FAQ

How do I send samples to you?

Most filter samples can be shipped in boxes with no special packaging other than making sure the filters are well enough protected to not be damaged during shipment. Liquid samples (impinger solutions etc) should be packaged based on DoT HazMat shipping standards. Both FedEx and UPS have HazMat specialists who can help you to ensure your shipping methods are safe and legal.

Samples can be shipped to us at our mailing address (see contact us for details). Note that a completed Chain of Custody (CoC) is required to meet legal documentation requirements for nearly all samples. A downloadable version of CLN's CoC is available by clicking link below.

I've never done air quality sampling before, where do I start?

We recommend contacting an air quality engineering firm if you have never done air sampling before. Unlike soil and water sampling, air sampling requires a great deal of both specialized equipment and skill (and a whole lot of luck!). Feel free to contact us for information on various air quality engineering firms, or refer to the EPA methods.


Does CHESTER LabNet perform analysis for ORGANIC constituents of air?

Although CHESTER LabNet does not perform organic air analyses we work with several other laboratories that do. If you would like a referral to one of these please contact us.

I am trying to sample an (obscure, delicate) source for (engineering, compliance, litigation) purposes and was wondering what method I should use?

We are more than happy to help you with comparing methodologies if you contact us, however we strongly recommend that you first contact the governing agency ultimately responsible for the site. If there is no agency, the most legally defensible data will use 40 CFR 60 or other US EPA sanctioned methods. The more you deviate from the method, the less legally defensible it becomes.
