LC-4000 Series HPLC
The LC-4000 Series is the latest in a long history of innovative HPLC systems developed by JASCO, reaching all the way back to the start of commercial HPLC in the early 1970s. The concept of the integrated LC-4000 series HPLC provides key separation platforms at 50MPa, 70MPa, and 130MPa which correspond to conventional HPLC, the increasingly popular Rapid Analysis (RHPLC), and sub 2um UHPLC respectively.
The LC-4000 Series HPLC has key separation platforms at 50 MPa for conventional HPLC (3, 5, and 10 μm columns), 70 MPa for RHPLC (intermediate columns such as 2 to 3 μm and ‘coreshell‘), and 130 MP for UHPLC (sub 2 μm).

Advances in HPLC Solvent Delivery
For more than three decades JASCO analytical HPLC pumps have employed an asymmetric twin-piston solvent delivery system SSQD (Slow Suction, Quick Delivery) which provides significantly better flow and pressure characteristics than conventional twin-piston reciprocating designs. SSQD Technology offers the highest stability ‘compensated’ solvent delivery used in the PU-4180/85 RHPLC and PU-4280/85 UHPLC pump models, this makes it an excellent choice for detectors that are affected by flow pulsation like ECD, RI, and mass spec.
