A status report on helium inductively coupled plasma mass spectrometry

“…With two exceptions, the instrumentation used in this work is similar to that described elsewhere [24,25,55]. First, in addition to the original mechanical pump (33-m 3 /h) used for the Ar ICPMS interface [55], a second mechanical pump (a 96-m 3 /h pump, Edward High Vacuum International, Wilmington, MA) was installed on a separate port for the ICPMS interface.…”

Sample introduction systems for the analysis of liquid microsamples by ICP-AES and ICP-MS

“…Porous [161,162] as well as non-porous [163,164] fluoropolymer membrane is set up at the chamber exit. A sweep argon stream is Eliminado: Figure 13 introduced to remove the solvent vapour.…”

Evaluation of an Ultrasonic Nebulizer Interface for Capillary Electrophoresis and Inductively Coupled Plasma Mass Spectrometry

“…This improvement is due to the increased analyte transport to the plasma resulting from the initial production of a dense aerosol with smaller droplets than those from pneumatic nebulizers (PNs) (32,33). When both USN and PN are used with desolvation, the USN improves detection limits by a factor of 3-8 over the PN (34). Therefore, an ultrasonic nebulizer is chosen as an alternative for the CE-ICP-MS interface.…”
