Surface contamination testing is a crucial process that helps identify the presence of contaminants on surfaces where they are unwanted and undesired.

There are several methods for sampling surface contamination for laboratory testing, including:

• Wipe samples: These samples are collected from nonporous surfaces like glass, metal, ceramic, or plastic by carefully collecting a contaminant with gauze or paper wipe.
• Micro vacuuming: This method can be used to collect loose dust from both porous and non-porous surfaces.
• Tape lift
• Staining
• Nondestructive extraction from clothes and fabric
• Total Organic Carbon (TOC) Analysis: A rapid examination of extracts for residual organic materials such as oils, cleaning agents, lubricants, etc.
