LC4000 enhanced performance liquid chromatography
Features
LC-4000 high-voltage constant-current pump features l LC-4000 dual-piston high-pressure pump is a constant series reciprocating Heng
Flow pump, high flow accuracy; l subdivision stepping motor control technology allows the motor to run at low speed
Smooth and accurate, to improve the accuracy and repeatability of analytical results at low flow rates, effectively ensuring the high-pressure gradient system
Under low flow systems and mobile phase composition stability;
The key component installation guide l floating plunger rod, plunger rod and a selection of high-quality seals, etc.
To ensure that the constant high pressure infusion pump long running stability and durability;
l mobile phase compressibility factor correction and flow calibration accuracy dual function, depending on the solvent system differences
Error compensation in flow velocity within ± 15% range, ensuring a high flow accuracy;
l via RS-485 chromatography workstation external control can be easily obtained with high accuracy two yuan high-pressure gradient
Of the system, while the mobile phase velocity gradient can be achieved to meet the various requirements of production and research;
l Real-time pressure monitoring display, high pressure limit, low limit alarm function to ensure the safety of equipment used;
l large flow flushing solvent substitution function, reducing the solvent displacement time, improve work efficiency;
l with an OLED display module, friendly interface, easy and flexible operation.

LC-4000 variable wavelength UV / visible spectrophotometric detector
Instrument features
l advanced optical cell design;
Detector optical system into the new design ideas. As we know, the UV detector principle is
Based on the Lambert - Beer law, so we focus on the improvement of the optical path above the road and so the sample is located
The reference light path of light for maximum battery power. SEV UV501 detector is designed with today's most advanced technology
Surgery for the pilot, through digital data processing and control, so that baseline noise and drift down to a new
Limit. As a result of the digital output function, the detector can be connected to a computer via serial port directly
Without the need for any of the data acquisition unit.
Wherein, I1 is the sample path light intensity, I0 is the intensity of the reference light path, ε is the molar extinction coefficient, L is the flow
Cell path.
