Cleaning Validation Protocol for Sample Container


Learn how to validate the cleaning procedure of sample container using spectrophotometer.

1.  PURPOSE:

     This is to establish the documented evidence to verify the consistent performance of the Cleaning process of Sample Container for all Spectroscopy analysis.

2.  SCOPE: 

     This protocol is applicable to carry out the process validation of Cleaning to ensure the Sample Containers has no residues to mix up with other reagents used in QC Lab.

3.  ABBREVIATION:

        NA - Not Applicable
        NMT - Not More Than
        PPT - Parts Per Thousand
        QA - Quality Assurance
        QC - Quality Control

4.  RESPONSIBILITY:

    •  It is the responsibility of Quality personnel to prepare the protocol and execute the validation process as per this protocol.
    •  It is the responsibility of Quality Control Manager to review the protocol.
    •  It is the responsibility of QA Manager to approve the protocol.

5.  INTRODUCTION:

    Sample Containers used for Spectroscopy analysis are subjected to Cleaning to ensure that no mix-up of the reagents occurs.

6.  DOCUMENTATION:

        NA  

7.  EQUIPMENT/ MATERIALS REQUIRED:

    •  Spectrophotometer
    •  Sample Container
    •  Conductivity Meter
    •  pH Meter
    •  Washing Solution
    •  Distilled Water
    •  Reagent (Colored Reagent preferred)

8.  PROCEDURE:

NEW SAMPLE CONTAINER (20mL / 50mL):

    •  Take a fresh new Sample Container and Rinse with Distilled water twice (Holding Time 30 Seconds)
    •  Fill 20 mL of Distilled water in 50 mL Sample Container and measure the absorbance at 505 nm, Conductivity, pH, TDS and Salinity.

USED SAMPLE CONTAINER:

1.  Take a fresh new Sample Container and Rinse with Distilled water twice (Holding Time 30 Seconds).
2.  Fill 20 mL of reagent in 50 mL Sample Container and measure the absorbance at 505 nm, Conductivity, pH, TDS and Salinity.
3.  After measurement, take the same Sample Container, Rinse with Distilled water twice (Holding Time 30 Seconds).
4.  Fill 20 mL of distilled water in Sample Container and measure the absorbance at 505 nm,   Conductivity, pH, TDS and Salinity.
5.  After measurement, take the same Sample Container, Rinse with washing solution and then rinse with distilled water twice (Holding Time 30 Seconds).
6.  Fill 20 mL of distilled water in Sample Container and measure the absorbance at 505 nm, Conductivity, pH, TDS and Salinity.
