GC-6890 Gas Chromatograph can be used to measure residual solvent for packaging industry or other related industries and detecting institutions. It is the best choice for determination of residual solvent, smell analysis, and solvent purity. 
Professional Technology 
 GC-6890 comes with characteristics of profession, reliability, precision and competitive price, which is equipped with hydrogen flame 
ionization detector (FID). 
 The instrument is controlled by micro-computer and integrated circuit, with big display screen. Functions of keyboard inputting parameters, power failure protection and file storage or inquiry provide a comfortable operating environment. 
 Detectors with control elements utilize plug-and-play (PNP) extension control mode 
 Constant temperature or temperature program can be achieved in this instrument. And preset of chromatographic column chamber could be reached through automatic open-close of its flexible back door. 
 Gas tube is flexible and reliable which extendable for different feeding gases or tests. 
 Sampler system is equipped with packed column, capillary column and other devices to transfer test gases into the system. 
 Instrument is designed with functions of lower pressure for carrier gas tube and protection gas transmission interrupt. 
 High temperature protection is applied so that instrument could stop working and alarm when the temperature of any gas tube exceeds the preset (set at 20°C). 
 1500mV wide range of response signal, with good consistency, could meet analysis requirements of high purity samples. 
 Good performance of chromatographic column box makes it possible to achieve the operation at room temperature+3°C, even when the temperatures of detection and vaporizing chambers are as high 200°C. Instrument comes with good repeatability of temperature program to ensure the retention time consistency of sample components. 
 Special designed operating software and hardware could automatically monitor the whole process, which creates a safe test environment for users. 
 Instrument could be easily connected with chromatography data converter, system or other graphing devices. 
 Professional chromatographic data system provides powerful and intelligent process function to automatically identify the names and quantities (mg/m2) of residual solvents tested samples in accordance with reference data. Instrument is also available for the detection of solvent purity. 
Test Principle 
A gas chromatograph is a separating or analytical instrument for mixture containing various components. It takes the inert gas as mobile phase, and utilizes chromatographic column separation technology. The mixture

injected into the instrument follows the carrier gas into a separation tube known as “column”. Because of different distribution coefficients in the column, distinct components will display different mobile speeds. After certain column, the analyzed components will leave column consecutively into detector where corresponding electrical signals will be generated and taken to chromatography data system. The detection analysis of tested mixture is accomplished.
