Like the 1100 series the 1200 model is a workhorse for the demanding needs of any QA/QC lab for the most advanced analytical and method development applications.

The heart of any HPLC system is the pump. The 1200 quaternary pump model G1311 is designed for routine method development and high throughput gradient applications for greatest flexibility with multisolvent gradients by accessing up to 4 solvents. Accurate flow rates coupled with low pulsation = awesome 

The G1315 DAD detector gives you Spectral information from 190 to 950 nm The dual-lamp design and the temperature control of the Agilent 1200 Series diode array detectors ensure outstanding sensitivity. Photodiode arrays with 1024 elements, programmable slit width (1, 2, 4, 8, 16 nm) and the selection of nine different flow cells enable optimization of resolution, linearity and will NOT cramp your analytical capability. 

The 1200 series autosampler typical repeatability and LACK of carryover is astronomically outstanding. Superior injection precision and lowest carryover makes your runs trustworthy day in day out. The 1200 autosamplers provide for precision levels of < 0.5 % RSD over an injection volume range from 0.01 μL to 2000 μL. The unique flow-through design, combined with the external needle wash and optional multiple wash solvents, virtually eliminates carryover, even for highly adsorptive compounds.
