UV Meter Usage Procedure

Purpose

The purpose of this Standard Operating Procedure (SOP) is to establish the procedures for the proper operation of a UV meter. This ensures accurate measurement of ultraviolet light intensity in photostability studies and other laboratory environments.

Scope

This SOP applies to all personnel using UV meters for measuring ultraviolet light intensity within the facility.

Responsibilities

• Stability Manager: Ensure compliance with this SOP and oversee the proper use of UV meters.
• Laboratory Technicians: Operate the UV meter, document measurements, and report any deviations or malfunctions.
• Quality Assurance (QA) Team: Review and approve UV intensity measurement records and reports.

Procedure

1. Preparation:
   • Ensure that the UV meter is clean and in good working condition.
   • Verify that the UV meter is within its calibration due date and properly certified.
   • Familiarize yourself with the UV meter’s user manual and operational procedures.
2. Measurement Setup:
   • Turn on the UV meter by pressing the power button.
   • Select the appropriate measurement mode (e.g., UVA, UVB, or UVC) as per the
     

     “Unveiling the Secret of Drug Stability: Exploring Chemical Kinetics to Ensure Long-lasting Effectiveness and Safety”

     study protocol.
   • Ensure that the sensor is clean and free from any obstructions.
3. Taking Measurements:
   • Position the UV meter’s sensor at the location where the UV light intensity needs to be measured.
   • Hold the sensor steady and ensure it is facing the UV light source directly.
   • Allow the UV meter to stabilize and display a consistent reading.
   • Record the UV light intensity reading in the measurement log.
   • Repeat the measurement at multiple points within the photostability chamber to ensure uniform UV exposure.
4. Data Recording:
   • Document all UV light intensity readings in a measurement log, including the date, time, and location of each measurement.
   • Record any observations or anomalies noted during the measurements.
   • Ensure the measurement log is complete, accurate, and signed by the personnel performing the measurements.
5. Post-Measurement:
   • Turn off the UV meter and store it in a clean, dry place.
   • Ensure that the UV meter is stored in a protective case to avoid damage.
   • Report any deviations or malfunctions to the Stability Manager and QA Team.
6. Maintenance:
   • Perform regular maintenance of the UV meter according to the manufacturer’s recommendations.
   • Calibrate the UV meter periodically to ensure accuracy.
   • Keep maintenance and calibration records up-to-date and accessible for review.
7. Record Keeping:
   • Maintain all measurement logs and calibration records in a centralized location for easy access and review.
   • Ensure electronic data is backed up regularly and securely stored.
   • Archive records according to the facility’s document retention policy and regulatory requirements.
