Description | The V-770 UV-Visible/NIR Spectrophotometer features a unique single monochromator design for maximum light throughput with excellent absorbance linearity. A PMT detector is used for the UV to visible region and a Peltier-cooled PbS detector for the NIR region. | The FVS-6000 Vibrational Circular Dichroism Spectrometer measures both IR absorption and VCD, and provides accurate and highly sensitive measurement in the fingerprint region. The FVS-6000 optical system uses a 28° interferometer with gold coated corner cube mirrors for high throughput and to The FVS-6000 Vibrational Circular Dichroism Spectrometer measures both IR absorption and VCD, and provides accurate and highly sensitive measurement in the fingerprint region. The FVS-6000 optical system uses a 28° interferometer with gold coated corner cube mirrors for high throughput and to minimize polarization effects with reflective optics to eliminate artifacts caused by birefringence, resulting in very high-quality VCD data. The FVS-6000 uses a unique highly sensitive narrow-band MCT detector specially developed for VCD measurement across the spectral range 3,200 to 850 cm-1. Optional detectors and filters can be added to extend the range to 4,000 to 750 cm-1, typically for measurement of -OH and -NH bands. Detectors are easily exchanged without the need for manual alignment, and optical filters can be selected automatically....

The J-1500 allows for the maximum flexibility to upgrade your CD system with different measurement techniques. While the standard measurement modes are CD, LD, and absorbance, up to four simultaneous modes can be measured when combined with a wide range of sampling accessories. These accessories can measure a variety of samples, from liquids to films to solid-states. Temperature control systems can be coupled with multi-position cells to run thermal melts, providing researchers with CD and thermodynamic data sets for conformational and folding studies. Automated high-throughput CD can obtain measurements on up to 192 samples without user intervention, saving both time and money. Kinetic and protein dynamics studies can be performed with our dedicated stopped-flow systems that can measure both CD and fluorescence. The wavelength range has also been significantly extended, allowing measurements to be obtained in both the vacuum-UV and NIR spectral regions using the standard PMT detector (163 to 950 nm) and an optional InGaAs detector (up to 1,600 nm). Additional features now allow researchers to optimize their parameter specifications in order to obtain data with the highest resolution and S/N performance for a specific application set....

The J-1700 was specifically designed for more demanding near-infrared CD applications. In addition to the enhanced far-UV capabilities, researchers probing the chiral activity of molecules in the NIR spectral region now have the ability to obtain data at wavelengths up to 2,500 nm. The InGaAs detector has a wavelength range from 900 to 2,500 nm, while the PMT ranges from 163 to 960 nm. The automatic detector interchange allows researchers to obtain both far-UV and NIR measurements without having to manually switch detectors. The addition of a grating monochromator to the double-prism monochromator setup provides low stray light and high light intensity, generating CD signals with high S/N performance throughout a large spectral range....
