FIG. 5 function key diagram of qt-330 thermostat."SET" sets the key to enter the parameter setting state.Increase the key (the length is 10 seconds to start the setting)"Drop" data reduces keys.The data shift key.In high performance liquid chromatography (HPLC) analysis system, accurate and stable control of the temperature of chromatographic column, can effectively improve the column efficiency, improve the spectrum peak separating degree, shorten the retention time, lower column back pressure, so as to ensure the accuracy of the analysis results of sample and repeatability.QT series of chromatographic column constant temperature box adopts imported temperature controller and sensor, intelligent self-tuning PID, ceiling overtemperature alarm, automatic power off function, system temperature control of high precision and convenient operation.I. structural characteristics and performance indicators.QT series chromatographic column thermostat is an integral type of temperature controller and heating box in the same chassis. It can be installed vertically or horizontally.* flexible placement: integrated design that can be placed and laid down.* precise temperature control and display: microprocessor thermostat four double digital setting and display, can make the temperature control accuracy is + / - 0.1℃.* convenient observation: the lower part of the heating chamber is provided with a glass window that allows you to easily observe the work of the chromatographic column from the outside of the heating chamber.* safety leakproof design: the bottom of the heating chamber is provided with a receiving box, which can prevent the leakage of the liquid from spreading further when placed.* smooth pipeline channel: the inlet and outlet end of theheating cavity is smooth transition, so as to ensure the smooth passage of the pipeline.
Specification and performance parameters of chromatographic column thermostat.
