Agilent InfinityLab LC Series Diode Array Detectors User Manual 10

1 Introduction

Overview of the Module

The detector is designed for highest optical performance, GLP compliance and

easy maintenance. It includes the following features:

• Maximum of 120 Hz (G7117A/G7117C) or 240 Hz (G7117B) data acquisition

rate.

• Higher sensitivity for conventional LC as well as ultra fast applications by

using next generation optical design.

• Increased sensitivity with 60 mm Max-Light cartridge flow cell.

• Optimized cell geometry for less peak dispersion for narrow bore applications.

• Max-Light cartridge flow cells for standard applications are available, see

“Max-Light Cartridge Flow Cell” on page 15.

• More reliable and robust peak integration process (automated) due to less

baseline noise/drift/refractive index and thermal effects especially under ultra

fast gradient conditions.

• RFID tracking technology is used for the UV-lamp and the Max-Light cartridge

flow cells.

• Multiple wavelength and full spectral detection at 120 Hz

(G7117A/G7117C)/240 Hz (G7117B) sampling rate, keeping up with the

analysis speed of ultra-fast LC.

• Programmable 1 – 8 nm slit (G7117B) or fixed 4 nm slit (G7117A/C) for rapid

optimization of sensitivity, linearity and spectral resolution provides optimum

incident light conditions.

• Improved Electronic temperature control (ETC) provides maximum baseline

stability and practical sensitivity under fluctuating ambient temperature and

humidity conditions.

• Additional diagnostic signals for temperature and lamp voltage monitoring.

• Easy exchange of flow cell by cartridge design.
