1/6/2018 For sample collection in deep water (lakes), researchers have relied on various kinds of bailers (Kemmerer, Van Dorn, and double check-valve bailer) and thief samplers . Depending upon the depth of the water body, either a portable sampler (for shallower water) or a cable-and-reel sampler (for very deep reservoirs) can be used.

However, the 600 ug/L individual aliquots exceeded the calibration range of the instrument, and so these aliquots were diluted 1:3 (sample:reagent water) prior to analysis. The low concentration spiking scheme for each aliquot is shown in Table 2.

To reduce carry-over, the purging device and sample syringe must be rinsed with reagent water between sample analyses. Whenever an un- usually concentrated sample is encountered. it should be followed by an analysis of rea- gent water to check for cross contamination.

1/1/2020 For example, radon can be prepared for analysis by simply shaking a sample of water with a water-immiscible cocktail. However, the use of conventional LSAs does not preclude McDowell''s methods. Finally, these instruments also allow the use of an α-emitting isotope as a yield tracer in the analysis of a β-emitting isotope and vice versa (e.g., Pates et al., 1996b ).
