Methods

CHESTER LabNet has the capabilities to analyze samples using the following instrumentation: X-ray Fluorescence (XRF), Graphite Furnace Atomic Absorption (GFAA), Inductively Coupled Argon Plasma Atomic Emission (ICP or ICAP), Ion Chromatography (IC) and a wide variety of wet chemical methods. A list of methods commonly run by CLN, along with links to each, is provided.

CHESTER LabNet routinely receives requests for updated or most current copies of methods. Thanks to the wonders of the internet, most U.S. Government air quality methods are now available in an easily downladable/prinable form. CLN makes no claims about the currency of these methods; they are presented here as an aid to our clients. We have links to the following method sites:
