The impurity carbon dioxide in the national standard ethylene oxide is one of the mandatory inspection items. The standard uses a thermal conductivity detector, which has low sensitivity and is difficult to measure 10ppm of carbon dioxide. High sensitivity TCD is required, which is expensive and not easy to popularize.
Haohan Chromatography developed a hydrogen flame gas chromatography method for the determination of carbon dioxide content in ethylene oxide using a methane conversion furnace. Using a gas path system with backflow, carbon dioxide can be measured below 0.5ppm with high sensitivity and accurate results. Installed on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE, and received user recognition.
Name: Portable methane conversion furnace
Model: HH-790CH4-GC
Suitable for: Agilent 4890, 5890, 6890, 7890, 7820, 8860, 8890 gas chromatographs
Haohan Chromatography Development and Production: External methane converter, small and exquisite, easy to carry, easy to install (user can complete installation), highly integrated (including gas path system, injection system, temperature control system, separation system), expandable two-dimensional/multi-dimensional system, backflow, cutting system. One machine is versatile and has high practical value.
