SAPHTIES & MINKE pHT Interlaboratory Comparison
SAPHTIES & MINKE pHT ILC took place from the 30th of October to the 24th of November 2023.
The ILC was opened to both users of the spectrophotometric pHT method with benchtop spectrophotometers and to users of other types of pH or pHT instruments.
Objective: to demonstrate the performance of the improved ISO 18191:2015 spectrophotometric method including the pHT interval between 7.4 and 8.2, the temperature interval from 0 °C to 30 °C and a practical salinity interval between 5 and 40.
Preliminary results will be presented at the Stakeholder workshop the 29th of April 2024.
