Hitachi Primaide PM1110 HPLC Pump Isocratic Module

High-Performance Liquid Chromatograph Primaide

Hitachi Primaide™ PM1110 isocratic pump, programmable

The Primaide1110 Pump has been developed for reliable analysis and shares characteristics with Hitachi's existing HPLC pump models. Its consistently high level of performance provides users with strong support in everyday analysis.

Improvement of flow rate stability
For pulse compensation, a proprietary real-time feedback method has been developed for Hitachi’s pumps. Not only has the pulse has been significantly reduced, but the Primaide1110 Pump estimates pressure fluctuations and employs the optimal timing to set the plunger speed interval.

Improvement of retention time reproducibility
For gradient analysis, injection by the Primaide1210 Autosampler is synchronized with the movements of the pump. This ensures a highly-reproducible retention time, and guarantees precise analysis.

Built-in optional units inside pump
Both the degasser and gradient unit can be mounted inside the pump. A built-in degasser minimizes the tubing volume, and yields a more compact system by eliminating the need for additional modules. The gradient unit is capable of mixing 4 solvents via its solenoid valves. The placement of the mixer in a high-pressure compartment enables high-precision, stable mixing, even with a single pump.
