Comprehensive two-dimensional gas chromatography rapid time mass spectrometer
- Four-nozzle modulator:
+ Alternating cold focus and thermal desorption, variable modulation period,
+ The design has received the national utility model patent certificate
+ Optional non-consumption modulator or high-performance liquid nitrogen modulator
- Independent temperature control column furnace:
+ The gas chromatograph employs a dual thermal column design and the temperatures of the two chromatographic columns are independently controlled to eliminate temperature interference during two dimensional chromatographic column analysis.
+ The modulator is housed in a second column oven, eliminating interference from the modulation temperature conversion on peak retention time, and the chromatographic column is easy to install.
