Abstract
Inductively coupled plasma mass spectrometry (ICP-MS) is widely used when rapid and sensitive detection for a wide range of elements of airborne particles is required in many situations, such as the monitoring of the ambient particulate matter (PM), emission sources, and the clean room air for semiconductor manufacture processes. For on-line and real-time analysis of aerosol samples using ICP-MS, the gas exchange devices (GED) which followed by the replacement of air with argon and transported to the ICP-MS is need to be equipped due to sustaining the plasma. However, the ICP-MS used a quadrupole mass spectrometer (ICP-QMS), a detailed study on the signal fine structure with scanning-based mass spectrometers but no simultaneous multi-element measurement was possible. In order to further improve time resolution of the ICP-QMS and to extend its capabilities to determine single particle information, ICP-MS equipped with the Time-of-Flight Mass Spectrometer (ICP-TOFMS) was developed recently. This study presents for application of real-time measurement for elements in particles using ICP-TOFMS. This technique is allowed to detect of engine oil additive elements in gasoline vehicle exhaust particles.
