NexION 300 ICP-MS*1

Location: 209 Schrenk Hall

NexION 300 ICP-MS*1 209 Schrenk Hall A bench top ICP-MS with single nanoparticle (SP)-ICP-MS function was obtained from PerkinElmer.

Elan DRC Inductively Coupled Plasma-Mass Spectrometer (ICP-MS)

Location: 209 Schrenk Hall

A model Elan DRC Inductively Coupled Plasma-Mass Spectrometer (ICP-MS) was purchased from PerkinElmer. There are three different sample introduction systems for this instrument, a model ASX-510 liquid autosampler (CETAC Technologies product) for general aqueous sample introduction, a model UP213AS laser ablation system (NewWave product) for solid sample introduction, and a model Series 200 high performance liquid chromatography (HPLC) sample separation/introduction system (PerkinElmer product) for speciation analysis (such as different species of arsenic, selenium, chromium, iodine compounds, bromine compounds and more). This instrument is mainly used for trace to ultra-trace level (part per billion to part per trillion concentrations) metal and semi-metal elements analysis
