This instrument adopts the technology of digital communication, which enables it to fully control all the operations of every unit of the LC-100 HPLC system and accomplish the isocratic analysis, high-pressure gradient analysis, wavelength scanning and spectrum Scanning etc.
System is under fully automated digital intelligent computer control
In-parallel connected pumps with reciprocating double plungers improve the stability and dependability and prolong the service life.
Its appearance is novel, and its operation is quite convenient and simply and fully incarnates the design of humanization.
Every performance index is excellent and is competent to match popular fellow products abroad.
Optical path system adopts a precise positioning structure and the technology of heat insulation installation, which guarantees high precision, small excursion and short period for stabilization.
Reciprocating pump with a parallel connection of double plungers and an intelligent control of a microprocessor has higher operating pressure, smaller pulsation, stable performance, convenient operation and some other features, etc. Through alternating the double plungers to perfuse, the service life of the piston rod and that of the leather packing collar are twice longer than those of common pumps with connection in series.
All the mechanical components of the pumps adopt the computer aided design. Every key spare part is made in advanced digital control machining centers of the world. So, on the basis of such extraordinary machining accuracy and every set of pump after strict pressure tests, we can guarantee that our pumps will never have any possibility of leakage! Please use it free from care.
The product has process monitoring function. The microprocessor furnished has the flow of the pump under a real-time control and provides an actual monitoring of the perfusion pressure. Once the pressure exceeds the limit, the pump will give an alarm and automatically stop operating.
Advanced Structural Design: The whole structure adopts a modular design and, including its mechanical parts and circuit parts can be independently assembled/ disassembled, so it is very conveniently for troubleshooting and maintenance.
The product adopts the micro drive circuit under a microprocessor control, which gets the stepper motor that drives the pump runs steadily, reduces its noise and enlarges the allowable range of speed regulation. So the product can satisfy the requirements of both the routine analysis and the microanalysis of flow well.
It has the function of process monitoring. The microprocessor performs a real-time control of flow and monitors the actual perfusion pressure constantly. In case of exceeding the pressure limit, it will give an alarm and stopping the pump’s operation automatically.

UV100 UV Detector
With its pioneering digital switch system, the detector directly outputs digital signal to the WS100 workstation, which avoids the signal distortion and interference that common UV detectors may bring about during their multiple analog-to-digital conversion of chromatograph signal.
Its outstanding flow cell design, the detector breaks through and improves every technical index of UV detectors. (Patented Product)
The optical path system adopts a precise positioning structure with high accuracy and small deviation. The deuterium lamp and the optical path system adopt the heat insulation technology, which shortens the stabilizing hours and minimizes the negative effect that the deuterium lamp brings to the optical path system.
The preamplifier adopts an instrument amplifier with high impedance but low excursion and an A/D switch with high definition. Under common analysis circumstances, its dynamic range can amount to 106, which ensures the precision of logarithmic calculation.

WSl00 chromatogram workstation software realizes the fully automated integration of UV detector and high-pressure constant flow pump, and has powerful control function and simple, convenient and swift operation.
The software has adopted a fully automated digital control system, which makes the workflow become easier and increases the accuracy of operation. The software mainly consists of two major function modules, namely LC-100 PLUS control module and the chromatogram data processing module.
Its strong control function enables the instrument control every unit of LC-100 PLUS at the same time under a graphic interface, perform the isocratic and gradient analysis, wavelength scanning, chromatograph scanning and switching event relay, etc, display the flow quantity curves, wavelength scanning curves and so on of several sets of pumps at the same time.
Six kinds of quantitative algorithmic methods: normalization, revised normalization, revised normalization with factor of proportionality, internal standard method, and external standard method and index calculation.
Calibrating Operation: Realize the calibration of standard samples with multiple concentrations and set up a calibration curve of sample concentration and peak area.
Flexible Peak Identification and Disposal: identify and dispose the chromatograph peak through setting the peak disposal parameters and the timing programmer, or dispose manually.
Spectrogram Tidy-Up: spectrogram, enacted quantitative computing method, peak disposal parameter and peak identification, etc., can be saved in any file titled by the user.
