Method 21 Calibration Services

EPA Method 21 is a procedure used for detecting volatile organic compound (VOC) leaks in industrial equipment such as valves, pumps, compressors, and flanges. Method 21 uses a portable VOC analyzer to measure leak rates based on a known reference compound, usually methane. However, these analyzers are only as accurate as their last calibration. That’s where EPA Method 21 calibration services come into play.

Proper calibration involves exposing the analyzer to certified calibration gas and zero air to test and adjust its performance. When our technicians come to your facility, they will confirm the response time and verify that the instrument operates within the EPA’s required accuracy range.

Why is Method 21 Required by the EPA?

The Environmental Protection Agency (EPA) requires Method 21 under the Clean Air Act as part of the Leak Detection and Repair (LDAR) program. To mitigate emission risks and reduce the impact of VOCs from industrial equipment, the Clean Air Act mandates regular inspections using EPA Method 21. Facilities are required to track inspection intervals and actively monitor for leaks using a properly calibrated analyzer. This helps facilities:

  • Avoid unnecessary product loss due to undetected leaks
  • Reduce exposure risks for employees working in hazardous environments
  • Maintain compliance with both federal and state environmental regulations
  • Demonstrate due diligence during EPA or third-party audits

How Our Calibration Services Work

Jorgensen’s Method 21 calibration services are designed to keep your monitoring equipment fully compliant with EPA regulations. Our trained technicians start the calibration process by applying certified calibration gas to verify the analyzer’s linearity and precision. If your operation requires a specific leak definition, we adjust accordingly with the appropriate calibration gas mixture.

The calibration process at Jorgensen includes:

  • Establishing a clean baseline using zero air for accurate VOC detection
  • Measuring response time to confirm the analyzer reacts quickly enough to detect leaks
  • Checking span drift to ensure measurement stability over time

We also follow Section 8 of Method 21, which requires calibration before each use or on a quarterly basis. All results are recorded in EPA-compliant logs to ensure traceability and streamline audits.

Ensuring Compliance with EPA Standards

Staying compliant with EPA Method 21 involves more than checking for leaks. The EPA also mandates precise calibration, comprehensive documentation, and a thorough understanding of inspection protocols. With our help, you can reduce the risk of enforcement actions and maintain safe, compliant operations that stand up to scrutiny.

Here are a few ways Jorgensen supports your compliance efforts:

  • Detailed calibration logs that meet EPA documentation standards
  • Instrument certifications verifying that analyzers meet performance criteria
  • Scheduled service plans that align with regulatory inspection timelines
