Borsini E, Ernst G, Blanco M, Blasco M, Bosio M, Salvado A, Nigro C.
PMID: 28966736
Sleep Sci. 2017 Jan-Mar;10(1):35-40. doi: 10.5935/1984-0063.20170006.

INTRODUCTION: Patients that started on Non-Invasive Ventilation (NIV) need to define several parameters selected on the basis of diurnal arterial blood gas and underlying disease. We hypothesize that respiratory polygraphy (RP) could be useful to monitor NIV. This retrospective...

PMID: 11221921
Fresenius J Anal Chem. 2000 Aug;367(7):601-13. doi: 10.1007/s002160000422.

A thorough review of the literature published (1983 - March 1999) on chromium speciation in liquid samples is presented, and analytical techniques used in the 404 articles are summarized. The discussion focuses on atomic spectrometric techniques, which are mainly...

Chromium speciation using activated alumina microcolumns and sequential injection analysis-flame atomic absorption spectrometry.

Marqués MJ, Morales-Rubio A, Salvador A, de la Guardia M.
PMID: 18968217
Talanta. 2001 Mar 16;53(6):1229-39.

A new procedure has been developed for chromium speciation in water by sequential injection analysis and flame atomic absorption spectrometry. The method involves the online retention of Cr(VI) anionic species and Cr(III) cationic species on alumina microcolumns, prepared by...

Supercritical fluid extraction of resveratrol from grape skin of Vitis vinifera and determination by HPLC.
