Wet Chemistry

There are a number of test procedures for which advanced instrumentation is simply impractical and unnecessary.  These traditional wet chemistry methods are still utilized for air testing.  Our traditional wet chemistry services include spectrophotometric, titrimetric, and a variety of extraction procedures.

These analyses fulfill requirements for several specific EPA, NIOSH and NCASI air test methods, including EPA 6/8 for sulfates and EPA 323 for formaldehyde.  Analytes including ammonia, sulfates, formaldehyde, and phenol can be determined using these fast yet reliable procedures.

SO2/ SO3 (EPA Method 6/8)

EPA Method 8  (determination of sulfuric acid mist and sulfur dioxide from stationary sources) is being utilized for a broad variety of stationary sources- sometimes even beyond the scope of its original intent.  As a result, an increasing number of sources are tested which can impart significant levels of matrix effects to these field samples, particularly ammonia from power generation facilities utilizing ammonia injection technology.

To deal with matrix interferences, we have developed a number of interference reduction procedures in the analytical preparation of these samples.  As further confirmation (or as a primary test method in many cases), we will typically run two or more samples by ion chromatography, particularly if a high level of interference is suspected.
