Calibration and Operation of a High Volume Mass Flow Controlled Ambient Particulate Sampler

Introduction

This tutorial provides a step-by-step guide on how to calibrate and operate a Tisch Environmental Mass Flow Controlled High Volume Ambient Particulate Sampler. Proper calibration and operation are essential for accurate measurement of particulate matter in the environment, making this guide relevant for environmental scientists, technicians, and researchers.

Step 1: Gather Necessary Equipment

Before beginning the calibration and operation process, ensure you have the following items:

• High Volume Mass Flow Controlled Ambient Particulate Sampler
• Calibration worksheets (available at https://tisch-env.com/calibration-worksheets/)
• Precision scale
• Standard or reference particulate filters
• Calibration gas (if applicable)
• Personal protective equipment (PPE), such as gloves and safety goggles

Step 2: Prepare for Calibration

Follow these preparations to ensure accurate calibration:

1. Check the sampler's condition:

   • Inspect the sampler for any visible damage or wear.
   • Make sure all components are clean and functioning properly.

2. Set up the calibration environment:

   • Conduct calibration in a controlled environment to minimize external factors.
   • Ensure stable temperature and humidity conditions.

3. Follow the calibration worksheet:

   • Download and print the calibration worksheet for your sampler model.
   • Familiarize yourself with the worksheet layout and required data points.

Step 3: Calibrate the Sampler

To calibrate the sampler, perform the following steps:

1. Connect the sampler to the power source:

   • Ensure the sampler is properly powered and operational.

2. Set the flow rate:

   • Adjust the flow rate to the desired setting as specified in the calibration worksheet.

3. Use a precision scale:

   • Weigh the filters before and after sampling to determine the mass of particulate matter collected.
   • Record the data on the calibration worksheet.

4. Perform zero and span checks:

   • Conduct a zero check by running the sampler without any particulate matter.
   • For span checks, introduce known amounts of particulate matter and record the responses.

5. Adjust settings as needed:

   • If discrepancies occur, adjust the flow rate or other settings according to the calibration worksheet instructions.

Step 4: Operate the Sampler

Once calibrated, you can begin operating the sampler:

1. Select sampling location:

   • Choose a location that represents the ambient air quality you wish to measure. Avoid areas with obstructions that could affect airflow.

2. Install the filter:

   • Place the appropriate filter in the sampler and secure it according to the manufacturer’s instructions.

3. Start sampling:

   • Activate the sampler and monitor the flow rate and operation status.
   • Document the sampling time and environmental conditions.

4. End sampling and document results:

   • After the desired sample duration, turn off the sampler.
   • Weigh the filter again and record the results in your calibration worksheet.

Step 5: Analyze Data

After completing the sampling process:

1. Calculate particulate concentration:

   • Use the weight differences of the filter before and after sampling to calculate the concentration of particulate matter.

2. Review calibration data:

   • Ensure that the calibration results are consistent and validate the accuracy of your measurements.

3. Store data securely:

   • Keep your calibration worksheets and sampling data organized for future reference.

Conclusion

Calibrating and operating a High Volume Mass Flow Controlled Ambient Particulate Sampler is essential for accurate air quality monitoring. By following these steps, you can ensure your sampler is functioning correctly and yielding reliable data.
