Detect contaminants at ppt/ppb-levels
Provides very long optical pathlength (>> 1000 m): We use high reflectivity mirrors, high quality optics and high quality electronics.
High accuracy to optimize process monitoring and control
Minimizes cross-interferences through the use of high-resolution diode laser absorption technology, low pressure and algorithms: Our unique technology produces absorption spectra with very narrow bands that can be fitted to remove the remaining cross-interference effects of other compounds in the gas stream.
T90 < 10-30 seconds allows for process control and real-time monitoring
Optimal volume-to-surface ratio, fast flow rate and coatings: We optimize the volume-to-surface ratio and use special coatingsto minimize memory effects for sticky contaminants like ammonia. When required, external pumps can provide an increased flow rate to optimize performances further.
Quick refresh rate for ultra-precise time measurement
Extremely fast electronics: We collect a single scan at 100 – 1000 Hz. Even within 0.1 second, scans can be coadded to optimize SNR significantly. User can select up to 100 seconds for further improvements.
Accurately quantify both trace and % levels for measurements during routine operation and excursion events
Effective optical pathlength decreases with absorption: Each bounce on the rear mirror means a few photons escape. The final transmission intensity is then higher than for direct absorption which increases the range before saturation occurs. ICOS also measures the ringdown time i.e. the time for the photons inside the cavity to exit once the laser is reset. This ringdown time represents the rate at which photons exit the cavity at each bounce therefore compensating the higher transmission for the analyte.
Low cost of ownership
Higher stability, minimal downtime (low maintenance)
Overall sturdiness and tolerant optical design: Our design inherently provides more stability towards vibrations, extreme temperatures and measuremet drifts through the use of parabolic mirrors that keep light within the optical path even if mechanical parts drift. We also rely on state-of-the-art components and high quality engineering and manufacturing.
Low cost of ownership, minimal downtime (field serviceable)
Smart design: Parts that can be subject to long term contamination (filters) and normal aging (pump diaphragm) or that can be exposed to abnormal amounts of contamination during extraordinary events (mirrors) can all be replaced easily, even by untrained personel when need be. Most other components can be diagnosed and replaced in the field by our service engineers.
Further reduces cost of ownership due to maintenance
Analyzer can be remotely accessed : All analyzers can be equipped with a wireless router to access the user interface, including with TeamViewer for distant internet connections by service team.
No calibration efforts needed and only infrequent verifications
1st principles measurement technology: Along with the collection of high-resolution absorption spectra, we use ultraprecise measurements of several parameters (including T°, P, ringdown time) and feed it to our in-house algorithm to resolve the Beer-Lambert law without the use of primary reference methods.
Reduces cost of ownership associated with maintenance and consumables
Sample is directly measured with little to no conditioning: Our design inherently eliminates the use of columns, carrier gas, tapes, solvents or scrubbers.
No need to periodically calibrate using zero gas
Measured spectra includes baseline: Each scan starts at a base current which is measured. If this base current shifts, the whole spectra (each scan) is compensated accordingly.
