LCS Laboratory Inc., offers air sampling kit for collection of isocyanate vapour.

220px-Isocyanate_group.svgIsocyanate is a generic term, commonly used for a group of  oil-like chemicals that are employed in production of polyurethane resins. Once the polyurethane resin is fully cured, it is generally safe and widely used in medical devices, car parts, for home insulation and other applications. The problem starts when unreacted isocyanate is accidentally trapped in resin and slowly evaporates in residential air.  Isocyanate is one of the most toxic chemical compound responsible for development of asthma, allergies, and skin reaction.

All industrial isocyanates can be roughly classified as volatile diisocyanates and non-volatile poly-isocyanates. Poly-Isocyanates, due to their low volatility, do not migrate into air and usually is of no concern to public. Meantime volatile diisocyanate can easily evaporate if not properly cured.

HDI paintThe most commonly used diisocyanates include methylenebis(phenyl isocyanate) (MDI), toluene diisocyanate (TDI), and hexamethylene diisocyanate (HDI). MDI is a frequent component of solid foams like foam mattresses, memory foam,  and house foam insulation. HDI is a major constituent of polyurethane paints and coatings.

Industrial exposure limit for volatile isocyanates in Ontario Canada (2016) is set at 0.005 ppm (5 ppb) (see ONTARIO REGULATION 490/09) . While exposure limit for general public is not established, EPA US offers the Reference Concentration (RfC) for MDI at 0.0006 milligrams per cubic meter (mg/m³) based on irritation of the nasal membranes in rats.

foam applicationLCS Laboratory Inc, offers analytical method of National Institute of Occupational Safety and Health (NIOSH, USA)  #5525 for detection of extra low level of isocyanates. The procedure can detect as little as 0.0004 (mg/m³) of isocyanate (0.04 ppb) in air and is suitable for both Industrial and Residential applications.

Your sampling kit includes one or few air sampling pumps, several cassettes specifically designed for isocyanate sampling, and sampling instruction. The instruments comes fully calibrated. You will need to connect the cassette to the pump and turn the pump on. Once you are done, please return ALL equipment to our lab for analysis. Typical cost of the project starts from $300 and depends on number of samples (rooms) you want to test. You will be also asked for a refundable security deposit for rental equipment.

To order your kit, please email us with the following information:

  • Your First and Last Name,
  • Shipping Address, Contact Phone,
  • Number of samples you want to collect. The number of samples is typically equal to number of rooms you want to test, or number of people you want to check for exposure. You use a cassette only once, so if you want to test both basement and kitchen, you need to order 2 separate samples.
  • What is the date of the sampling? We will deliver equipment by that day,
  • The standard turnaround time is 7 business days. If you want results faster, we can accommodate your request but you should expect rush service surcharge.
  • We will reply back to you with an electronic invoice which you need to pay online with a credit card to initiate your order.

Thank you for your interest and stay safe. Please email us if you have any questions
