UV detector LCD 2070
is small simple unit for use in preparative and flash 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 an interference filter 254 nm to reduce the others spectral lines of mercury lamp.
Very interesting are the small dimensions of unit.
There is possible to use two type of cells:
Preparative cell PLCC 09 for tubing with OD = 1/16"
Preparative cell PLCC 11 for tubing with OD = 1/8"
Important notice: Output signal of the detector is directly proportional to the optical path of the cell. Since the optical paths of cells may be changed, noise and drift levels are referred to the optical path of 10 mm, corresponding to the AU definition.
