This study reports on the development of an immunochromatographic flow-injection (FI) method for the quantitation of human serum IgG antibodies to Helicobacter pylori. Patients' sera were injected into the carrier stream of a FI manifold incorporating an H. pylori immuno-adsorbent reactor. The immuno-adsorbent was prepared by covalently linking H. pylori antigens to periodate oxidized Sepharose CL-4B...
A fluorimetric flow injection method is described for the quantitation of cyanide ions in aqueous media. The method is based on the isoindole fluorogenic adduct formed when o-phthalaldehyde reacts with taurine in the presence of CN - ions. Under optimized flow injection conditions (loop size, 130 μl; flow rate, 0.75 ml min -1 ; delay coil length, 0.4 m) linear calibration curves...
