Product description

Variable wavelength, high sensitivity, and a selection of flow cells make the Model 500 Detector ideal for liquid chromatography applications from microbore to preparative scales.

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 500 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 500 to preparative or large-scale separations. The flow cell compartment is located outside the main instrument housing for easy access.

The Model 500 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 500. Contact your distributor for more information.
