The First Gas Chromatograph Training Course in 2019 Was Successfully Held

In order to enable distributors to better understand and promote the technical knowledge and development of domestic gas chromatography and supporting headspace sampler, thermal desorption instrument, purge and trap, and cracker, and to expand the business scope, Kejie Company launched a company in June 2019. On March 29th, we cooperated with domestic well-known gas chromatograph supporting product manufacturers to hold professional knowledge training on gas chromatograph and supporting products in Nanjing.

This meeting is mainly aimed at instrument dealers. The content of the meeting is as follows:

In the morning, Mr. Zhao gave a speech on the basic principle and structure of gas chromatograph, the basic principle and application fields of supporting products, and exchanged difficult points with the students.

The main contents are:

1. An introduction to gas chromatograph

Gas chromatograph refers to a chromatographic analysis instrument that uses gas as the mobile phase. The principle is to use the difference in boiling point, polarity and adsorption properties of substances to realize the separation of mixtures. After the sample to be analyzed is vaporized in the vaporization chamber, it is brought into the chromatographic column by an inert gas (ie, carrier gas, also known as mobile phase), and the column contains a liquid or solid stationary phase. A partition or adsorption equilibrium is formed between the stationary phases. With the flow of the carrier gas, the sample components are repeatedly distributed or adsorbed/desorbed during the movement. The components with high concentration in the carrier gas flow out of the chromatographic column first, while the components with high concentration in the stationary phase are distributed in the stationary phase. flow out later. The components flow out of the chromatographic column and then enter the detector to be measured. Commonly used detectors include electron capture detector (ECD), hydrogen flame detector (FID), flame photometric detector (FPD) and thermal conductivity detector (TCD).

2. The types of gas chromatographs

a. GC6891N laboratory high-end gas chromatograph

b.GC 5890P (EPC) Gas Chromatograph

c.GC5890N high performance gas chromatograph

d.GC5890C practical gas chromatograph

3. Application fields and technical parameters of various gas chromatographs

a. Main application fields of GC6891

Petroleum exploitation and refining, petrochemical, fine chemical, food safety, environmental protection,

Electronic high-purity gas industry, scientific research institutes, quality inspection, safety supervision,

Analysis and testing in the fields of public security forensics and national security.

b.GC 5890P (EPC) gas chromatograph (high end)

Petroleum exploitation and refining, petrochemical, fine chemical, food safety, environmental protection,

Electronic high-purity gas industry, scientific research institutes, quality inspection, safety supervision,

Analysis and testing in the fields of public security forensics and national security.

c.GC5890N high performance gas chromatograph (conventional)

Petroleum, chemical, food, pharmaceutical, environmental disease control, safety supervision, water affairs, electric power, metallurgy, scientific research institutes, quality inspection departments.

In the afternoon, on-site teaching was carried out on the actual instrument.

After the training, the trainees expressed that they have benefited a lot.

It is hoped that through this study and communication, dealer friends can have a deeper understanding and understanding of Kejie and domestic gas chromatographs, jointly establish a national brand, and work together to create great achievements!

Kejie Launched A Special Gas Chromatography Instrument For The Analysis Of Automotive Interior Materials

changior — Thu, 20 Dec 2018 00:46:57 +0000

Kejie Launched A Special Gas Chromatography Instrument For The Analysis Of Automotive Interior Materials

Air pollution in cars has been identified as one of the top ten threats to human health by the World Health Organization. The composition of volatile organic compounds in the air in the car is relatively complex, including hydrocarbons, aldehydes, ketones and other chemical substances. These harmful substances, such as formaldehyde, benzene, toluene, xylene, TVOC, etc., will cause health problems for drivers and passengers unconsciously, especially in closed cars, through breathing and contact channels.

These hazards are generated from various accessories and materials of the new car itself, such as plastics in the car, leather covers, etc. The interior structure of the car is mainly composed of leather, fiber and various engineering plastics, and these materials need to use harmful substances such as formaldehyde and benzene during production. Companies with a sound quality management system will conduct a round of “disinfection” before interior components leave the factory, but due to cost, not all parts supporting companies will do enough “disinfection”. Some interior decorations and devices such as floor coverings, seat cover cushions, and adhesives containing harmful substances are also likely to cause pollution in the car and produce toxic gases.

Nanjing Kejie Analytical Instruments provides TVOC testing instruments and analysis solutions for automotive interior manufacturers to ensure the safety of automotive interior products.

Kejie TVOC detection gas chromatograph has the following characteristics:

* High precision, multifunctional.

* New integrated digital electronic circuit, high control precision, stable and reliable performance, up to 0.01 ℃ temperature control accuracy.

* With power-on self-diagnosis function, stopwatch function (convenient for flow measurement), running timer function, power failure storage protection function, keyboard lock function, anti-power mutation interference function, networked data communication and remote control functions.

* The unique design of the sampling system allows for lower detection limits.

* The unique inlet design solves injection discrimination; the dual-column compensation function not only solves the program drift caused by temperature rise, but also subtracts the influence of background noise, which can obtain a low detection limit.

* With packed column, capillary split/splitless injection system (with diaphragm cleaning function)

* Optional automatic/manual gas six-port injection valve injector, headspace injector, thermal desorption injector, pyrolysis furnace injector, methane reformer, and automatic injector.

* Program heating, precise control of furnace temperature, stable balance is faster.

* The volume of the column box is large, and the intelligent rear door system has stepless variable air flow in and out, which shortens the stable equilibrium time of each detector system after the programmed heating/cooling; Heating furnace system: ambient temperature +5 °C ~ 420 °C; 7-step temperature programming, The heating rate is 0.1～120℃/min; the furnace temperature can be re-calibrated by the user, the upper limit temperature can be arbitrarily set within 420℃, and the user decides the temperature balance time of the heating furnace.

* High sensitivity and high stability detector to meet the needs of different solutions

* Can be installed with flame ionization detector (FID), thermal conductivity cell detector (TCD), electron capture detector (ECD), flame photometric detector (FPD), nitrogen phosphorus detector (NPD), photoionization detection Detector (PDHID) six detectors.

Various detectors can be independently temperature-controlled, and the hydrogen flame detector is easy to disassemble and install for cleaning or nozzle replacement.

* Thermal conductivity cell detector (TCD) stabilization time: ≦10min

It can accurately detect the toxic gas content in the car interior to ensure the air in the car for the riders.
