“…Although continuous-sample furnaces have these advantages, Winefordner and Veillon report detection limits for AAS (31,34) and AFS (35) which are approximately the same as those obtained in the corresponding flame techniques. The main disadvantage with continuous sample introduction is that of sample dilution by the carrier gas, which decreases the analyte concentration in the light path.…”

“…A few of Woodriffs results appear in Table 4. Molnar and Winefordner have described a continuous sample introduction graphite furnace for use in atomic fluorescence (31). This two chamber furnace consists of a desolvation chamber where the sample is introduced as a fine aerosol, and a heated vitreous carbon tube where the desolvated sample is atomized.…”

“…The various gases (nebulization Ar, desolvation CH4, and the Ar-Ha diffusion flame sheath) were flowing continuously. The temperatures of the vitreous-carbon tube and desolvation chambers were independently adjusted by varying their respective currents (9). The desolvation chamber was adjusted so that the exiting gases attained a temperature of 250 °C.…”

“…When automatic procedures of sample introduction are sought for the carbon rod atomizer in atomic spectrometry three requirements should be met: i) small sample volumes (1)(2)(3)(4)(5) µ ); ii) critical sample positioning (narrow strip of graphite); iii) absence of containing walls. The concomitance of these three requirements rules out solutions such as those proposed by Pickford and Rossi (1) (too large a volume injected: 100 µ ) or by Molnar and Winefordner (2) (graphite tube acting as container for the nebulized sample). Maessen et al (3) used a commercial syringe (S.G.E.)…”
