10 Agilent 1200 Infinity Series DAD User Manual

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 160 Hz (G4212A) or 80 Hz (G4212B) 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 and bio-inert applications are

available.

• 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 160 Hz (G4212A)/80 Hz

(G4212B) sampling rate, keeping up with the analysis speed of ultra-fast

LC.

• Programmable 1 – 8 nm slit (G4212A) or fixed 4 nm slit (G4212B) 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.
