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 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...
متن کاملMinimization of sample volume with air-segmented sample injection and the simultaneous determination of trace elements by ICP-MS.
The application of inductively coupled plasma mass spectrometry (ICP-MS) to forensic chemistry was studied. The developed method, air-segmented sample injection (ASSI) coupled with ICP-MS, allowed the determination of about 25 elements at the sub-ppb level with only 0.2 ml of a sample solution. The optimum sample flow rate was found to be 0.4 ml min(-1), along with a sample suction time of 30 s...
متن کاملMultielement determination and speciation of major-to-trace elements in black tea leaves by ICP-AES and ICP-MS with the aid of size exclusion chromatography.
A multielement determination of major-to-trace elements in black tea leaves and their tea infusions was carried out by ICP-AES (inductively coupled plasma atomic emission spectrometry) and ICP-MS (inductively coupled plasma mass spectrometry). Tea infusions were prepared as usual tea beverage by brewing black tea leaves in boiling water for 5 min. About 40 elements in tea leaves and tea infusio...
متن کاملDetermination of Trace Elements in High Purity Tungsten by Solid-Phase Extraction/ICP-MS
To establish a rapid trace-quantification scheme for elements contained in highly purified tungsten, we studied the most suitable conditions for separating the elements using solid-phase-extraction as a pretreatment for inductively coupled plasma-mass spectrometry (ICP-MS). We used chemically bonded silica gels belonging to the functional group of benzylsulfonic acid as extracting agent. Tungst...
