Volume Accuracy Failure - 850-DS Dissolution Sampling

During volume accuracy test of our 850-DS Dissolution Sampling, the difference of the sample volume for position #2 for 10mL was higher than 0.5mL, being that specification is lower than 0.25mL.

How can we calibrate the equipment to sample the right volume?

We performed the full range volume dispense (in the calibration screen), but we are not sure how to use the data to do the equipment calibration.

Could you help us, please?

  • Hello Suzany-
    Before do volume accuracy, one should perform volume calibration and it can be done using the calibration Tab key. 
    Full Procedure can be found on your initial OQ or Lycrecia provided manual. 
    Position 2 seems way off; you might need to contact Agilent service. 

    Thanks
    Kind Regards

  • Thank you Khurrum! I will take the initial documentation to check. Good idea! Thank you!
