The new water quality laboratory of M-TROPICS has been set up at DALaM in Vientiane. DALaM contributed with the premises and oven. Christelle LAGANE (IRD GET) installed both Milli-Q water supplier and ionic chromatography, and trained Khampaseuth XAYYATHIP (IRD DALaM) and Inpeng SAVENG (DALaM), who will be starting her PhD at GET on November 2023 under the joint supervision of Olivier RIBOLZI (IRD GET) and Laurie BOITHIAS (UPS GET). In the meantime, Chanthanousone THAMMAHACKSA (IRD DALaM) trained Khampaseuth and Inpeng to the measurement of E. coli concentration, total suspended sediment concentration, and alkalinity. The new lab will run the analyses for the 9 sampling stations monitored by M-TROPICS within the Mekong River basin.
