Description:
Intelligent Microprocessor control, stable and reliable, precise control
1) HPLC-P600 High Pressure Constant Pump is a kind of intelligent microprocessor reciprocating plunger pump,with functions of high working pressure, low pulse, safe and stable,easy operation and so on. The mechanical components are designed by computer, the main spare parts are produced by the world’s advanced CNC machining center, so it has the characteristics of high precision, good sealing performance of pump, good interchangeability of parts and so on.
2) The plunger rod with floating guide structure, driving cam is made of high strength alloy steel. Adopting the microprocessor control the microstep drive circuit, making the driven pump’s stepper motor running stably, low noise, wide range of speed adjustment. HPLC-600 high pressure constant pump pressure range is 0~42Mpa, the flow rate is from 0.001ml/min to 9.999ml/min. Meet the needs of conventional analysis to micro flow analysis.
Easy to set parameters
In the isocratic analysis of single pump, according to the mentioned words on the HPLCD screen of the instrument, through the 4 function keys to transform various operation modes.And can set the flow rate and pressure limits, continuous working time and pressure unit parameters conveniently.
Parallel double cone flow cell, reduce instrument noise and signal drift.
HPLC-UV600 Ultraviolet detector adopt parallel double cone flow cell, sample pool and reference pool is completely equal. The flow cell which is designed by cone hole, under the condition of the same volume, improves the light energy through the cell, significantly reduced the instrument static noise and signal drift.
More precisely optical system
The optical system adopts the precise positioning structure, so the precision is high and the offset is small. The deuterium lamp holder and the light path system adopt the heat isolation installation technology, which reduces the stability time of the instrument, and reduces the influence of the deuterium lamp heating on the optical path system.
Application
Chemical analysis、poison analysis、environmental analysis、protein food detection、medicine testing、polymer analysis.
