The invention relates to a tail gas analysis device and method. Comprising the steps that a sampling pump collects ship tail gas in real time, the ship tail gas enters a pretreatment unit to be pretreated, particulate matter and organic matter in the ship tail gas are removed, and water treatment is conducted on the ship tail gas; the temperature and humidity sensor detects the temperature and humidity of the pretreated ship tail gas in real time, whether the temperature and humidity detected by the temperature and humidity sensor in real time reach the pretreatment standard or not is observed, and if yes, the ship tail gas enters the gas analysis unit; if the temperature and the humidity do not reach the treatment standard, the ship tail gas is pretreated again through the PID control unit until the temperature and the humidity of the ship tail gas reach the standard, the ship tail gas enters the gas analysis unit for gas analysis, and finally the sulfur content of the fuel oil is calculated. 本申请是关于一种尾气分析装置及
