“…The slurry 2.3% corresponded to the minimal concentration that allowed to the measurement of Zinc signal in the lower value of the working calibration range. The 12.5% is a concentration in the range recommended by Mohamed and Fry, 1981 for homogeneized tissues and 23.5% corresponds to the critical matrix due to the high solid content. The stability of the absorbance signal does not depend on the acid at concentration levels lower than 12.5%, evidencing that the analyte is mostly in the aqueous phase.…”

“…The analysis by FAAS of solid samples or high solid content samples, as could be crude clinical samples is not frequently found in the literature. It is reported the use of slurries from crude tissues combining the FAAS technique with nebulization with a Babington type nebulizer for the introduction of high solids content samples (Mohamed and Fry, 1981;Fry and Denton, 1977). Brandao et al, 2011 reported a simple and fast procedure for the sequential multi-element determination of Ca and Mg in dairy products employing slurry sampling and high resolution-continuum source flame atomic absorption spectrometry (HR-CS FAAS).…”

“…The use of discrete nebulisation instead of continuous aspiration of the sample, by means of flow injection, decreases the possibility of nebuliser clogging 18 . Thus, under appropriate conditions, the flame atomisation of slurries can be successfully used with different kinds of materials, as described in the literature [19][20][21][22] .…”

“…[16][17][18][19][20][21] In order to solve these problems related to the transport efficiency of the suspended particles in the slurry, some authors proposed the use of special nebulizers. [22][23][24][25] Krill (Euphasia superba) is a small shrimp extremely abundant in the Southern Ocean that can vary in length from less than 1 cm to ca. 15 cm, being mostly transparent, with large black eyes, a brught red shell, and often a vividly green stomach, but it becomes curled up and opaque when dead.…”
