Mass spectrometry systems have specific vacuum requirements. New developments in oil-free, or dry, primary vacuum pumps have been introduced recently and are discussed in this article with respect to capacity, throughput, and specific pumping requirements for process gases.
This article discusses the key components of a typical liquid sample introduction system for inductively coupled plasma spectroscopy, and offers troubleshooting tips for problems commonly encountered by practitioners.
Through symposia, posters, and workshops, representatives from industry and academia addressed a broad range of technology and implementation issues that are beginning to change the landscape of modern spectroscopy.
This paper describes how analysts at an environmental and geochemical laboratory utilize dynamic reaction cell ICP-MS technology to study the transport and deposition of important trace metals from rainwater.
