Firstly, we don’t do instant tests. Instant tests are for cowboys and are not recommended or compliant with the new standards.
When sampling for methamphetamine and its precursors on surfaces using methanol moistened wipes, there are a number of sampling techniques that have been developed by the National Institute for Occupational Safety and Health (NIOSH) and the industry:
  1. Individual sample technique (Discreet Sample)
  2. Multi-wipe field composite technique
  3. Laboratory composite technique
Meth Testing Hawkes Bay offer all options and use them depending on what is required and balanced with cost to the client.
For more detailed technical information on each sampling technique see here.
