The methods are arranged alphabetically by method name, and some method names may refer to a group of related substances. It is possible for you to rearrange the methods in order of method number if you find this arrangement more convenient.

1. METHOD FINDER

The easiest and fastest way to locate a method is to refer to the Method Finder inside the front cover of the Manual. The Method Finder is an alphabetical listing of common chemical names and their associated methods with information on Compound, Method Number, Method Name, Sampling Rate, Minimum Volume, Maximum Volume, Extraction Solvent, Analytical Technique, and Sampler for quick reference.

2. METHOD NUMBERING SYSTEM

Substances having the same sampler, sample preparation and measurement technique may be grouped together in one method (note that this numbering system is unchanged from the Third Edition):

Method # Substances
0001–0799 General air samples
0800—0999 Bioaerosols
1000–1999 Organic vapors on charcoal
2000–3499 Organic vapors on other solid sorbents
3500–3999 Organic vapors on other samplers (e.g., liquids, direct-reading)
4000–4999 Organic vapors on diffusive samplers
5000–5999 Organic aerosols
6000–6999 Inorganic gases
7000–7999 Inorganic aerosols
8000–8999 Biological samples
9000–9999 Bulk samples
