UV Detector LCD 2070.1 analytical
UV detector LCD 2070.1
is small simple unit for use in analytical liquid chromatography applications based on measurement of absorption of UV radiation of 254nm. The unit is easy for operating, reference and sample signal is available for detector diagnostics and lamp live reading.
The detector is equipped with two interference filters 254 nm to reduce the others spectral lines of mercury lamp.
Very interesting are the small dimensions of unit.
There is possible to use cell:
Analytical cell HPLC 08
Specification
| Wavelength | 254 nm |
| Light source | low pressure mercury lamp |
