An open/closed flow system allowing variable volumes of both sample and standard calibration solution to be introduced was employed to perform automatic calibration in unsegmented flow systems by using the method of standard additions. The dilution loop thus established was used to homogenize the sa
An on-line flow injection sample to standard addition method was developed for the determination of aluminium in biological tissues by inductively coupled plasma mass spectrometry. The sample concentration is calculated from two transient signals obtained from the injection of the blank and the samp
The coupling technique of synchronous fluorimetry and the H-point standard additions method was applied to determine cephalexin and cefadroxil with symmetric and seriously overlapping spectra simultaneously. Under the optimum conditions, the linear determination ranges of cephalexin and cefadroxil a
