The Agilent 1220 Infinity Gradient LC is a liquid chromatography (LC) system for routine standard analysis. Due to its extraordinary pressure range up to 600 bar, the system can also perform UHPLC applications. It is an integrated LC system consisting of a binary low pressure mixing (‘dual gradient’) pump, autosampler, column compartment and variable wavelength detector (VWD). The dual gradient pump has a flow range from 0.2 up to10 mL/min (5 mL at 600 bar, 10 mL at 200 bar), low pressure mixing and an integrated degasser. The VWD detector features 80 Hz data acquisition rate and a wavelength range from 190 nm up to 600 nm. The autosampler can operate up to 600 bar, with an injection volume range from 0.1 to 100 μL and a capacity of 100 2 mL vials. The column oven holds one 25 cm column and the maximum temperature is 60 °C.

The typical performance of the Agilent 1220 Infinity LC includes high precision of retention time and area, precise gradient formation, and excellent signal-to-noise ratio.  Capable of processing about 100 samples per day, the Agilent Infinity II 1220 LC reliably tests 11 of the major cannabinoids and is ideal for cannabis testing labs performing routine testing.
