The K-2600 Spectrophotometer is a programmable rapid scanning detector for HPLC and can record multiple chromatograms at different wavelengths.Acquire Data at Different Wavelengths
Multiple chromatograms can be simultaneously acquired at different wavelengths. In the »stand-alone« mode the detector offers two adjustable wavelengths per run, while four wavelengths are available if externally controlled.
GLP Functions
The K-2600 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-2600 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-2600 Detector for practically all HPLC applications.
Compact
The small footprint allows the K-2600 Detector to be installed practically anywhere.
Easily Integrated into Systems
The K-2600 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.
