Particle Counter in Pharmaceuticals: Complete SOP Guide

Maintaining air quality in cleanroom environments is critical in the pharmaceutical industry. A Particle Counter in pharmaceuticals plays a key role in monitoring airborne particles to ensure compliance with regulatory standards and product safety.

This guide explains the standard operating procedure (SOP) for using a particle counter, specifically the Met One 3400 model, in a clean area.

Objective

The objective of this SOP is to establish a clear and standardized method for operating a Particle Counter in pharmaceuticals to accurately measure airborne particles in controlled environments.

Scope

This procedure applies to the operation of the Met One 3400 particle counter used in pharmaceutical cleanrooms for environmental monitoring.

Responsibility

• Quality Control Officer/Executive
  Responsible for operating the particle counter and ensuring accurate data collection.

Accountability

• Quality Control Manager
  Oversees compliance, verifies results, and ensures proper implementation of the SOP.

Procedure for Operating Particle Counter

1. Logging In

To begin using the Particle Counter in pharmaceuticals, follow these steps:

• Switch ON the main power.
• Navigate to Counter Navigation → Select Factory.

Login Methods

Depending on the system status, use one of the following:

• After startup:
  Tap the screen. If password protection is enabled, login is required.
• Switching users:
  Tap the Lock icon to log out the current user, then tap again to log in.

Login Steps

1. Tap the Name field and enter your username using the touchscreen keyboard.
2. Press Enter.
3. Tap the Password field and input your password.
4. Press Enter again.
5. If successful, the main screen appears. Otherwise, retry login after a failure message.

2. Taking Particle Counts

Before starting, always ensure the equipment is properly prepared.

⚠️ Important: Remove the protective cap from the inlet tube to avoid equipment damage.

Counting Procedure

1. Remove the protective cap from the inlet (top of the device).
2. Confirm the display shows Counter Navigation.
3. Tap Sample on the screen.
4. Press the Run icon to start particle counting.

During Operation

• The Run icon changes to a Stop icon during measurement.
• The screen displays:
  • Particle counts
  • Environmental parameters (temperature, humidity, air velocity)

Alarms

• Alarms appear as flashing red text with optional audible alerts.
• These indicate environmental or count deviations.

Stopping the Count

• Counting stops automatically after completion.
• To stop manually, press the Stop icon.

Final Display

Once complete, the system shows:

• Total particle count
• Recorded environmental parameters

Additional Settings

Operators can adjust:

• Alarm limits
• Measurement units
• Date and time settings

These configurations ensure accurate and compliant monitoring in pharmaceutical environments.

Why Particle Counter is Important in Pharmaceuticals

A Particle Counter in pharmaceuticals is essential for:

• Maintaining cleanroom classification (ISO standards)
• Preventing contamination in drug manufacturing
• Ensuring regulatory compliance (FDA, GMP)
• Protecting product quality and patient safety

Frequently Asked Questions (FAQs)
