Spectrometer probes measure optical spectra from 210-750 nm in liquids. Robust, reliable, and durable, these devices require minimal maintenance; with automatic cleaning via compressed air or a brush. Factory precalibrated, stable and maintenance-free in operation, probes can be deployed in a water source or bypass stream for 24 hours a day for years at a time.
The "Fingerprint" refers to the comprehensive absorbance profile generated by the spectrometer. This fingerprint can be used to monitor multiple parameters simultaneously, such as chemical or biological substances in the sample. By analyzing the spectrum, the system can account for potential cross-sensitivities between parameters, making it highly reliable for complex measurements.
Global Calibrations calculate the concentrations of multiple parameters from the Fingerprint and are available as application-specific factory settings. Through the Global Calibrations each user benefits from many years of experience in applications similar to his own – in most cases no local calibration on site is required.
Our spectrometer probes use no replaceable parts or consumables. This dramatically reduces the ongoing costs associated with maintenance and replacement parts, making it a cost-effective solution for long-term use. As long as the spectrometer is operated properly, users can avoid additional costs beyond the initial purchase.
Spectrometer probes work according to the principle of UV-Vis spectrometry. The spectrometer probes are the first and only instruments in the world that can measure optical spectra from 190 to 750 nm directly in liquid media. The substances contained in the medium weaken a light beam emitted by a lamp that moves through the liquid. After contact with the medium its intensity is measured by a detector over a range of wavelengths specific to the application.
In the measuring section, which is positioned between emitting and receiving units, the emitted light passes through the medium to be analyzed. Substances in the medium between the measuring windows of the probe absorb visible and UV light. Internally a second light beam is guided across a comparison pathway. This two-beam setup makes it possible to compensate, with every single measurement, any instrumental effects that could influence the quality of the measurement (e.g. aging of the light source).
