Laser ablation inductively coupled plasma mass spectrometry assisted insight into ion-selective membranes.

Agata Michalska et al.

Analytical chemistry, 78(15), 5584-5589 (2006-08-02)

Laser ablation inductively coupled plasma mass spectrometry was used to evaluate ion depth profiles across ion-selective membranes. Advantageously, this approach does not require incorporation of additional components (e.g., chromoionophore) in the membrane composition, as compared to that used in typical

Experimental evaluation of oil mists using a semivolatile aerosol dichotomous sampler.

Seung Won Kim et al.

Journal of occupational and environmental hygiene, 7(4), 203-215 (2010-02-05)

The sampling performance of the semivolatile aerosol dichotomous sampler (SADS) was tested and compared with existing vapor and particle sampling methods: filtration, electrostatic precipitation, and vapor adsorption. Seven different test fluids were used to generate test droplets, and their concentrations

Comparability of portable nanoparticle exposure monitors.

Christof Asbach et al.

The Annals of occupational hygiene, 56(5), 606-621 (2012-07-04)

Five different portable instrument types to monitor exposure to nanoparticles were subject to an intensive intercomparison measurement campaign. Four of them were based on electrical diffusion charging to determine the number concentration or lung deposited surface area (LDSA) concentration of

Sensitive and selective detection of trace copper in standard alloys, food and biological samples using a bulk optode based on N,N'-(4,4'-ethylene biphenyl) bis(3-methoxy salicylidine imine) as neutral carrier.

Majid Arvand et al.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 107, 280-288 (2013-02-26)

In this paper, an optical sensing film has been proposed for sensitive determination of copper (ІІ) ion in aqueous solutions. The copper sensing membrane was prepared by incorporating N,N'-(4,4'-ethylene biphenyl) bis(3-methoxy salicylidine imine) as ionophore in the plasticized PVC membrane

Developing ultra-high gas permeance PVDF hollow fibers for air filtration applications.

Bereczki, R.,

Analytical Chemistry, 569, 42-42 (2006)

Intersubject variability in particle deposition does not explain variability in responsiveness to methacholine.
