Other Types of PMI Equipment

PMI guns, which use X-ray Fluorescence (XRF) technology, are among the most common and portable types of PMI equipment.

But they are not the only type of PMI equipment that inspectors use.

Here are three other common types of PMI equipment:

1. Optical Emission Spectrometry (OES)

OES involves sparking the material’s surface and analyzing the emitted light’s spectrum. OES equipment is highly accurate and can detect a wider range of elements, including light elements like carbon, which are difficult for XRF to detect.

2. Laser-Induced Breakdown Spectroscopy (LIBS)

LIBS is a newer technology, in which a high-intensity laser pulse is focused on the material surface, creating a plasma. The light emitted from this plasma is then analyzed to determine the material’s composition. Like PMI guns, LIBS equipment is portable and offers rapid analysis to support work in the field.
