The BrightSpec Advantage
“What is it?” and “How much of it?” – the BrightSpec FT-MRR platform, based on molecular rotational spectroscopy, directly identifies molecules in complex mixtures (no chromatography needed), answering these two questions in the same rapid measurement. Low matrix interference and precise identification provide unparalleled molecular specificity. With direct sampling in vacuum, the approach is a ‘green’ alternative. In addition, low sample vapor pressures (1-5 mTorr) required to obtain baseline resolved spectra offer a gentle approach to sample introduction. BrightSpec FT-MRR spectrometers offer greatly shortened method development times, high sample specificity, ID and quantitation of trace components, and greatly reduced use of consumables.
FT-MRR Spectrometers
FT-MRR spectrometers provide sensitive, quantitative measurements for Chemical ID and Chiral Analyses. The specification of frequency range (millimeter wave or microwave) determines which of these applications FT-MRR will address, and also impacts choice of sampling method (nozzle cooled or room temp). The platform can be implemented in either a broadband or targeted configuration. For fundamental and applied research applications, broadband instrument platforms provide the greatest experimental flexibility. Streamlined configurations with targeted functionality provide seamless transfer from R&D to QA/QC environments. No matter the configuration, FT-MRR provides faster insight and improved throughput.
BrightSpec One – FT-MRR for Analytical R&D
BrightSpec One characterizes the chemical composition of complex mixtures, rapidly delivering quantitative information, without the need for preparatory purification or separation. “Dirty” liquids, headspace samples, solids, and gas mixtures are volatilized and introduced directly into the integrated sample cell. With the attributes of high specificity, high dynamic range, and baseline resolution, FT-MRR identifies sample components with almost absolute specificity before standard calibration, even for trace level components. Available sampling accessories add to the base capability of gas sampling, enabling headspace analysis, thermal evolution of solids, and direct volatilization of liquids. Integration with an optional CTC-PAL3 autosampler ensures unattended operation to maximize sample throughput.

BrightSpec Discovery – FT-MRR for Fundamental Research
BrightSpec Discovery incorporates the same spectroscopic engine as BrightSpec One. The difference is in its form factor, with Discovery employing a modular design for increased experimental flexibility. It operates in identical fashion to the BrightSpec One, but can be combined with and networked to other analytical systems. This thoughtful approach to customization enables fundamental and applied research groups to quickly generate insights on complex processes.

BrightSpec Chiral Broadband – FT-MRR for Chiral Characterization
BrightSpec Chiral Broadband is an FT-MRR platform used to differentiate diastereomers in mixtures without preparatory purification or separation. With the addition of the optional 3-Wave Mixing technology, enantiomeric excess may be determined. Operating in the microwave frequency range, and using pulsed jet nozzles to prepare rotationally cooled samples, this alternative to chromatography offers a combination of high-resolution, spectrally specific analyses for chiral characterization.
