Kiel in situ pump

The improvement in water sampling techniques such as the development of the Kiel in-situ Pump (KISP) [122] and high resolution gas chromatography (such as MDGC-ECD) has resulted in a series of papers on the concentration of di-, mono-, and occasionally non-ortho CB levels in world waters. This is detailed in Table 4. 

In situ filtration is reviewed briefly in Chapter 2 (Section 2.1.3.3). Here we outline the procedure for the collection of suspended particulate TE with the Kiel in situ Pump (KISP) introduced by Petrick et al. (1996) and also technically described in Chapter2 (see Fig. 2-2). The system has been developed primarily for the determination of organic compounds at ultra-trace levels (see also Chapter 22). 

The Kiel in situ pump system (KISP) for filtration and extraction of trace organics at the depth of sampling Petrick et al, 1996) is suitable for volumes of up to 2000 L or more (depending on particle concentration) and depths in excess of 6000 m. Sufficient amounts of PAH and CB may thus be collected in open-ocean waters to allow their analytical determination at concentration levels around or below 0.01 pg/L. The sampler is depicted in Fig. 22-1 (technical details can be found in Chapter 2).
