Through chromatographic workstationsGUIController or control panel, can set any flow rate (maximum)9.999mL/min）,At any time (maximum)30min）Realize automatic drainage.

Automatic sampling system
·Excellent injection accuracy
By relying on the configured high-precision injector drive unit, excellent injection accuracy can be achieved.
·Extremely low sample residue
Hitachi has greatly reduced the dead volume caused by residual in the flow path of the automatic sampler, and adopted a pump for cleaning the outer wall to achieve extremely low sample residue.
·Special online degassing device for automatic sampler
Built in, does not take up additional space
·Automatic sampler with temperature control device
Controllable temperature range: (room temperature)-21℃）To (room temperature)+25℃）A wider temperature control range, expanding the application field of the instrument, preventing the crystallization of compounds in the sample bottle to ensure the stability of the sample.

Column constant temperature system
·Standard preheating function
The standard preheating module is based on Peltier heating/The cooling control function greatly improves the symmetry and sharpness of the peak shape.
·A wider temperature control range
The temperature control range of the column temperature box is (room temperature)-15℃）To (room temperature)+60℃）It can meet various application needs.
·Large column temperature box
Easy to accommodate with protective pillars300mmAnalysis column, internal dimensions wide375mmUp and down high114mm, Open itLFont shaped door, convenient for connecting and placing chromatography columns, can accommodate3root300mmChromatographic column.
·Chromatographic Column Management System
adoptchromasterThe chromatographic column management system can manage log information for chromatographic columns and protection, regardless of which chromatographic column manufacturer produces them. The log information of the chromatographic column is saved inIDIn the tag, log information can be obtained through the connector installed on the column temperature box or the computer'sUSBInterface for reading and writing,IDLabels can be reused repeatedly.

detecting system
· CM-5410/5420Ultraviolet/UV Visible Detector
Dual wavelength high-sensitivity detection, especially for the examination of drug-related substances. The dual wavelength detection function can be achieved under shorter data acquisition intervals, and each wavelength data acquisition interval can be set as800msEven400msIt can obtain better and sharper peak shapes.
· CM-5430Diode array detector
Higher qualitative analysis ability
Wide wavelength range（190～900nm）And hyperspectral resolution (with1024bitDiodes)chromasterThe diode array detector is committed to creating the world's highest level of high-resolution analysis.
Lower noise
The noise level of the diode array detector is comparable to that of the ultraviolet detector, supporting high-sensitivity analysis.
Lower drift
Adopting a fan with adjustable air volume and a specific cover plate on the splitter greatly reduces the impact of temperature changes around the optical system, further reducing drift.
·Constant temperature circulation pool
The constant temperature flow cell minimizes the impact of room temperature changes, making the detector baseline more stable and the data more reliable.
