Description
The Chromaster 5440 Fluorescence Detector from Hitachi offers superior user experience with a low dwell volume and minimal carry-over — enhancing both chromatography performance and portability. The detector's advanced technology ensures unparalleled sensitivity for a variety of applications, from industrial processes to pharmaceutical analysis. Its modular design and available accessories guarantee versatility and reliability.
Features
High sensitivity with an S/N ratio of 1,200 or higher in water Raman
The detector incorporates low-light loss optics featuring a three-axis layout, Hitachi’s proprietary condensing mirrors, a slit flow cell, and an optimized transmission light monitoring method. This is a high-sensitivity fluorescence detector with an S/N ratio of 1,200 or higher (based on the baseline method) in water Raman.
Automatic wavelength check using a built-in Hg lamp
Similar to the UV detector, the 254 nm bright line from the Hg lamp can be used to perform wavelength checks in the UV region that is often used in HPLC analyses.
Fluorescence detector with a variable slit
The spectrometer slit on the fluorescence side is variable between 15 nm and 30 nm. For high-sensitivity analyses, use the 30 nm slit.
Included Accessories
- AC Adapter
- Data Cable
- UI Pad
