IANZ Accrediation Number 636.

SAMPLE ANALYSIS

Bulk Analysis

CES is IANZ accredited for identification of asbestos in bulk samples. We use a combination of gravimetric reduction (refer Australian Standard AS4946 Method for the Qualitative Identification of Asbestos in Bulk samples) and polarised light microscopy (PLM) on the majority of samples. 

Dust Analysis

We have tried several methods for collecting samples including surface dust and in our experience the ghost wipes are the most effective method of collecting settled dust from a surface to determine the presence of asbestos. Ghost wipes are manufactured in the United States and provided in individually sealed packages reducing contamination issues.

Once the sample has been collected, being wiped over the entire surface or a large representative area, the wipe with the collected dust is ashed at 440 degrees C. This ashing process removes other fibre types that may be present and any organic material, and the ghost wipe fabric reduces to a trace amount. The remaining ashed sample is then prepared for analysis by polarised light microscopy.
