High Uptake Rate Radial Diffusive Sampler Suitable for Both Solvent and Thermal Desorption

Biological indices of kidney involvement in personnel exposed to sevoflurane in surgical areas

“…Exposed subjects were monitored throughout the surgical session by means of Radiello 1 [Cocheo et al, 1996] passive samplers; the samplers were then eluted in a water/methanol (60/40, v/v) mixture, and the anesthetics were determined by chromatographic methods and mass spectrometry (analytical conditions were for SEV: ion mass monitored ¼ 31, 69, 131, and 181; dwell time ¼ 0.2 s; multiplier ¼ 300 V; for N 2 O: ion mass monitored ¼ 44; dwell time ¼ 0.2 s; multiplier ¼ 300 V) Spot urine samples were obtained at the end of operating sessions to assay N 2 O (N 2 OU) by means of head-space gaschromatographic analysis with an ECD detector (autosystem XL) and SEV (SEVU) by means of gas-chromatography and mass-spectrometry. Analytical conditions of massspectrometry were: ion mass monitored ¼ 31, 69, 131, and 181; dwell time ¼ 0.2 s; multiplier ¼ 400 V. In addition, total urinary proteins (TUP) according to Pesce and Strande [1973], N-acetyl-b-D-glucosaminidase (NAGU, E.C.…”

Risk assessment of sensory irritants in indoor air—a case study in a French school

“…Aldehydes: Passive sampling devices (Radiello®, Fondazione Salvatore Maugeri, Padova, Italy (Cocheo et al, 1996)) equipped with dinitrophenyl hydrazine (DNPH) sampling cartridges and ozone scrubbers (Bates et al, 2000), were used to quantify concentrations of the compounds listed in Table 1. After exposure, the sampling cartridges were extracted with 2 ml acetronitrile. The extracts were analysed with HPLC separation (KROMASIL C18 150 mm-3mm -3.5 (im) and UV detection (k=365 nm).…”

A Field Method for Sampling Toluene in End-Exhaled Air, as a Biomarker of Occupational Exposure: Correlation with Other Exposure Indices.

“…The breath sampler (Fig. 2) consisted of a 58 mL glass vial containing an adsorbing cartridge (60 mm × 3.9 mm) built with stainless steel net (Radiello, Fondazione S.Maugeri, Padova, fsmpd@fsm.it, Italy) 15) and filled with 300 mg Tenax TA ® (35-50 mesh) which had been previously thermally desorbed for 30 min at 240°C under nitrogen flow to ensure maximum purity, and closed with Teflon rubber lined septa and hole caps. The alveolar air was collected in these vials containing the Tenax cartridge, then the vials were immediately sealed.…”
