This document introduces the performance characteristics of the Agilent 1200 Infinity Series Variable Wavelength Detectors, including faster results, improved sensitivity and absolute data security. The series detectors have two versions: Agilent 1260 Infinity VWD (G1314F) and Agilent 1290 Infinity VWD (G1314E), the latter with high sampling rates for ultra-fast HPLC and UHPLC. These detectors offer the following features and benefits: Higher sampling rates up to 160 Hz for ultra-fast HPLC (Agilent 1290 Infinity VWD) or up to 80 Hz (Agilent 1260 Infinity VWD); Data Recovery Card (DRC) provides for unique 'data-never-lost insurance' (Agilent 1290 Infinity VWD); Deuterium lamp for highest intensity and lowest detection limit over a wavelength range of 190 to 600 nm; Optional flow-cell cartridges such as standard (10 mm path length/14 µL volume), high pressure (10 mm/14 µL), micro (3 mm/2 µL) and semi-micro (6 mm/5 µL) are available and can be deployed according to application needs; Easy front access to flow cell and lamp for fast replacement; Flow cell and lamp with RFID tag for safe identification; Lamp information, including part number, serial number, production date, number of ignitions, total burn time; Cell information, including part number, serial number, production date, nominal path length, volume, maximum pressure; Built-in electr.
