Details LC-3000 liquid chromatograph and other type of the system: Instrument Description LC-3000 analytical chromatography - high accuracy, fast preparation and high efficiency. LC-3000 in various fields laboratory, semi-preparative chromatography, chromatography, countercurrent chromatography made extensive use of the experience and technology for new technology development, and constantly enrich the various functions of laboratory analysis and production of purified preparation required . Instrument Description SPD-3000 UV detector and sample characteristics of the reference energy intensity L uses dual holographic grating technology. Automatic display, automatic memory timely diagnose and light machine running time, in full compliance with GLP, 高标准 certification application precision photodiode design 15 kinds of phthalates, linear scope. Through a unique design holmium glass tank full wavelength scanning, easy to prepare wavelength calibration. Phthalates low noise, low drift, excellent signal to noise ratio. Universal sample cell design for easy replacement between the trace and the constant pool. Convenient light intensity gain factor correction function set deuterium lamp replacement simple, fast, can be used without correction. Through a unique design holmium glass tank full wavelength scanning, easy to prepare wavelength calibration technical characteristics LC-3000 is designed cam curve and a specific structure, a difference of 180 ° cam advance the plunger rod in the motor drive, completion of the infusion process. Main and auxiliary cam has the same base radius, the main lift cam 10, cam lift pay for 7.125; the plunger steady stream output during operation. Designed a special damper buffer system with main and auxiliary cam match, you can get a very low pulse output stream type phthalates 8p, to overcome the traditional buffer system failure rate, inadequate and poor results. Special design and synergies cam and damping effectively reduces the flow pulsation of compression due to differences in the composition of the different factors which led to the traffic caused by the differences can be automatically adjusted phthalate esters, avoiding the use of dual pressure sensor than high cost. Dual buffer system protection valve and pressure combination, it is possible to effectively prevent each infusion process reflux phenomenon. Traditional plunger propulsion system for a new design, and even improve the traditional lever and plunger rod integral structure for sub-structure to ensure that the plunger rod back into place in a shorter time, pulsation phenomenon due to the pressure difference caused by the reduced to a minimum, get a very stable low pulsation flow and the mechanical noise is also extremely low. The new design uses a patented motor control technology to improve the low frequency operation characteristics, reduced pulsation phenomenon, expanding the infusion pump flow range, the flow range up to six orders of magnitude (flow range from 0.1ul / min-10.000ul / min ). These special structural design, so that the two plunger pump head alternately process produces a very small amount of liquid corresponding pressure rebound, avoid the use of full vacuum injection method to bring produce bubbles and holes and other issues, without additional specific components greatly simplifies the design, reduces costs, while increasing the stability of the pump phthalates 8p, testing equipment (certified), phthalates are provided by Shenzhen Huayi Technology Co., Ltd. universal.
