A high sensitivity UV-Visible/NIR Spectrophotometer with InGaAs detector for wavelengths up to1600nm
The V-780 UV-visible/NIR spectrophotometer features a single monochromator with automatically exchanged gratings: 1200 lines/mm for the UV-Visible region and 600 lines/mm for the NIR region. A PMT detector is used for the UV-Visible region and a high sensitivity InGaAs detector in the NIR region. Both gratings and detectors are automatically exchanged within a user selectable range of 800 to 900nm.
The V-780 spectrophotometer is operated using Spectra Manager™ Suite. This innovative cross-platform spectroscopy software is compatible with Windows 7 Pro (32- and 64-bit) and Windows 8.1 operating systems.
For simple operation, the handheld iRM includes a colour touch-sensitive screen. Data can also be downloaded for further PC data processing. Both Spectra Manager Suite and the iRM provide full control and advanced data processing, and with optional 21 CFR part 11 compliant versions
The V-700 Series has a growing list of software applications for both Spectra Manager™ and iRM. If you have an application which you don’t see listed, please let us know as we may already have it or we can prepare an application designed specifically for your requirements.
The IQ Accessory function provides automated accessory recognition. The spectral data files include instrument and accessory information and serial number. IQ Start together with the Start Button can be used to to start a method for routine measurements.
The V-780 UV-visible/NIR spectrophotometer is used for spectroscopy in the wavelength range 190nm to 1600nm with enhanced sensitivity (compared to a PbS detector) in the NIR region using an InGaAs detector. The single monochromator design offers a higher energy throughput compared to a double monchromated instrument, resulting in a higher S/N ratio throughout the entire spectral range, even using narrow spectral bandwidths.
An extensive range of accessories is available for the V-780 UV-Visible/NIR spectrophotometer for virtually any biological, material science or routine QA/QC measurement. Please refer to the instrument brochure for accessories specific to this instrument.
Options include a wide variety of liquid cell holders, micro and ultra-micro cell holders, flow cell units 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 across the V-700 instrument systems.
The V-780 includes user-selectable validation to USP, EP and JP (or manually editable). With optional IQ/OQ.
