GC8120N Gas chromatography enable to install 2 electron capture devices, 2 flame emission photography and 2 ambipolar capillary columns at same time. Satisfy all the needs in pesticide residue testing area. The “Grob” with temporary anti-distributary sampling port and PTV large scale sampling device dramatically improve the sensibility, and effectively perfect the lower limit of pesticide residue’s testing accuracy. It applies with extra auto sampling device which with pre and post sample cleaning, bubble wiping, speed and slow sampling etc, simple and smooth the operation.
Main capacity feature:
Temperature control system with LCD led display enable to control temperature range (+ 8℃-400℃, high accuracy excel±1℃)of column compartment, TCD room, ionization room, vaporize chamber, auxiliary room 1, 2, etc 6 heating zones. This dresses the column compartment with the capacity of constant temperature control, 5 grades temperature program control and back door fast cool down; enable to implement approximate room temperature operation.

Enable to install 2 sampling ports, 4 detectors, 2 suits of capillary column.
Specific capillary column sampler: independent carrier gas circuit system, make-up gas circuit, gas circuit with septum cleaning and distributary flow pass with back pressure valve control. distributary ratio correcting, it is effective to less column flux; back pressure valve control largely decreases the distributary disproportion effects from column pressure fluctuation; make-up gas system guarantees peak shape and high sensibility for best operation; gas circuit with septum cleaning function corrects ghost peak. suitable for complex sample testing, also effectively prevents ghost peak generation from high temperature sampling process. There are optional methods for achieve Grob stop flow injection: distributary/ distributary less, capillary column with wild caliber direct injection, magnet valve with time program distributary gas circuit on off. suitable for trace material testing.

Hua Guang located in the largest famous industry city of China--Shenyang. Shenyang not only has the earliest analysis instrument producing history record, it also represents the advanced technology of China in analysis technology and application science area.

In 1998, Hua Guang officially found with imported Japanese technology and production technics. With ten years research and invention, Hua Guang now becomes a professional lab instrument company who provides design, research, production, sales, service and expert laboratory solutions.

Hua Guang incorporated by HG precision instrument co., Ltd, HG analysis technology and application science academe and HG analysis testing centre. The production factory of HG located HG industry part in Shenyang development zones, the sales headquarter placed in Galaxy building in the economy centre

Excellent development capacity and production instruction technology dress the product of HG with outstanding technics and advance technology. With perfect modern quality examining system, it has been qualified by ISO9001: 2000 international quality management system.

HG major in producing large scale lab instrument which among the environment protection, health and safety, food detection, etc areas. Include atomic absorption spectrometer which enable to analysis and test trace elements and toxic metal, gas chromatography and high performance liquid chromatography which enable to test organic material in ration, character etc.

With excellent research capacity group endure HG with strong innovative ability, with years strive self improvement, our new invented LAB600 has been released which with 6 patents and numerous rewards. Its advanced technology and multiple functions impress BCEIA trade meeting and won the golden rewards which is the most effective and large professional analysis instrument trade meeting.

We freely guarantee the main board a whole-life of using which with wiring parts highly integrated in.
Our products are wildly used among metallurgy, petroleum, chemical industry, geology department, science research, university, food testing, health care and safety and environment protection etc. And honored trade our products to 20 national provinces and exported to whole Asian, Africa, and Europe countries.

We uniformly forces on building a harmonious environment between healthy life and healthy environment and donates our best technology support and services for this mission.

HG business object: providing professional integrative optimized laboratory solution.
HG organization culture: successful business is running start from trust and encourage, and faithful heart never stop.

We are holding a warmest heart and looking forward for the cooperation from the word.
