LCS Laboratory Inc., developed and offers a number of tests for surface contamination. Thousands of chemicals and materials can be tested and quantified. If you do not see what you are looking for, please email us to discuss your project. Our most popular tests of surface contamination include:
- Abietic Acid (pine rosin) on wipes
- Asbestos fibres on wipes
- Dust for chemical identification
- Glass fibres on wipes
- Metals, including Lead, on wipes
- Mold on tape lifts
- Perchlorates on wipes
- Polynuclear Aromatic Hydrocarbons (PAH) on wipes
- Silica Crystalline, including α-Quartz and Cristobalite on wipes or by microvacuuming
- Silicone Oil on wipes
- Soot on wipes
- Tetrahydrocannabinol on wipes
The entire variety of sampling procedures can be divided into 5 groups:
- Wipe samples. These samples are collected from nonporous surface like glass, metal, ceramic, or plastic by carefully collecting a contaminant with gauze or paper wipe. Usually standardized area of 1 sq.ft. or 100 cm² are used to quantify levels of contamination. The method is commonly used for soluble or extractable chemicals like oils and metals.
- Micro vacuuming. This methods can be used to collect loose dust from both porous and non-porous surfaces. Dust samples are collected on standard cassette and can be further tested for any chemical or material.
- Tape lift. Sample is collected on clear duct tape by a single touch of the surface with a glued side of the tape. This method is commonly used for direct microscopic study of the samples.
- Staining. The surface of concern is sprayed with color developing chemicals. If a chemical of concern is present, the color stain appears. This method is rarely used because it is destructive, contaminates the surface with chemicals, and is purely qualitative.
- Nondestructive extraction from clothes and fabric
If you do not see the test that you are looking for please ask. We might have it but didn’t have chance to publish it on our website. To order your sampling equipment or to discuss your project, please email us.

Hi Joseph.
It is different from country to country. In Ontario, Canada asbestos in air is regualated as fibes at 0.01 ff/cc (Ontario Asbetos reg. 278/05)
