When repairing Agilent 7800 ICP-MS atomizer blockage, the following precautions should be noted: 1. Confirm the blockage first: During operation, observe if the internal standard element signal is significantly reduced and the atomizer pressure is increased—these are key indicators of blockage. 2. Proper cleaning steps: Use acid blank and deionized water to flush the atomizer for several minutes (recommended at the start and end of use); use 3%-5% acid solution for cleaning. If the blockage is severe, carefully remove the atomizer to check for damage (avoid damaging components during disassembly). 3. Prevention awareness: To avoid recurrence, filter all samples and solutions to remove large particles, and cover samples, standards, and cleaning solutions to reduce dust contamination.
