Solvent Scan Analyses:

One of WOHL's most versatile analyses is our solvent scan which quantifies a wide variety of organic solvents off a single charcoal tube. The procedure is based on an in-house modification of the OSHA 7 method, with the main modification being the number of substances analyzed. The analysis screens all the peaks on a chromatogram and attempts to identify and then quantify those solvents which generally have established TLV's or PEL's. WOHL also identifies and quantifies non-regulated analytes. The method groups together and quantifies miscellaneous straight chained aliphatic hydrocarbons as Petroleum Distillates. Miscellaneous aromatic hydrocarbons are reported as Coal Tar Naphtha.

Our "B" compatible solvent scan emphasizes glycol ether compounds. This method also quantifies compounds utilizing a single charcoal tube. The procedure is based on the NIOSH 1403 method. The difference between our "A" and "B" solvent scans is the desorbtion solvent used. However, some of the glycol ethers in this list can be quantified using the "A" compatible solvent scan. Below is the list of our "B" compatible solvent scan analytes.

"B" compatible analytes:

Propylene Glycol Methyl Ether
Propylene Glycol Methyl Ether Acetate
Propoxy Propanol (n-)
Ethyl Lactate
Butoxethanol (2-)
Butyl Cellosolve Acetate
Methyl Carbitol
Diethylene Glycol Monoethyl Ether
Carbitol Acetate
Methyl-2-Pyrrolidione,1-
Butyl Carbitol
Butyl Carbitol Acetate
Methyl Cellosolve Acetate
Ethoxyethyl Acetate (2-)
Propylene Glycol Butyl Ether
Dimethyl Succinate
Dimethyl Glutarate
