Abstract
An intercomparison of sampling devices was onducted using sea water at 9 m. in a plastic enclosure of 65 m3 in Saanich Inlet, B.C., Canada. The sampling methods were (i) peristaltic pumping with teflon tubing, (ii) Niskin PVC sampler, (iii) Go-Flow sampler, (iv) Close-open-close sampler, and (v) teflon-piston sampler. Sampling was conducted for 4 days: Day 1 (2 August, 1978) for mercury, Day 2 for lead, cadmium, copper, cobalt and nickel by Chelex extraction and differential pulse polarography (D.P.P.) as well as manganese by Chelex and flameless atomic absorptiometry (F.A.A.), Day 3 for lead by isotope dilution and Day 4 for cadmium, copper, iron, lead, nickel and zinc by freon extraction and F.A.A. Samples were processed in clean rooms in the shore laboratory within 30 minutes of sampling. Results indicated the feasibility of intercalibrating using the enclosure approach, the availability of chemical techniques of sufficient precision in the cases of copper, nickel, lead and cobalt for sampler intercomparison and storage tests, a problem in subsampling from the captured sea water in a sampler, and the difficulty of commonly used samplers to sample sea water in an uncontaminated way at the desired depth.
