As the old adage goes, beauty is in the eye of the beholder. Ultimately, in the world of jewelry, the unwitting buyer uses his or her naked eye to decide which baubles are the most beautiful and worthy of wear. The expert jeweler and gemologist, howe

A high-efficiency nebulizer (HEN) and a demountable thimble glass frit nebulizer are evaluated for argon inductively coupled plasma-atomic emission spectrometry (Ar ICP-AES). Aerosol characteristics for the HEN and the thimble frit are studied using

Intensities and widths of atomic spectral lines of He, H, and Fe, excited in an atmospheric-pressure helium inductively coupled plasma (He ICP) were measured with a high-resolution Fourier transform spectrometer. These data along with measured intens

The differential electromobility technique was used for the comparison of droplet- and particle-size distributions in the 0.02–0.8 μm range for six nebulization systems often used in inductively coupled plasma (ICP) spectrometry: a thermospray neb

Dual-beam, light-scattering interferometry was used for simultaneous measurements of particle-size and particle-velocity distributions, size-velocity correlation, particle number density, and volume flux and span of desolvated aerosols. A commercial

The most commonly used solution nebulizers (1) in atomic spectrometry are: (a) pneumatic nebulizers (PNs), (b) ultrasonic nebulizers (USNs), and (c) glass frit nebulizers (GFNs). Most PNs are extremely inefficient because the majority of test solutio

A method was needed to conduct a 24-h intravenous infusion procedure in rabbits that minimized animal restraint and allowed unlimited access to the animal by research staff. We catheterized 16 male and 16 female New Zealand White rabbits (Oryctolagus

Noise power spectra (NFS) of helium inductively coupled plasmas (He ICPs) were measured using tangential- and laminar-flow torches. To identify the noise sources originating from the sample introduction systems and the plasmas, NPS were measured for
