Bacteriological evaluation of an ultra-pure water-distilling system.
A prototype distillation and storage system with recycle for producing ultrapure water was monitored for bacteriological contamination during a period of 24 months. Naturally occurring Pseudomonas aeruginosa and P. cepacia were found to grow rapidly to levels of about 10(5)/ml in water taken from the storage reservoir and also in commercially prepared distilled water. The system was found to el...
متن کاملComparison of immittance spectroscopy analyses of ultra-pure and “pure” water in the lower frequency regime
Two different analyses of impedance data obtained from ultra-pure water allowed to equilibrate with the atmosphere have recently appeared. They both thus show much smaller low-frequency resistances than does ultra-pure water. Different fitting models were used in these analyses and led to appreciably different parameter estimates from their data fits. Their two “pure” water experimental data se...
متن کاملUltra-pure, water-dispersed Au nanoparticles produced by femtosecond laser ablation and fragmentation
Aqueous solutions of ultra-pure gold nanoparticles have been prepared by methods of femtosecond laser ablation from a solid target and fragmentation from already formed colloids. Despite the absence of protecting ligands, the solutions could be (1) fairly stable and poly size-dispersed; or (2) very stable and monodispersed, for the two fabrication modalities, respectively. Fluorescence quenchin...
متن کاملRaman scattering by pure water and seawater.
Measurements of the magnitude and spectral distribution of the Raman-scattering coefficients of pure water (b(rw)) and seawater (b(rs)) are presented. Two independent measurements of the spectral distribution of the Raman-scattering coefficient of pure water were made for incident wavelengths ranging from 250 to 500 nm. These measurements revealed a strong dependence of b(rw) on wavelength that...
متن کاملSerious contaminant in "ultra pure" grades of sucrose.
might account for the apparent absence of stretch reflexes at expected latencies in human subjects reported by several investigators (10). The pause between a monosynaptic response to stretch and a later increase in electromyographic activity may be due to a preponderance of inhibition from Golgi organs, as has been suggested for the respiratory system (11). Preliminary results with standing hu...
