Latest Patents
Among his latest patents is a groundbreaking **Method for analyzing stable isotopes of particulate organic carbon (POC) and nitrogen in seawater using elemental analysis-isotope ratio mass spectrometry (EA-IRMS)**. This method involves several crucial steps: First, a glass fiber filter membrane is employed to filter a collected water sample, followed by the filtration of 100 ml of distilled water. The resulting membrane sample undergoes acidification, after which it is subjected to EA-IRMS analysis on a machine. Specific parameters include an oxygen addition time set to 80 seconds and a combustion tube temperature set to 700°C for the elemental analyzer. Additionally, a trap current is maintained between 300 µA and 400 µA for the isotope ratio mass spectrometer. This innovative approach not only reduces detection costs but also improves data accuracy and work efficiency for researchers.
