Volatile phenol analyzerIt is a specialized analytical instrument used to detect the content of volatile phenols in samples such as water, soil, and industrial wastewater.

Volatile phenol analyzerOperation process:

Sample pretreatment: Take an appropriate amount of water sample and place it in a distillation flask. Add phosphoric acid until acidifiedpH≤4Add copper sulfate solution to remove sulfide interference, connect the distillation device, and collect the distillate250mLFill the volumetric flask to the desired volume.

Instrument calibration: Prepare a series of phenol standard solutions with different concentrations, process them according to the color development steps, place them in the instrument for calibration, draw the standard curve, and save it.

Sample testing: take10mLPlace the distilled liquid in a colorimetric tube and add buffer solution in sequence4 -Aminoantipyrine solution and potassium ferrocyanide solution, shake well and let stand 10 Complete color development in minutes; Place the colorimetric tube into the instrument colorimetric cell, click "Detect", and the instrument will automatically read the absorbance and calculate the concentration value.

Result recording: After the instrument displays the detection results, the data can be directly printed or exported, recording information such as sample number, detection time, concentration value, etc.

Application field

Water quality monitoring:

The volatile phenol analyzer is an important tool for water quality monitoring, which can accurately measure the volatile phenol content in industrial wastewater, wastewater treatment plant effluent, surface water, groundwater, drinking water, etc.

Ensure that water quality meets relevant standards and protect water resource safety.

Environmental monitoring:

Used to monitor volatile organic compounds in the atmosphere, such as benzene, toluene, xylene, etc., and evaluate air quality.

Detect the content of volatile phenols in soil and evaluate the degree and scope of soil pollution.

Industrial hygiene:

Detect chemical residues and harmful gas emissions during the production process to ensure the safety of the production environment.

Protect the health of workers and prevent the occurrence of occupational diseases.

Indoor air quality assessment:

Detect volatile organic compounds such as formaldehyde and benzene in indoor environments to assess the health risks of indoor air.
