LA-ICP-MS Lab

Facility	LA-ICP-MS lab (iCRAG@TCD)
Bookings and enquiries	iCRAG-ICP@tcd.ie
Booking form	Application to work in LAICPMS lab
Staff	Dr. Sean McClenaghan
Research Assistant	Gary O'Sullivan
Location	Unit 7, Trinity Technology And Enterprise Centre (TTEC), Pearce Street.
Instrument	Photon machines G2 193nm UV laser with a Helex two-volume cell coupled to a Thermo iCAPQ ICP-MS Sample introduced using an ARIS capillary via an (optional) in house signal-smoothing device. Samples analysed as spots, rasters or 2D/3D maps using a rotating adjustable rectangular mask (6-156µm).
Samples	Holders for 4 x 5cm (or 2 x 7.5 cm) thin sections and 3 x 2.5cm round epoxy mounts and for 9 x 2.5cm round epoxy mounts. Regularly used for analysis of volcanic glass, sulphide minerals, apatite, filter papers, and carbonates.
Additional information	We were the launch customer for the iCAPQ in Ireland and a trial site for the ARIS device.
