| Using fiber-optic based sample cells and light sources, high-end detection systems with exceptional sensitivity and noise performance can be easily assembled. Using our liquid waveguide capillary cells (LWCC), absorbance based detection system with effective pathlengths as long as 500 cm and noise levels as low as 0.1 mAU can be achieved at reasonable cost. Microliter sampling systems for UV/VIS applications can be assembled, using our SpectroPipetter (SPT-2), DipTip™ or MicroVette™, as well as fluorescence-based systems.
More light through fitted optical construction
TIDAS I and TIDAS II are high precision detection systems based on fiber optic design. All components are made to match to one another and are “calculated” rather than “tried out”. The detectors in both units are monolithic diode array modules, made by Zeiss. Only in the TIDAS series, e.g., a multi-layer Zeiss light filter with maximum light-gain for second order suppression can be found. Detection tolerance is improved in comparison to conventional diode array spectrometers. Most cuvette-based standard spectrometers lose more than 90% of light through expensive, complicated and inefficient (or even non-functioning) prism decoupling. The TIDAS I and TIDAS II are designed for fiber optic sampling cells. The TIDAS I spectrometer module is a high performance and low noise detector for modular sampling systems. TIDAS II is a full range UV/VIS spectrophotometer with a unique multiplexing technique allowing virtually zero loss connection of external fiber optic sample accessories such as WPI’s MicroVette, DipTip, SpectroPipetter or LWCC.
Software
WPI offers three data collection and analysis packages. Spectralys™ collects and analyzes data for discrete and continuous sampling. TidasDAQ is an instrument driver, which collects data from a TIDAS I or II and imports it into GRAMS/AI, a comprehensive data processing and data management software package. TidasQuad is an instrument driver, which can manage up to four channels simultaneously using a single TIDAS I spectrometer module. This instruments driver collects data and imports it into GRAMS/AI for data processing.
Spectralys™, a unique software package for TIDAS I and TIDAS II
With Spectralys, high precision absorbance or transmittance spectra can be obtained in less than a quarter of a second. Only a few parameters need to be adjusted to obtain and analyze spectral data. Some key features of the Spectralys software package include ease of use, simple spectra acquisition, extensive online help, as well as tools for sample qualification, quantification, validation and quality control. Data can be imported from and exported to different spectrophotometer formats. The project-based approach of taking samples within an experiment allows easy documentation. Extensive calculation features allow to process your data (derivatives, smoothing, log, normalized, baseline and peak analysis). Spectralys and its optional analysis packages further offer concentration measurements, color analysis, enzyme activity and many others. A very useful feature of the software is its extensive kinetics functions.
Spectralys requires Windows 2000 as an operating system.
