Description

DAD400 detector

The detector belongs to a diode array (DAD) detector, which can detect 4 wavelengths at the same time, and also can scan DAD. In the process of liquid chromatography analysis, due to the difference in the optimal absorption wavelength of different compounds in the same sample, detection at the same wavelength will lead to quantitative deviation, so simultaneous multi-band detection is conducive to the analysis and quantification of sample purity.

The detector can be used in flash and preparation instruments.

This DAD detector has the following advantages:

● Simultaneous four-wavelength detection.

● The wavelength is set to 200-400nm in increments of 1nm.

● Full wavelength online scanning.

● The light source is counted by a built-in timer.

● The flow cell is easy to replace.

● The power supply range is relatively wide (90-264V).

● It can be controlled manually or by computer.

● The signal can be output in analog or electronic form.

● Easy to diagnose and maintain.
