Variable wavelength, high sensitivity, and a selection of flow cells make the Model 795 Detector ideal for liquid chromatography applications from microbore to preparative scale.
A direct mechanical drive on the unit’s front panel sets the desired wavelength. The standard deuterium lamp covers UV wavelengths; an optional tungsten lamp is available for visible wavelengths. The lamps are prealigned, readily accessible, and can be easily changed.
The Model 795 features 12 switch-selectable absorbance ranges. Low-noise electronics, high-noise rejection filtering, and low-loss optics preserve the detector’s high sensitivity and ensure low-noise, low-drift performance.
Flow cells are available to support a full range of applications, from microbore to prep. These cells eliminate dead volume and minimize refractive index contributions. The standard is a 6 mm, 9 µL, Type 316 stainless steel cell for analytical HPLC applications. Kel-F flow cells are available for biocompatible applications; flow cells for microbore and capillary electrophoresis applications are also available. A variable path length (0-3 mm) prep cell can be used to adapt the Model 795 to preparative or largescale separations. The flow cell compartment is located outside the main instrument housing for easy access.
The Model 795 also features autozero and event marking using front and rear panel controls. The unit can be zeroed manually from the front panel or automatically using an event switch connected to the rear panel.
A variety of flow cells and other detector accessories are available for the Model 795.
Maximize sensitivity through continuously variable wavelength optimization
A standard prealigned deuterium lamp and optional tungsten lamp cover the entire UV/Vis spectrum, giving you the ability to work at max.
Convenient front panel controls
A front panel mechanical drive lets you quickly and accurately select and display on the readout any wavelength in the lamp\'s range. Push-button diagnostics add to the user-friendliness of this detector.
Manual or remote autozero
Rezeroing the baseline is done at the push of a button or through a remote-controlled event for automated systems. Event marks can also be generated either from the front panel button or via remote TTL/contact closure signal.
High sensitivity for your most demanding applications
A 12-position front panel switch allows range settings from 0.0005 to 2.0 AUFS. The second-order Bessel filter, fiber optics, and proprietary circuitry make this the most sensitive detector available.
Flow cells for every application
Flow cells are available in Type 316 stainless steel or chemically inert, biocompatible Kel-F®*, for applications from microbore to preparative scale. Superior design gives unmatched versatility and performance.
Easy access and maintenance
Easy access to the flow cell and lamp ensure quick maintenance and minimum down-time.
