LA IRMS sequential sampling of pine needles for 𝛿¹³C analysis

We’re pleased to publish a new application note using the Laser Ablation IRMS techniques pioneered by a collaboration between Sercon, Terra Analitic and Teledyne Photon Machines.

Great Basin bristlecone pine (Pinus longaeva) exhibit individual growth responses to variability in both temperature and soil moisture within growing seasons. Additional physiological data is needed to better understand the key drivers of xylogenesis and will improve our understanding of the physiological capacity of this species to perform in a warmer, drier future.

The traditional approach uses entire leaves that are ground and homogenized, integrating the average annual isotope signature and providing insights into annual intrinsic water use efficiency and overall plant water balance. But do different regions of leaves vary in their carbon isotope signature as they develop within a growing season? We developed a method to use laser ablation (LA) IRMS for in situ, high-resolution, sequential 𝛿¹³C analysis of bristlecone pine needles.
