Key instrument capabilities

Standard specifications of ANALYTE G2 laser system can be found on Teledyne CETAC or Teledyne Photon websites. Our system, however, has significant in-house customisations as we are collaborating with Teledyne Photon Machines in research and development of next generation laser facilities.

Unique specifications of our system include:

-        Large volume (150 mmx150mm) Helex ablation cell with in-house deigned sample holder for coral and speleothem samples (Video here).

-        Improved inner cup for ultra-fast washouts (0.25 sec to 1% levels) based on  our Computational fluid dynamics modelling 

-        Rotating aperture with large beam size of 250x250 um which allows tracing of coral/speleothem growth bands and map complex geological features with less than 5 um spatial resolution. 

-        Distortion and leak-free particle transmission line to ICPs, which include customised CleanShot and various in-house build signal smoothing units (6 and 12 holes squids for smoothing 4hz and 2hz signals) and centrifuge particle filter with option of ‘wet plasma’ laser ablation.

International team head to Papua New Guinea to measure volcanic carbon degassing

Sep 01, 2016

An international team of scientists is traveling to the islands of Papua New Guinea this September to study degassing from active volcanoes in remote jungles there. Some of these volcanoes are among the most active on Earth, ejecting a significant proportion of global volcanic gases into the atmosphere.

Mistaken Point - Canada's 10th geological World Heritage Site
