performed by QA personnel independent of direct responsibility for the verification test. All
implementation activities were documented and are traceable to the Test/QA plan and to test
personnel.
The main component to the QA plan included technical systems audits (TSA) conducted
by an ACT Quality Assurance Manager of the laboratory tests at MLML and of the field test in
Baltimore Harbor to ensure that the verification tests were performed in accordance with the test
protocols and the ACT
Quality Assurance Guidelines
. All analytical measurements were
performed using materials and/or processes that are traceable to a Standard Reference Material.
Standard Operating Procedures were utilized to trace all quantitative and qualitative
determinations to certified reference materials. Lastly, ACT’s QA Manager audited
approximately 10% of the verification data acquired in the verification test to assure that the
reported data and data reduction procedures accurately represented the data generated during the
test.
RESULTS of LABORATORY TEST
Laboratory tests of response factor, precision, range, and reliability were conducted at
Moss Landing Marine Lab utilizing five different challenge compounds covering a range of
fluorescent properties (see Table 1 above) to facilitate comparisons against the range of optical
detection windows utilized by participating hydrocarbon sensors. Tests were performed in
insulated 500 L, black acrylic tanks in a dark room using filtered deionized water (DI) as the
background medium (Photo 1). Reference samples of these challenge compounds were
characterized and quantified using EEMS on a FluorMax-2 (photo 2) over a range of
concentrations from 0 – 5000 ppb (nominally 0, 1, 5, 10, 50, 100, 500, 1000, 5000 ppb).
