Availabilities of ICP-AES Analysis with a Ultra-Sonic Nebulizer for Environmental Water Samples.

Low-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...

Ultra-Trace Analysis of Beryllium in Water and Industrial Hygiene Samples by ICP-MS Application

Exposure to airborne beryllium can lead to adverse health effects in humans. Consequently, many countries have legislation in place to ensure the health and safety of workers and the wider environment. Because even very low concentrations of Be in air constitute a toxic threat to health, analytical methodology that is capable of extremely high-sensitivity measurement is required. Although trace...

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...
