Brief Method
Summary:
 Relies on the adsorption of target compounds on a SPME fiber. The fiber is placed in the headspace above the sample in a closed vessel and allowed to equilibrate with the aqueous sample. After equilibration time, the fiber is removed and inserted directly into the injection port of a GC or GC/MS system.
Scope And
Application:
 Taste- and odor-causing compounds: methyl isoborneol (MIB), geosmin, isopropyl methoxy pyrazine (IPMP)
Applicable
Conc Range:
 10 to 100 ng/L
Interferences: Any organic compounds present in the sample may be adsorbed onto the fiber and desorb in the GC/MS. The mass spectrum serves to identify the compound of interest and eliminate possible interferences.
QC Requirements: LCS, LFM
Sample Handling: Collect samples in either a single amber glass bottle of at least 250 mL or in two amber glass vials (minimum size 60 mL), preferably with no headspace.
Preserve sample with 10 mg mercuric chloride/L sample if it will not be analyzed within 3 d of sampling. Pack samples in ice and ship to laboratory for next-day delivery if they are not analyzed immediately. Store samples under refrigeration.
Max Holding Time:
 
Relative Cost: Greater than $400
