Optical Detectors ● Photodiode array spectrometer module ● Low noise detection (<0.1 mAU peak to peak) ● Wavelength range 190 nm to 720 nm ● Fiber optic design Tidas E High performance fiber optic spectrometer systems WPI’s Tidas E is a high end photodiode array-based spectrophotometer including a light source, a cuvette holder and fiber optic coupling. Its companion is the TIDAS E Base, a fiber optic spectrometer module with a fiber optic connector for modular spectrometer systems. The Tidas family of spectrophotometers and spectrometer modules outperforms conventional bench-based spectrophotometers and CCDbased spectrometer modules, when it comes to high precision fiber optic sampling. It relies on a monolithic optical bench made by Zeiss, which is optimized for fiber optic applications. Most cuvette-based standard spectrometers lose more than 90% of light through expensive prism decoupling. The Tidas E is designed for fiber optic sampling cells. Using suitable light sources and sample cells, spectral detection in the wavelength range of 190 to 720 nm can be performed at noise levels <0.04 mAU peak to peak. SPEC TROS CO PY Applications The Tidas E is ideally suited for WPI’s fiber optic sampling equipment. High sensitivity detection systems for flow analysis can be assembled using WPI’s Liquid Waveguide Capillary Cells (LWCC) with effective pathlengths ranging from 50 to 500 cm. These setups are frequently used in fluid injection analysis systems for nutrient analysis (nitrite, nitrate, phosphate, iron) in oceanographic applications. Microliter sampling systems for UV/VIS applications can be assembled using WPI’s V-Vette or DipTip™ dipping probes. Software TidasDAQ 3 software is included with each instrument for data collection and data analysis. TidasDAQ is used to run the spectrometer module, collect spectra in either single or continuous mode, control the digital I/Os, save the experimental data to disk, and analyze the data. Further, TidasDAQ can export data directly into GRAMS/AI, a feature very useful for advanced data analysis for pharmaceutical applications and requirements.
