Analysing for various chemicals and elements in the air using Drager

Q.  What would be the recommendation for doing the following:  (Conduct once off sampling of CO, Lead, Manganese, Mercury, Arsenic, Chromium, Nickel, Benzene, Formaldehyde, Styrene, Toluene and Tetrachloride).

 

A.  That is quite a list. As it is from an air quality report, I assume that they want it measured in the air at one or more locations. Units of measurement mg/m3 or parts per million in the air (ppm)

None of these can be determined from the fallout dust samples. It is possible to do elemental analysis on the dust to determine the Lead, Manganese, Mercury, Arsenic, Chromium, and Nickel concentrations but this will not meet the requirements or recommendations of the report as the results are given in parts per million or ppm or mass concentration, mg/kg.

My recommendation would be to research how to measure the airborne quantity of each of those chemicals and elements and then do the tests internally following the procedures.

Drager would be my starting point – http://www.draeger.com

Some of the test could be done using tubes from Drager. The tests that cannot be done in this way would then be done in other ways.

From my experience Drager have a list of chemicals that can be tested for using their pump, and the results are very useful to provide an indication of elevated levels if there are any.

By searching google for drager detection selection you will be able to download the pdf that contains the detection selection that Drager offers and if you Google Drager tube handbook then you will be able to download the handbook if required.
