1 Introduction to the Variable Wavelength Detector

Introduction to the Detector

The Agilent variable wavelength detectors described in this manual are designed

for highest optical performance, GLP compliance and easy maintenance with:

•higher data rate up to 120 Hz (G7114A) or 240 Hz for ultra-fast-HPLC

(G7114B),

•deuterium lamp for highest intensity and lowest detection limit over a

wavelength range of 190 to 600 nm,

•optional flow-cell cartridges (standard 10 mm, 14 µL; high pressure 10 mm,

14µL;micro3mm,2µL;semi-micro6mm,5µL)andPrepCellsareavailable

and can be used depending on the application needs (other types may be

introduced later),

•Dual wavelength mode, see “Dual-Wavelength Mode” on page 18.

•easy front access to lamp and flow cell for fast replacement,

•electronic identification of flow cell and lamp with RFID (Radio Frequency

Identification) tag for unambiguous identification,

•lamp information: part number, serial number, production date, ignitions,

burn time

•cell information: part number, serial number, production date, nominal

path length, volume, maximum pressure

•built-in electronic temperature control (ETC) for improved baseline stability,

and

•built-in holmium oxide filter for fast wavelength accuracy verification.
