Brief Method Summary
|
An aqueous liquid waste or TCLP leachate is directly injected into a reverse-phase high performance liquid chromatography (HPLC) column and are eluted and detected using ultraviolet (UV) absorbance. Components are identified by their retention time on the primary column and are confirmed by either their UV-visible spectrum or their retention time on the secondary column. |
Scope and Application
|
This method determines the toxicity characteristics leaching procedure (TCLP) acidic semivolatile compounds and certain herbicides in leachates and aqueous liquid-waste samples. |
Applicable Concentration Range
|
0.5 - 350ug/L* (* Limits differ for each compound. This range is taken from the lowest and highest limit of the compounds listed in the method.) |
Interferences
|
(A) UV-absorbing compounds: UV-absorbing compounds that co-elute with target analytes can interfere. (B) Alkalinity: Highly alkaline samples may degrade target analytes or interfere with chromatographic separation. |
Quality Control Requirements
|
Example QC requirements are outlined in EPA SW-846 Methods. |
Sample Handling
|
Sample collection, preservation, and handling should be addressed in the planning process. |
