Nonsuppressed single-column ion chromatography (SCIC) was introduced in 1979 by Gierde and coworkers, based on a two-principal innovation ... [Pg.860]

In single-column ion-exchange chromatography, analyte ions are separated on a low-capacity ion exchanger by means of a low-ionic-strength eluent that does not interfere with the conductometric detection of analyte ions. [Pg.988]

Single-column ion chromatography offers the advantage of not requiring special equipment for suppression. It is a somewhat less sensitive method of determining anions than are suppressor column methods, however. [Pg.988]

Electronic suppression is possible if the eluent is properly chosen for extra-low conductivity which is e.g. the case with phthalate buffers. The detector must be able to compensate for the background conductivity by its electronics. Such a set-up gives good calibration linearity over a wide range but its detection limit is rather poor. For historical reasons it is also termed single-column ion chromatography. [Pg.226]

By choosing an eluent that does not dissociate strongly it is possible to eliminate the suppressor column. Such compounds as phenol, pK, = 1.3 x 10 , or phthalic acid, K, = 1.3 x 10 K,2 = 3.9 x 10, are examples. When compounds of this type are used the system is called single column ion chromatography (SCIC). Table 24-2 lists some of the other common eluents for anions. [Pg.279]

The dual-column and single-column ion-exchange precoilcentration flame AAS systems as well as the DDC-Cis sorbent extraction flame AAS and ETAAS systems used for the determination of cadmium were also used for the determination of copper in water samples. The detection limit for the dual-column system was 0.07-0.09 /ig l at 60 samples h [7] for the sorbent extraction preconcentration flame AAS system, 0.2 /xg r at 120 samples h [9] for the sorbent extraction ETAAS system, 0.02 /xg 1 at approximately 20 samples h [10]. The sensitivity of sorption column preconcentration methods with flame AAS detection should be sufficient for the determination of copper in most natural water samples. [Pg.200]
