6 Other Considerations Regarding Automatic Sampling Equipment 

Since automatic samplers generally include an inlet tube, the development of problematic biological films within the tube and control unit can arise. The influence of automatic sampling equipment on biological oxygen demand (BOD) test nitrification in nonnitrified final effluent has been evaluated [45]. Samples were tested for BOD, carbonaceous BOD,
