“…McDonald et al (194) reviewed the developments and applications in field mass spectrometers including advantages of the analytical methods of field, gas chromatography, and chromatography/mass spectrometry. They have compared the data taken on land and in laboratory of biphenyl polychlorates and aromatic polycyclic hydrocarbons in different locations.…”

“…The HP 5971AMSD relies on linear quadrupole-configured magnets to differentially accelerate the various (charged) masses through a long path and then relates that differential to the molecular (or fragment) mass using a reference. The ion trap detector differs from a linear quadrupole detector in the manner of obtaining the mass information [9,15]. The ion trap is a three-dimensional quadrupole cavity in which the various (charged) masses are brought into resonance with a scanning radiofrequency energy and discharged from the cavity; the resonance discharge pattern is the information that can be related to mass.…”

“…Because financial resources for remedial activities are limited, the question of relative cost versus the value of added information is becoming increasingly more important [10,11]. The cost of on-site analytical techniques using these new technologies compared to the cost of using stationary, commercial analytical laboratories is an important issue to investigate when developing sampling and analysis plans [12][13][14][15]. Studies that address the issue of cost and demonstrate that both significant cost savings and acceptable data quality objectives are indeed possible, are a significant step toward finding the most cost-effective ways to accomplish remediation goals.…”

This paper examines the cost and performance characteristics of six different field analytical instruments capable of accurately identifying and quantifying volatile organic compounds (VOCs) at the parts-perbillion level. Five-year life-cycle costs for the six field instruments including purchase, modification, and operational costs, were compared to the costs of using a stationary commercial analytical laboratory to obtain identical VOC data. The present-value life-cycle cost of a single soil or water VOC analysis was calculated for the six field alternatives and for the commercial laboratory at both a fixed annual sample analysis rate and at maximum capacity. The total cost of a single field analysis event was found to be approximately 18% of the total cost of sending that sample to a commercial laboratory. Cost differences between alternatives were correlated to variations in performance capabilities. 2269

“…Of the field transportable GCIMS systems available, the SpectraTrak GCIMS was chosen and purchased because it is capable of powerful analyses in both field or laboratory use (McDonald et al 1994). To provide complete remote capability for the GCIMS, a small 2.4-KVA generator was also purchased.…”

The Effluent Monitoring Program characterizes and monitors liquid waste streams from 300 Area buildings owned by the U.S. Department of Energy and managed by the Pacific Northwest labor at or^.'^' This program is managed by the Pacific Northwest Laboratory. This report summarizes the results of characterizing and monitoring the following sources during calendar year 1994 (the first year of the program): liquid waste streams from Buildings 306, 320, 324, 326, 331, and 3720; treated and untreated Columbia River water (influent); and water at the confluence of the waste streams (that is, end-of-pipe). Data were collected from March to December before the sampling system installation was completed. Data from this initial part of the program are considered tentative.Concentrations and clearance times at end-of-pipe were highly dependent on waste stream flow rates, dispersion, and the mechanical action of sumps. When present, the sumps had the greatest impact on clearance times. In the absence of sump activity, dispersion and flow rate were the controlling factors.Initial evaluations of field transportable gas chromatography/mass spectrometry, adsorptive stripping voltametry, solid phase extraction, and continuous monitoring of flow, pH, and conductivity were favorable. These technologies illustrated the highly variable nature of the effluent streams and the potential to improve current characterization practices.
