JASCO｜UV-Visible/NIR Spectrophotometer
Feature :
- IQ Accessory and IQ Start: IQ Accessory provides automated accessory recognition with automatic loading of a user defined method. Spectral data files include the instrument and accessory information while designated instrument parameters can be configured and loaded for optimum sample measurements. IQ Start together with the Start Button is used to start a sample method for immediate access when making routine measurements.
- Enhanced Sensitivity in the NIR region: The V-780 UV-visible/NIR spectrophotometer is used for spectroscopy in the wavelength range 190nm to 1600nm with enhanced sensitivity in the NIR region using an InGaAs detector. The single monochromator design offers a higher energy throughput, resulting in a higher S/N ratio throughout the entire spectral range, even using narrow spectral bandwidths.
- Sampling Accessories: An extensive range of accessories is available for the V-770 UV-Visible/NIR spectrophotometers for virtually any biological, material science or routine QA/QC measurement.
- Options include a wide variety of liquid cell holders, micro and ultra-micro cell holders, flow cell holders and accessories for solid samples. Advanced accessories, including automated cell changers, sippers, integrating spheres, automated and manual absolute reflectance accessories and programmable temperature control systems are available for any of the V-770.
- Instrument Validation and Regulatory Compliance: The V-770 includes user-selectable validation to USP, EP and JP (or manually editable). With optional IQ/OQ.
- Double-beam spectrophotometer with Single monochromator
- Photomultiplier tube detectors and Peltier cooled InGaAs photodiode
