Pump System

Higher precision, Lower pulsation and Excellent stability

The four element pump system achieves high-frequency mixing of the gradient system, reduces the generation of solvent mixing bubbles, reduces infusion pulsation, and ensures infusion accuracy and stability.

HFM high frequency hybrid mode

By increasing the switching frequency of proportional valve, the mixing accuracy of mobile phase is improved.

The sufficient mixing of solvent can be ensured without large volume mixer, which greatly reduces the system delay volume and baseline noise of the system.

Special curve cam design

The special curve cam is used to drive the plunger to make the infusion more stable and lower pulsation.

High speed feedback and real-time control

Through real-time monitoring the pressure of the system, adjusting the motor speed, and equipped with special curve cam transmission, the infusion pulsation can be further reduced while ensuring the stability of flow.

Cascade inlet and outlet valve core design

The two-stage series valve core of the inlet and outlet valve ensures the stability of infusion and reduces the pulsation of the pump system.

Rich options and easy maintenance

The sealing ring of the pump, the sealing ring of the cleaning device, the one-way valve and the plunger rod can be directly replaced in front of the pump, which is convenient for maintenance. The degassing device and gradient unit are built-in to realize a simple and tight paint appearance.

Automatic Sampler System

Lower residue, Higher precision and Excellent reproducibility.

High injection reproducibility

The direct injection method combined with the improved design of a new high-precision injection driving unit ensures the accuracy and repeatability of the injection.

FTN injection method
Surf style needle outer wall cleaning
Needle washing solution not to be reused

	Low sample residue Reduce sample waste, reduce sample residue and improve injection reproducibility; Improving the injection speed is beneficial for high-throughput sample analysis; The optimized injection system cleaning method further reduces sample residue.
Sampler with thermo rack (optional) The system uses Peltier temperature control module to accurately stabilize the temperature of the sampler at the set value and ensure the stability of temperature sensitive samples.
For temperature sensitive samples, the sample analysis is carried out without the temperature control of the injection system. The increase of external temperature will lead to the generation of impurities, and the impurities will gradually increase and become larger.
For the same sample, the sample was analyzed at 4℃ in the sampling system, and the analysis results did not change with the passage of time.
Humanized sample rack design The inner part of the instrument is designed to prevent condensation and improve the service life of the instrument.

Column Oven

More accurate temperature control accuracy; Wider temperature control range; More flexible column management;

The column temperature box adopts a Peltier temperature control unit and a specially designed preheating function to ensure sharp, symmetrical, and reproducible chromatographic peaks.

Peltier temperature control mode

Capable of simultaneously heating and cooling, providing a wider temperature control range.

Mobile phase preheating function

The mobile phase is preheated before entering the column to reduce the interference to the temperature environment in the column;

The air inside the column oven always circulates to ensure the constant ambient temperature around the column;

Ensure that the internal temperature of the chromatographic column is constant during the experiment.

Liquid Chromatograph Air circulation mode

Optional valve

Column switching valve: three chromatographic columns can be placed at the same time. Through the three column switching valve, the flexible switching between chromatographic columns can be realized, which is convenient for method development and column screening.

Two position six way valve: it can meet the experimental needs of a variety of chromatographic methods, such as online sample processing, online enrichment, two-dimensional chromatography, etc.

A Variety of Detectors with Excellent Performance

A variety of detectors can be selected to meet the different needs of users.

UV Detector

Adopting high-quality optical units and optimized optical path design, it can provide higher sensitivity and meet the analysis of trace and trace samples.

DAD

The sensitivity of DAD detector reaches the level of UV detector which can meet the needs of high sensitivity analysis and purity analysis at the same time.
