1110 Pump

Inheriting Hiri HPLC The traditional pump is developed for conventional analysis.
Always maintain stable and high performance in daily measurement work, and is your right-hand assistant to analyze your work.

Improve flow rate precision
Hitachi liquid phase pump has always adopted the speed control method to suppress liquid pulses. Primaide PLUS 1110 The pump can monitor pressure fluctuations in real time, set the speed range of the plunger at the optimal time, effectively suppressing liquid pulses.

Improve the reproducibility of gradient analysis retention time
Primaide PLUS 1210 The injection time of the automatic injector is synchronized with the gradient cycle time of the pump, and the retention time reproducibility of gradient analysis is excellent and the analysis accuracy is high.

1210 Automatic sampler

Primaide PLUS 1210 The automatic sampler adopts direct injection method, which is especially suitable for small and expensive samples.

Direct injection method to save sample volume and improve analysis speed
The direct injection method is adopted. The injection needle is part of the flow path. All samples sucked into the injection needle can be injected into the flow path, reducing sample consumption and giving full play to the advantages in the determination of small and expensive samples.
Compared with the injection method using quantitative rings, the injection steps are simple, the injection cycle can be shortened to half, which improves the measurement speed and helps high-throughput analysis.

High-precision analysis by improving reproducibility
The syringe driving part used to control the sample injection volume adopts a high-precision stepping motor, and the injection time is synchronized with the pump gradient cycle time, improving the reproducibility of the injection volume and the reliability of the analysis results.

Injection volume reproducibility data

The new dark window is adopted, with low light transmittance and is compatible with the analysis of light-sensitive samples to ensure good reproducibility of data.

1315 Column thermostat

Primaide PLUS 1315 The column thermostat is equipped with preheating function to achieve sharp peak shape, giving full play to the performance of the chromatographic column.
Refrigeration function is standard.

Optimize preheating method to achieve sharp peak shape
Through the preheating module with excellent thermal efficiency, the symmetry and sharpness of the chromatographic peaks are improved, and the stability of the analysis results is not affected by ambient temperature changes. The column part adopts air circulation heating to facilitate the replacement of the column.

Standard cooling function
Temperature control range [Ambient temperature-15 ℃（Minimum 4 ℃）】To [ambient temperature +50℃（Up to 65 ℃）】。

A variety of valves are available to meet more needs
