Gilson 171/172 Diode Array Detectors

Gilson 171/172 Diode Array Detectors

 


With a remote flow cell, the power of the detector is located directly at the outlet of the column, which yields virtually no peak broadening. An interchangeable flow cell design allows for both 171 and 172 Detectors to accommodate analytical and semi-preparative to preparative applications.
