I.Product Introduction
The chromatograph system newly designed with high-performance HPLC. Instrument (base model) is formed by the high-pressure infusion pump, injector separation system, UV / VIS detector .
II.Features:
1. Adopts microcomputer dual-head pump complementary pressure infusion pump, with self-checking system, pump made of stainless steel or polymer materials.
2. UV / VIS detector using grating system, a special micro flow cell, setting the time-varying wavelength analysis. With five-inch color LCD screen as a terminal display device, could observe the test results in real time , as the transferred windows for all spectral and operational data .
3. The instrument injector is the international universal standard six-way valve, connecting pipe is stainless steel tube or PEEK conduit; separation column using domestic standard C18 column. The instrument has column thermostat, in-oven can also install two 70mm ~ 250mm long column tube. Analysis system uses a catheter with sealing washer, nut connectors, are identical with the internationally accepted standard,could share with the imported equipment accessories .
4. The instrument's signal outputconfigured the data processor interface (1AU / V) and recorders Interface (10mv/FS) and offers RS232 output interface enables double direction communication with the chromatography workstation .
III.Technical indicators:
1. Column thermostat: Temperature range: room temperature + 10 ℃ ~ 89 ℃ (increment 1 ℃) temperature stability error: not more than 0.5 ℃
2. High pressure infusion pump: Flow rate setting range: 0.1ml/min ~ 9.90ml/min flow stability error: not more than 2% maximum output pressure: Metal system: 40MPa; nonmetal system: 25MPa
