Hitachi Chromaster 5440 Fluorescence Detector
Chromaster 5440 Fluorescence Detector
Please contact our Sales Team with your laboratory requirements and specifications including PC equipment and Software. Uvison service contracts are also available - please see our Engineering section for further information - https://uvison.com/engineering |
This detector is available in the following specifications - please specify when ordering
- Chromaster HPLC 5440 fluorescence detector
- Chromaster HPLC 5440 standalone flourescence detector including UI pad, analogue output, detector signal cable and power unit
FEATURES
High sensitivity with an S/N ratio of 900 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 900 or higher (based on the baseline method) in water Raman.
Thermostat flow cell (optional)
Thermostat controlled flow cell that minimize the influence of ambient temperature changes is available. You can use the flow cells when you need to perform measurements at a fixed, stable sensitivity.
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.
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.
OPTIONAL ACCESSORIES
Please specify when ordering
- Chromaster HPLC user interface keypad. Mounting parts included
- Chromaster HPLC thermostat flow cell. Thermostat flow cell control unit for 5440 fluorescence detectors is also required
- Chromaster HPLC thermostat flow cell control unit. For use with thermostat flow cell for 5440 fluorescence detectors
- Chromaster HPLC 1-channel analogue signal output unit
