By attending SciX, we continue to expand our reach and services in providing dispersive optical spectrometers and systems into established and emerging markets," states Andrew Boorn, Chairman and CEO at Tornado Spectral Systems.
Although the proposed spectrometer covers a spectral range in the VIS regime, it may not be directly competitive with commercial interferometric spectrometers, because they typically span the full UV-VIS or VIS-NIR spectrum.
The most commonly used molecular spectrometers are UV-Vis and fluorescence instruments, while mass spectrometers (measuring accurately the mass of selected ions of interest) have become the detector of choice for commonly used separation systems, including gas, liquid and ion chromatography systems.
