    Abstract: Based on gas chromatography-mass spectrometry (GC-MS) and a custom-made sample prepartion unit, an in-situ system was developed for atmospheric nitrogen trifluoride (NF3) measurement. Precision, accuracy and detection limit were 3.9% (1σ), 1.2% and 0.23×10-12, respectively, which indicate the system could be used for in-situ measurement of atmospheric NF3. Field in-situ measurement was conducted during September 2016 to May 2017 at the Shangdianzi Background Station with a time resolution of 130 minutes for air samples. Both background and pollution samples were captured. Using the pollution filter, 53.1% samples were selected as background data with an average mixing ratio of the 1.72×10-12, consistent with the background level observed at Mace Head, Ireland and Trinidad Head, USA located at the similar latitude, while the median mixing ratio of polluted samples was 2.41×10-12, which was 40.1% higher compared to the average background mixing ratio.
