SOP Title-Operation of Total Organic Carbon Analyzer (TOC)

SOP Title-Operation of Total Organic Carbon Analyzer (TOC)

 

• OBJECTIVE

To lay down a procedure  for  operation of  Total Organic Carbon Analyzer.

• SCOPE

This SOP is applicable for operation of Total Organic Carbon Analyzer located at Quality Control Laboratory.

 

• RESPONSIBILITY
• QC personal shall be responsible for implementation of procedure.
• QC Head – shall be responsible for compliance of this procedure.

 

• PROCEDURE :
  • Operation Procedure :
    • Ensure pre start up checks before operating the equipment.
    • Instrument is connected to Main power supply
    • Switch on the main power switch located on the rear panel of the instrument
    • Ensure the software version no. shall be U – 1.00
    • Ensure the sample flow rate value is  20 ± 0.5 ml/min is indicated by the four LED’s  lights on the front of the sensor.
    • If the flow rate is high , only the top LED ‘s will be ON
    • If the flow rate is low , only the bottom LED ‘s will be ON

 

• If the flow rate is not in the limit adjust the flow rate.
• Press the Menu
• Scroll the configure  Menu and press Enter
• Select Yes by pressing ▲ or ▼ to active set flow rate option. This will initiates the set      flow rate mode at the sensor. it will stay in this mode until the user changes ‘ Se Flow  Rate: Yes’ back ‘ Se Flow Rate: No’
• Select TOC general parameters and press Enter
• Turn ON the pump module and allow water to flow through the module and TOC sensor in to the cylinder  and begin the time measurement using a calibrated stop watch. It is    important that the water collection and  time start should be match.
• Collect a known volume of water with the volumetric container for a specific time, at least 3 minutes
• Record the TOC results of  water analysis report .
• Adjustment of flow rate :
• Turn off power to the pump module and TOC sensor.
• Using the pump module cover tool, carefully open the pump module to expose the driver board on the inside of module.
• Turn the potentiometer either clock wise or anti clock wise, depending on the desired
• Rotating the potentiometer either clockwise by  ¹/₄  turn will increase the flow rate by 2ml/min and anticlockwise by  ¹/₄  turn will reduces the flow rate by 2 ml/min.
• Close the cover of  the pump module and check the flow rate after each adjustment until the desired the flow rate is 20 ±0.5 ml/min is achieved.

• Cleaning:
  • Daily clean the instrument with dry and lint free cloth.
