The K-2001 Detector is a filter detector for HPLC and has been developed specially for use in simple routine analysis.Four Filters
The unit is supplied as standard with a deuterium lamp and four filters at wavelengths 200, 220, 254 and 280 nm. It is possible to insert two additional filters if required. Filter selection is programmable and filter changes during a run are possible.
GLP Functions
The K-2001 Detector provides GLP functions such as: detailed reports, displaying the total hours of lamp operation, total number of lamp ignitions, and more.
Fiber-Optic Options
The use of fiber-optic guides permits the spacial separation of the K-2001 Detector and flow cell, which makes operation with externally thermostatted cells or in hazardous areas possible. Fiber-optic guides are available in standard or customised lengths.
Large Selection of Flow Cells
A large range of flow cells, from nano-HPLC cells for flowrates above 100 nL/minute to preparative cells for flowrates up to 10000 ml/minute, offers maximum flexibility and permits use of the K-2001 Detector for practically all HPLC applications.
Compact
The small footprint allows the K-2001 Detector to be installed practically anywhere.
Easily Integrated into Systems
The K-2001 Detector is of modular design, easy-to-use and easy-to-maintain, which allows it to be integrated easily into existing systems as a module.
