HPLC (High Performance Liquid Chromatography) field survey analysis device and analysis method thereof

The invention discloses an HPLC (High Performance Liquid Chromatography) on-site engineering investigation analysis device which comprises a main board, the three-phase power insertion terminal is connected with the main board; the single-phase power insertion terminal is connected with the main board; the network port is connected with the mainboard; the plurality of connection interfaces are connected with the mainboard; the USB interface is connected with the mainboard; and the DB9 interface is connected with the mainboard and is used for being connected with an upper computer. According to the HPLC on-site engineering investigation analysis device and the analysis method thereof, spectrum analysis can be carried out in the fault time period when communication is abnormal or even communication cannot be carried out on site, interference frequency points are found out, and therefore the interference points can be avoided on site in the mode of manually configuring the frequency points, on one hand, the comm
