This standard specifies the gas chromatography and film-covered cell electrochemical method for the determination of the oxygen content in the gas phase above the industrial butadiene liquid. The gas chromatography measurement range is 100mL/m3-5000mL/m3 , the measurement range of thin film covered battery electrochemical method is 1mL/m3-5000mL/m3. This standard does not address all safety issues associated with use. Therefore, it is the user's responsibility to take appropriate safety and health measures to ensure compliance with the relevant national laws and regulations.
