RUNJIE GC-L6 Gas Chromatograph is an analytical instrument with good performance and simple operation interface. It is widely used in Petrochemicals, Fine Chemicals, Coal Mining, Pesticides, Research Institutes, Universities & colleges, environment monitoring and other industries.
1. Adopt full microcomputer control system, large-screen LED Chinese display, highly integrated electronic circuit, Chinese keyboard operation, easy to set parameters and operate. 2. The column box has a compact structure, intelligent dual-channel rear door design, and fast cooling speed (only 8 minutes from 280 ° C to 50 ° C), which can be stably controlled at 5 ° C above room temperature. 3. It can be equipped with multiple Vaporizers at the same time (two Packed column Vaporizers and one capillary tubing Vaporizer, or two capillary tubing Vaporizers), and can be expanded from a single amplifier to a dual amplifier, and up to three Detectors (such as FID, TCD, FPD) can be installed simultaneously to achieve series and parallel operation of Detectors. 4. Capillary column of different specifications can be selected, and the reasonable design of capillary tubing injection system (split/non-split injection, diaphragm purge and tail blowing system) makes the Extra column effect small, the column efficiency is high, the peak shape is good, the Basis Weight result is accurate and the repeability is good. 5. Modular design, simple installation and easy maintenance; the new FID detection limit is lower, and the nozzle and ion collector are easy to disassemble and clean. 6. The gas circuit adopts the dual design of first stabilizing and then steady flow, the adjustment mode is stable, with High Accuracy and high reliability, with air break/air leakage protection and prompt function, and can automatically cut off the TCD bridge current to protect the rhenium tungsten wire. 7. With a six-way temperature control system, including column chamber, Vaporizer, detection chamber, conversion furnace, and external control events. 8. With a fifth-order linear temperature programming function, it can satisfy multi-component sample analysis. 9. It has power-down protection, over-temperature protection, and power-on self-test functions.
The Gas Chromatograph is based on the principle of chromatograph separation. After the sample is vaporized by the Vaporizer, it is brought into the Chromatography Column by the Developing solvent. Due to the different distribution or adsorption coefficients of each component in the sample between the Stationary phase and the Mobile phase carrier gas (Developing solvent) in the Chromatography Column, under the impetus of the Developing solvent, each component is repeatedly allocated between the two phases, so that each component is separated in the Chromatography Column and enters the Detector in turn. Detector converts the concentration or mass signal of each component into an electrical signal, which is processed by the data processing system to obtain the Chromatographic peak, so as to realize the qualitative and quantitative analysis of the sample.

1. Check the air source and power connection before starting to ensure good sealing of the air path. 2. Open the carrier gas source, adjust the pressure reducing valve to the required pressure, and set or adjust the flow of Developing solvent through the instrument panel. 3. Turn on the power supply of the instrument, and set or call the parameters of the analysis method through the Chinese keyboard, including the temperature of each temperature control area (column box, Sample injector, Detector), and the temperature program. 4. Start the heating and wait until the temperature of each temperature control zone reaches the set value and is stable (Baseline is stable). 5. According to the sample and Chromatography Column type, select the appropriate injection method (e.g. Packed column injection, capillary tubing shunt/unshunt injection), and use Microsyringe injection. 6. Start the data collection system to record Chromatographic peaks. 7. After the analysis, perform the procedure to cool down or naturally chill down as needed. 8. Turn off the Detector (such as the hydrogen and air of FID) and the heating system. After the column temperature drops to close to room temperature, turn off the Developing solvent and the total power supply of the instrument.
• The instrument should be installed on a stable table without corrosive gas, well ventilated, away from fire sources and strong electromagnetic interference. • Developing solvents (e.g. nitrogen, hydrogen, helium) and auxiliary gases (e.g. hydrogen, air) must be tightly connected to prevent leakage. • When booting, the Developing solvent must be turned on first, and then heated by electricity to prevent the Chromatography Column and Detector (such as TCD's rhenium tungsten wire) from burning when no Developing solvent passes through. When shutting down, turn off the heating system first, and then turn off the Developing solvent after the temperature drops. • Correctly select and install the Chromatography Column according to the analysis requirements to ensure the sealing of the column joint. Capillary column installation should pay attention to the position of the column head and the shunt/tail blowing flow settings. • The injection action should be rapid and consistent to avoid sample discrimination and peak tailing. Regularly replace the injection pad and liner. • Before ignition of a Detector (e.g. FID), make sure that the hydrogen and air flow rates are set correctly and stable. • When performing programmed temperature analysis, the final temperature set must not exceed the maximum operating temperature of the Chromatography Column and Stationary phase. • Perform regular instrument maintenance, such as cleaning the injection port, Detector (ionization chamber, collector), and checking and replacing aging or contaminated Chromatography Columns. • Pay attention to observe the status of the instrument. In case of abnormal alarms (such as over-temperature or air leakage), you should immediately find the cause and troubleshoot. Operators should be trained and familiar with instrument operating procedures and safety knowledge.
