A piece of apparatus that consists of an ion source, a mass-to-charge analyser, a detector and a vacuum system and is used to measure mass spectra. The detector is a quadrupole mass-to-charge analyser, which holds the ions in a stable orbit by an electric field generated by four parallel electrodes.

Dissolved neodymium (Nd) isotopes and concentrations of rare-earth elements (REEs) reported by LDEO in seawater samples collected during the GEOTRACES GP16 East Pacific Zonal Transect cruise (TN303) on R/V Thomas G. Thompson from October to December 2013 | The preconcentrated REEs were measured on a VG PlasmaQuad ExCell® quadrupole ICP‐MS, which was coupled to a desolvating introduction system (a CETAC Aridusᵀᴹ) that minimized molecular oxide ion formation with a self‐aspirated Apex ST PFA micro flow nebulizer (ESI). For quality control, the LDEO lab repeatedly analyzes seawater samples from a GEOTRACES intercalibration station Bermuda Atlantic Time Series (BATS; 31.7°N, 64.1°W) in the North Atlantic at 20 m (n = 18) and 2,000 m (n = 16) (Wu et al., 2020). For the BATS 20 and 2,000 m samples, long‐term external reproducibilities (2σ RSD%) range from 1.5% to 6.2%, depending on the element, using a two standard deviation filter on the data (Wu et al., 2020).
