TL;DR: In this paper, a flow injection system with spectrophotometric detection was proposed for determining N-acetyl-L-cysteine in pharmaceutical formulations, and the linearity of the calibration curve for Nacetyl L-Cysteine ranged from 3.5×10-6 to 4.3×10 -4 M.
Abstract: A flow injection system with spectrophotometric detection is proposed for determining N-acetyl-L-cysteine in pharmaceutical formulations. In this system, N-acetyl-L-cysteine was oxidized by Fe(III) and the Fe(II) producedis spectrophotometrically monitored as Fe(II)-1,10-phenantroline complex at 510 nm. Under the optimum analytical conditions, the linearity of the calibration curve for N-acetyl-L-cysteine ranged from 3.5×10 - 6 to 4.3×10 - 4 M. The detection limit of 6.3×10 - 7 M and recoveries between 98.5 to 110% were obtained.

TL;DR: In this paper, a proof is given that a recently introduced univariate presentation of a multivariate calibration model is exact, i.e., there are no approximations involved.

TL;DR: A method has been developed using high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GFAAS) for direct determination of arsenic in solid soil samples and the modifier that showed the best results was the Zr, used as a permanent modifier.

TL;DR: In this paper, the contents of several oxides, such as Fe2O3, CaO and MgO, in geological samples from the Tierga Mine (Zaragoza, Spain) were analyzed by LIBS.
