The document describes the precautions for using hydrogen gas in Agilent 7500c ICP-MS, including the hazards of hydrogen gas, the dangers of hydrogen gas during ICP-MS operation and the precautions for shutting down ICP-MS.
The document serves as a safety guide for the Agilent 7500c Inductively Coupled Plasma Mass Spectrometer (ICP-MS), which utilizes hydrogen gas. It details the specific characteristics of hydrogen that pose risks, such as its wide flammability range, high burning velocity, and low ignition energy.
Key sections address dangers during operation, including combustion from leaks or rapid expansion, and accumulation within the vacuum system. The guide provides critical instructions for safe shutdown procedures to prevent accidental accumulation due to power failures or internal faults. It also lists necessary precautions, such as checking for gas line leaks, eliminating ignition sources, and ensuring the exhaust duct is always operating.
Hydrogen is combustible at concentrations from 4% to 75%.
To prevent hydrogen from accumulating in the ICP-MS or the exhaust duct, which could lead to combustion.
