Introduction to the 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; micro 3mm, 2µL; semi-micro 6mm, 5µL) and Prep Cells are available
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.
