|This one-day short course will address the application of ICP-AES and ICP-MS for compliant analysis of water, wastewater and related solid wastes using USEPA 200.5, 200.7, 200.8, SW 846 6010C, and 6020A
These procedures will be evaluated using QA/QC criteria and figures of merit such as IDLs, MDLs, LLCV, LLICV, CCV, ICV, LDRs, recovery from spiked matrix solutions and CRMs. This course will provide an insight to practical water and waste sample analysis highlighting sampling strategies, sample preparation, instrumentation, spectroscopic and nonspectroscopic interference effects and validation.
The course will commence with a brief overview of sample collection and chain of custody procedures, sample preservation, holding times, and containers.
Sample preparation schemes provided by USEPA (filtration, open vessel and microwave digestion) will be described and their efficiencies compared using recovery, contamination, sample throughput, and cost.
Instrumentation will be reviewed - axial vs. radial CCD and CID ICP-AES and Collision vs. Reaction cells ICP-MS.
Instrument setup and optimization routines will be described.
Emphasis will be placed on nonspectroscopic interference effects associated with sample introduction, the plasma, plasma-MS interface, and spectroscopic interferences, such as spectral overlap in AES and polyatomic ions in MS. Methods for their correction and compensation will be presented.
ISO 17025 accreditation and analytical uncertainty will be addressed and the question of EPA procedures meeting requirements of ISO 17025 evaluated
