Product Introduction

蓝色线条.jpg

The main component of natural gas is CH4 (methane), which is colorless, odorless, non-toxic, and non corrosive. It also includes a certain amount of ethane, propane, and heavy hydrocarbons, as well as small amounts of nitrogen, oxygen, carbon dioxide, and sulfides. Natural gas is not only a high-quality fuel, but also a raw material for the production of chemicals such as acetaldehyde, acetylene, ammonia, carbon black, ethanol, formaldehyde, hydrocarbon fuels, hydrogenated oil, methanol, nitric acid, synthesis gas, and vinyl chloride.

The natural gas specific gas chromatograph launched by Tate Instruments can quickly detect the composition and content of natural gas, and calculate the calorific value of the sample through dedicated software. It is a commonly used analytical equipment for natural gas companies, gas appliance manufacturers, gas appliance measurement departments, scientific research, environmental protection, and gas distribution units.
