Sample introduction valve used in ICP-AES for faster analysis
A twin six-port valve with two sample loops was installed between the autosampler and the nebuliser of a simultaneous inductively coupled plasma-atomic emission spectrometer. The valve was mounted close to the nebuliser inlet so that the time required for the sample to enter from the loop to the nebulizer was less than 0.5 s. The content of one loop was introduced to the nebulizer using a peris...
متن کاملThe Analysis of Ecstasy Tablets by Icp/ms and Icp/aes
In this study, tablets coming from different police seizures (in Switzerland) were analysed by ICP/MS and ICP/AES. Two methods of preparation were carried out in order to compare the influence of sample preparation. 25 elements were screened by ICP/AES whereas most of the periodic table could be screened by ICP/MS. Approximative detection limits were determined for most of the elements showing,...
متن کاملMajor-to-ultratrace elements in bone-marrow fluid as determined by ICP-AES and ICP-MS.
The major-to-ultratrace elements in human bone-marrow fluid were determined by ICP-AES (inductively coupled plasma atomic emission spectrometry), and ICP-MS (inductively coupled plasma mass spectrometry). The bone-marrow fluid sample was centrifuged prior to acid digestion to exclude the bone piece from bone marrow, and then digested with nitric acid. As a result, 20 elements could be determine...

متن کاملLow-pressure ICP-AES with electrothermal vaporizer and a pneumatic nebulizer for aqueous sample introduction.
A typical electrothermal vaporization (ETV) using a tantalum was built for low-pressure ICP-AES. The analytical performance of the ETV was tested and compared with that of a PFA pneumatic nebulizer with a double membrane desolvator (DMD). The limits of detection of the ETV were obtained in the range of 3.4 ng to 758 ng for Zn, Cu, Co, Fe, and Mg, while those of the PFA nebulizer were in the ran...
