TidasDAQ: Data Collection & Instrument Control With TidasDAQ, high precision intensity, absorbance, transmittance or normalized spectra can be obtained in less than a second. Only a few parameters need to be adjusted to obtain spectral data. Sampling of single scans, continuous full spectra scans or triggered scans is possible. Chromatograms can be displayed and logged to disk at up to four wavelengths. Data Export of 2D and 3D Spectrograms, as well as Chromatograms is supported in ASCII, Spectralys/SpectraView, Excel and Grams/AI formats. Light sources and other sampling instrumentation can be controlled via the TTL level digital outputs, as well as data collection can be triggered by TTL leveled external inputs of the TIDAS E. Spectra can be recorded in 2D and 3D view. Mathematical computation, Derivation, Smoothing, Quantification and other functions are available to work with your data. The Quantification module allows single point and multiple point analysis, multiple linear regression, partial least square and principle component analysis. Data can be exported out of a 3D analysis file into separate scans. Further, chromatograms as well as spectrograms can be copied directly into Excel for further data analysis.

The TIDAS E Optical Path With help of the patented cuvette holder and the mirror cuvette, various measurement setups are possible in conjunction with either internal or external light source. The patented cuvette holder and the external measurement setup can be simultaneously used. The flexibility of the design of TIDAS E is manifested below in various possible options of measurements using different optical paths formed by combinations of cuvette holder, mirror cuvette, optical fiber and light sources. Figure 2: Spectra can be displayed and analyzed in 2D and 3D format. This allows the user to conveniently interpret “time acquisition” data typically done with a TIDAS-E-BASE-LWCC flow system.

The light from the external light source is coupled over the cuvette holder and redirected over the mirror cuvette to the detector. The light radiates from the internal light source, and is conducted from the redirected mirror, through the cuvette holder, into the correct detector. The measuring sample can be located in the second cuvette chamber. From the internal light source, radiated light passes through the cuvette holder and illuminates through the external measuring cell. The light is redirected through the cuvette holder and channelled through the detector.
