In the work described, almost all of the elements present in lake or river waters at concentrations of one part in 10 11 parts of water and higher were routinely determined. In the particular waters investigated 30 or more elements were found in each sample. The main features of the ...
A new atom identification and detection technique for ultrasensitive mass spectrometry has been applied to the radionuclide 36Cl. Measurements of the 36Cl/Cl ratio in AgCl precipitated from six different natural water samples fell in the range 1.2 × 10
On-column trace enrichment and liquid chromatography using a single short (20 mm length) high-pressure packed column was optimized for the rapid simultaneous identification and quantification of a wide range of organic microcontaminants in environmental water samples. The quality of different C 18 bond...
3) environmental water 环境水样 1. A rapid,simple,accurate and sensitive online method was proposed to determine sulfide in environmental water based on the combination of methylene blue spectrophotometryand automatic reference Flow Injection Analysis(FIA) without procedure of H_2S absorption. 利用亚...

These are classical VOCs that are seen in a variety of sample types. In this analysis of groundwater, they used a polar (wax) column in the first dimension and then transferred heart-cuts to a nonpolar (5% phenyl polydimethylsiloxane) column in the second dimension. As seen in Fig. 8.4A...
Murine norovirus and mengovirus were also quantified in our MFQPCR system as a sample processing control and an internal amplification control, respectively. River water contaminated with effluents from a wastewater treatment plant in Sapporo, Japan, was collected and used to validate our MFQPCR ...
