No. The manual states that a UPS should not be used with the GC because it can create unsafe conditions.
The instrument uses 20 A, 250 Vac IEC 127 type f fuses for the AC board and 8 A, 250 Vac IEC type fuses for the logic board, and they must be replaced only by trained Agilent service personnel.
Hydrogen is highly flammable; ensure all connections are tight, check for leaks before operation, keep the gas valve closed when the instrument is not in use, and never operate the GC with open hydrogen lines.
Turn off the power and wipe the instrument with a lint‑free damp cloth; do not use cotton‑based materials.
