  1. hi,
    I'm really interested in what type of solvent did you use to see the asbestos better?

  2. How to identify crystanility by polarizning microscope ? need a application protocol
  3. Excellent, could you tell me I could get the compact fume hood you are using please?
  4. Thanks - are the filter compensators necessary to identify fibers in vermiculite if I'm not worried about false positives?
  5. I'd like to see demos for the other methods,this was great! Thanks
  6. What other laboratory methods are used for theidentification of asbestos ?
  7. Thank you for putting this up!
  8. It is hard to see on the video, but the microscopes are placed in a fume-hood, so there is constant air flow in direction from me toward the scope and further on HEPA filter, which captures asbestos fibres.
  9. There isn't any danger with asbestos this close to you?
  10. In Ontario, Canada, by law, you need to collect samples in triplicate, and each sample is tested in triplicate by EPA requirement, so, it is a lot of work.
  11. After use, the RIL is closed, so no contamination is possible as demonstrated via CCB analysis
  12. very nice, how many samples are taken from material lie insulation to have good reliability. how is air sample done ?? thank you
  13. Why have got RI Liquid on the extraction cupboard, you will be contaminating the liquid once open. The liquid should be outside the extractor cupboard, slides should be prepped outside, then bought inside the cupboard before placing suspect fibres in the liquid for identification.
  14. fiberglass
  15. There seems to be an increase in asbestos related deaths. Isn't there an alternative material?
  16. bloody awful music
