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 for9 x 2.5cm round epoxy mounts.
Regularly used for analysis of volcanic glass, sulphide minerals, apatite, filter papers, carbonates.

Additional information:

We were the launch customer for the iCAPQ in Ireland and a trial site for the ARIS device.
