The final day commenced with an in-depth discussion on the progress of interlaboratory comparisons, led by the coordinating laboratories. Proposals for new interlaboratory comparisons were also presented, addressing issues related to air pollution.
At the conclusion of the meeting, Dr. Hai Wu, Chair of the Gas Analysis Working Group, presented the group’s strategy for 2025–2030. The strategy focuses on developing high-accuracy, SI-traceable gas reference materials for carbon dioxide, methane, nitrous oxide, and carbon monoxide, with the aim of reducing uncertainties to meet the compatibility goals of the World Meteorological Organization’s Global Atmosphere Watch (WMO-GAW).
Following the discussions, participants visited the Gas Laboratory at NMIM, guided by Dr. Mohamad Fauzi and Mr. Mohammad Khairul.
The day concluded with an industry visit to Air Products factory where participants gained valuable insights into their gas filling operations and safety. Our sincere thanks to Air Products for their warm hospitality.
As we bid farewell to this enriching event, we leave with valuable knowledge, new connections, and memorable experiences from these three impactful days. Heartfelt appreciation goes to all speakers, NMIs, participants, and organizers for making this event a success. Until we meet again!
