简单介绍
The chromatograph based high performance HPLC new design. The instrument (basic type) consists of three parts: high pressure infusion pump, injection separation system and ultraviolet / visible light
产品描述
Characteristic：
Microcomputer type double pump head type high pressure pump with complementary -, self checking system, the pump body is made of stainless steel materials or polymer materials.
The UV / visible detector using grating system, special micro flow cell, can change the wavelength analysis settings. With a five inch color LCD screen as a terminal display device, real-time observation of test results and the spectrum and all kinds of operation parameters as data transferred to the window.
Injector - instrument selection of international universal standard six valve connecting pipe made of stainless steel pipe or PEEK Catheter; column using domestic standard C Eighteen Column. The apparatus is provided with a column thermotank, column box at the same time be able to install two 70mm ~ 250mm Column length. The analysis system uses a catheter with a sealing washer, nut and universal joints are the same size, with imported instruments and accessories sharing.
The instrument signal output, data processor interface configuration (1AU/V ) and recorder interface (10mv/FS ) and with the RS232 Output interface can realize bidirectional communication control and chromatography workstation.
