In-house construction of a UHPLC system enabling the identification of over 4000 protein groups in a single analysis.
Here, we describe an in-house built ultra-high pressure liquid chromatography (UHPLC) system, with little complexity in design and high separation power combined with convenience in operation. This system enables the use of long columns of 40 cm packed with 1.8 μm particles generating pressures below 1000 bar. Furthermore, the system could be operated at flow rates between 50 and 200 nL min(-1) while maintaining its separation power. Several gradients were optimized ranging from 23 to 458 min...Expand abstract
