone 0 rating, 316L housing with POM-C ESD in the ATEX version, and laser power limited to 30 mW for ATEX applications.
Probe at the process, analyzer cabinet up to 100 m away.
Process rating of the immersion X1 PROBE, up to +125 °C.
Across a 300-1650 or 300-3500 cm⁻¹ spectral range.
Two measurement points per analyzer, expandable on request.
From raw spectrum to an operational answer.
Spectrally OS is the analytical layer of the platform. It translates spectra into concentrations and ratios, flags deviations, raises alarms and writes the quality record - locally, on the analyzer.
Three model classes do the work. CNN for pattern detection and classification of complex spectra. PLS for multiparameter regression - spectrum to concentration, for example phenol or urea. PCA for dimensionality reduction and anomaly detection.
| Supported instruments | Spectrally X1 LAB / X1 PORTABLE / X1 INLINE |

| Spectral database | Proprietary + public, ~28,000 spectra |
| Operator interface | SpectrallyUI, touchscreen |
| Operating system | Debian GNU/Linux 13.2 |

Deviation flags, not just numbers
PASS/FAIL classification, anomaly detection and batch-conformity checks against specification. Alarms and quality reports are written for plant operators, not spectroscopists.
A model lifecycle, not a black box
Calibration, validation, maintenance. Models start in feasibility on your samples, are refined on production data, and re-calibrated when recipes change. Every model change is logged and auditable.
No line stop for updates
Model updates deploy without stopping the analyzer or the line. Measurement and local logging keep running if the network drops - data lives in the local database.
One software layer across the Spectrally family. Models built during feasibility on Spectrally X1 LAB migrate to Spectrally X1 INLINE in production - the same analytics, moved from the lab bench to the line.
What changes against FT-IR, NIR and offline methods.
The differences are physical, not promotional. These are the factual points that matter for aqueous process streams - and the two cases where Raman is not the right tool.
Where Raman is not the answer
The point is not to abolish the reference. HPLC and titration remain the analytical reference methods - inline Raman moves the measurement into the process, where decision time and continuity matter, and leaves the offline methods as periodic verification.
The installation, in practical terms.
What the analyzer needs from your plant, and what it does not.
The probe sits at the process. The analyzer cabinet can sit up to 100 m away, connected by fiber.
One analyzer serves two measurement points. More channels available on request.
Runs against a reference integrated in the probe - no manual recalibration routine.
From power-on to measurement. Continuous 24/7 operation after that.
Utilities
230 V AC, 50/60 Hz, 300 W power draw. Operating environment 0-45 °C and 20-70% RH, non-condensing.

DN32/40/50 PN16 flanges; ANSI 1¼", 1½" and 2" Class 150; 1¼" male NPT; 2" and 1½" Tri-Clamp; retractable process holder. Custom designs on request.
No consumables
No reagents and no consumables in routine operation. Rated laser lifetime is a minimum of 2 years.
Service and model upkeep
Installation and service are performed by authorized Gekko Photonics technicians. Model maintenance runs through Spectrally OS - validation, re-calibration when recipes change, deployed without stopping the line.
Put the analyzer through your chemistry first.
Send representative samples or R&D data from your process. We build and validate a chemometric model on your matrix in the Gekko lab and report what Spectrally X1 INLINE would read on your line - before any hardware decision.
