Method 8265: [PDF Format 158
KB]
This method uses direct
sampling ion trap mass spectrometry (DSITMS) for the rapid quantitative
measurement, continuous real-time monitoring, and qualitative and quantitative
preliminary screening of volatile organic compounds (VOCs)
in water, soil, soil gas, and air. DSITMS introduces sample materials directly
into an ion trap mass spectrometer by means of a simple interface (such as a
capillary restrictor). There is little if any sample preparation and no
chromatographic separation. The response of the instrument to analytes in a
sample is nearly instantaneous. In addition, the instrument is field
transportable, rugged, and relatively easy to operate and maintain. Method
5035A: [PDF Format 197 KB] Closed-System Purge-and-Trap
and Extraction for Volatile Organics in Soil and Waste Samples
This method describes a
closed-system purge-and-trap sample preparation process for the analysis of
volatile organic compounds (VOCs) in solid materials
(e.g., soils, sediments, and solid waste). While the method is designed for use
on samples containing low levels of VOCs, procedures
are also provided for collecting and preparing solid samples containing high concentrations
of VOCs and for oily wastes. In addition, the method contains
an appendix with pertinent information and appropriate references based on
EPA's evaluation of currently available data and technology as applied to the
most appropriate sample handling and preservation procedures in order to
minimize the loss of VOCs during the collection and
analysis of aqueous and solid materials, such as groundwater, wastewater,
soils, solid waste, or sediments. These procedures are designed to minimize the
losses of VOCs through the two most common
mechanisms, volatilization and biodegradation. PROPOSED UPDATE IIIB EPA is proposing to revise several methods and chapters of SW-846 and release these revisions as an update (Update IIIB) to the Third Edition of SW-846Update IIIB is now available. Proposed Update IIIB is now available on-line.
Draft Update IVB
was issued by the EPA's Office of Solid Waste and contains methods which are
being considered for inclusion in SW-846. All Update IVB documents can be
viewed or downloaded from this site. View
the Federal Register notice (65 FR 70678) which announces Draft
Update IVB and explains the appropriate use of its methods or view the index
to the docket. To summarize:
UPDATED ARTICLE ON THE STATUS OF THE RCRA PROGRAM To find out more information about the current status of the RCRA methods development program, please look at the article "An Update of the Current Status of the RCRA Method Development Program". This article has been updated to include the activities of the OSW Methods Team in advancing the RCRA Methods Development Program over the past year. METHODS 9070A AND 9071B FOR OILY WASTE DETERMINATION OSW has revised the existing Methods 9070 and 9071A to replace the CFC Freon
113 with n-hexane as the extraction solvent for determination of oil and
grease. This change has been issued as a Direct Final Rule, which was published
in the Federal Register on SW-846 documents: The much awaited arrival of the SW-846 METHODS ON-LINE is now a reality. The documents found on-line are complete copies of the published versions and thus include all figures and tables. The files are retrievable in the Portable Document Format (PDF).
