The plateau includes 5 modules :

– Isotopy of aerosols & soluble chemical species module (NH₄⁺, NO₃^-, SO₄^2-)

– A gas module (N₂O, CO, CO₂ et CH₄) including 2 methods : continuous measures on CFA (CH₄, CO) and discret measurements (CH₄, CO₂)

–  A chemistry module, grouping together a vast instrumental park operating in parallel and continuously from a melting pot of ice bars. This module thus allows multitracer analysis in continuous flow (CFA = Continuous Flow Analysis) and high resolution of a single ice core sample. Around the CFA system are deployed the instruments allowing the following measurements : liquid conductivity, particle counting, colorimetric concentration measurements of NO₃^-, NH₄⁺, Ca²⁺ et H₂O₂, measures of black carbon, of water isotopes, quantification of metals (ICPMS iCAP TQ), and an auto-sampler associated to the CFA for a discrete analysis on an offline ionic chromatography.

– An air isotopy module  : discrete measures of oxygen (δ¹⁸O, δ¹⁷O), nitrogen (δ¹⁵N), argon (36/38/40), krypton (82/84/86) and xenon (129-132) isotopes, as well as the ratio O₂/N₂. An extraction line of kryton aims to analyse < sup>81Kr (collab. ATTA-Hefei)

– A water isotopy module : measures on CFA of δ¹⁸O, δD ; discrete measures of δ¹⁸O, δ¹⁷O and δD.

The analytical plateau PANDA is located :

–  In the « Glaciologie » building of IGE (Grenoble), close to the clean room and the cold rooms of the IGE.

–  In the GLACCIOS team of the LSCE (Paris Saclay) for the air and water isotopy modules.
