Analysis of Cracking Gas by Gas Chromatography and Domestic Analysis of Cracking Gas

As a preprocessing technique, thermal cracking can decompose non-volatile solids into fragments suitable for gas-phase analysis of small molecules, thereby generating reproducible characteristic spectra of non-volatile samples. This method can analyze samples of various materials such as polymer, rubber, various fibers, coatings, etc. This technology can be applied in different fields such as polymer science, microbiology, biotechnology, healthcare, forensic testing, energy, geology, and geochemistry.

Actual sample test spectrum

Advantages of use:

Sample processing: No pre-treatment required, no use of hazardous chemical reagents, no generation of exhaust gas or waste liquid. Experimental site: No need to build a professional laboratory, a 2-meter operation platform, equipped with air conditioning; Personnel configuration: One operator is sufficient, who understands basic computer operations; Short testing time: less than 20 minutes, sample preparation time * quick screening needs of enterprise users; Low usage cost: less than 2000 yuan per year; Convenient and fast: direct solid or liquid injection, four step operation to obtain results; Built in standard curve: Geng adds intuitive judgment to determine whether the material exceeds the limit of ortho benzene; No need to inject standard samples every day.
