Feature :

• Unparalleled Sensitivity

The new axially irradiated cell design enables the very highest sensitivity detection. These changes have resulted in a leap in sensitivity with signal noise ratio of 2300:1 or higher (water Raman peak). The FP-4025 is an excellent routine fluorescence detector that has a water Raman S/N of 1400:1.

• Dual Wavelength Measurement

Both detectors can be used for simultaneous detection at two wavelength pairs; excitation and emission wavelengths can be changed during the acquisition using a time program and automatic spectra scanning can be triggered manually, by time or automatically by threshold. A built-in mercury lamp enables automatic wavelength correction and the front-access design allows easy replacement of the flow cell assembly and light source.

• Spectral Scanning

Excitation and emission spectra can be scanned using ChromNAV chromatography data system and can be set to operate, manually, at a specified time or using a threshold trigger.

• Control

Individual LC-4000 Series instruments are normally used as part of a complete HPLC system, however for applications (such as adding to a third party system or for a non-LC application) that require stand-alone operation, each instrument has its own keypad and can also be controlled using an RS232 command set, and/or contact closures (TTL) to start and stop the pump.
