“…Applications of C 4 D without electrophoretic or chromatographic separation include flow injection analysis (FIA) , SI analysis , and other methods operating with liquid or even gaseous flows. FIA was also used in the testing of C 4 D on a microfluidic device using simple salt solutions at different concentrations .…”

“…The same concept of gas diffusion coupled to FIA‐C 4 D was used for determination of dissolved inorganic carbon in environmental water samples . A reagent‐free SI analysis method for CO 2 determination in soft drinks was described by Teerasong et al . Aqueous droplets of a saline solution were detected based on their higher conductivity in a segmented flow of an organic solvent .…”

The developments in the field of capacitively coupled contactless conductivity detection in the approximate period from July 2010 to June 2012 are traced. Few reports concerning fundamental studies or new detector designs have appeared. On the other hand, applications in standard CZE are flourishing and contactless conductivity measurements are increasingly being employed as part of novel or more sophisticated experimental systems. Work on the lab-on-chip devices integrating contactless conductivity detection is continuing. A range of reports on the use of the simple yet powerful detection technique of contactless conductivity measurements in chromatographic separation as well as for analytical methods not including a separation step have also appeared.

“…If a scheme can be devised that will permit continuous flow of both donor and acceptor streams without contact but in close vapor phase communication (in principle, much the same as a flow-through Conway cell) then the need for the membrane in the pervaporation arrangement will be obviated. Both Choengchan et al [40] and Mornane et al [41] independently accomplished this; the former group has since carried out other work on such “membraneless” vaporization or gas diffusion [42–45]. …”

Deaths due to smoke inhalation in fires are often due to poisoning by HCN. Rapid administration of antidotes can result in complete resuscitation of the patient but judicious dosing requires the knowledge of the level of cyanide exposure. Rapid sensitive means for blood cyanide quantitation are needed. Hydroxocyanocobinamide (OH(CN)Cbi) reacts with cyanide rapidly; this is accompanied by a large spectral change. The disposable device consists of a pair of nested petri dish bottoms and a single top that fits the outer bottom dish. The top cover has a diametrically strung porous polypropylene membrane tube filled with aqueous OH(CN)Cbi. One end of the tube terminates in an amber (583 nm) light emitting diode; the other end in a photodiode via an acrylic optical fiber. An aliquot of the blood sample is put in the inner dish, the assembly covered and acid is added through a port in the cover. Evolved HCN diffuses into the OH(CN)Cbi solution and the absorbance in the long path porous membrane tube cell is measured within 160s. The LOD was 0.047, 1.0, 0.15, 5.0 and 2.2 μM, respectively, for water (1 mL), bovine blood (100 μL, 1 mL), and rabbit blood (20μL, 50 μL). RSDs were < 10% in all cases and the linear range extended from 0.5 to 200 μM. The method was validated against a microdiffusion approach and applied to the measurement of cyanide in rabbit and human blood. The disposable device permits field measurement of blood cyanide in < 4 min.

“…The flow analysis coupled with membraneless format has been developed [17][18][19]. Air segmentation in such systems can have advantages [20]; this has been applied to ethanol determination [21].…”
