Answer

  • Do not open or close the main valve of the supply gas during APC operation.
  • Restart the GC with the gas supplied.
  • Check that the hydrogen gas supply pressure is within the range below.
  • Check that the gas supply pressure is stable.
If the error appears repeatedly even after checking the above, the control system of the APC may have failed. Turn off the main power of the instrument, stop gas supply, and contact your Shimadzu sales/service representative.
