M4 Mercury Monitoring System
Precise, accurate, and reliable
Page last modified
April 11 2024
ISCT M4 volatile metals measurements systems are specifically designed to measure total gaseous mercury, arsenic and selenium in process gas streams such as natural gas, sour gas, fuel gas, LNG, LPG, butane, ethylene, propylene, hydrogen, carbon dioxide and Syngas. M4 systems and sample teams can be deployed from Texas, South Africa and New Zealand to support measurements projects for upstream, midstream and downstream assets globally. Services include Mercury Rumoval Unit performance evaluations, mercury mapping, distribution studies and total asset management.
Pros & Limitations
1
Redesigned with new inert materials
1
Multiple sample trains to run gold or solid sorbent traps plus functional speciation traps
1
Strict QA/QC criteria
1
Different configurations to connect to a detector, mobile Cold Vapour Atomic Fluorescence Spectroscopy (CVAFS) or onsite analysis using combustion method
1
Minimized effects from wet gas environments
1
Provide long term integrated average concentrations
1
Reduced deployment costs – light weight, mobile and can travel with sample team
1
Designed for extreme environments (-10˚F – 125˚F)
1
Measurements for mercury, arsenic, selenium
0
Providing accurate and reliable data could mean asset managers may have to revisit former risk models where data was collected 5-10 years ago with less precision
