(GCMS) Daily Startup and Shutdown - GCMS-QP2020, GCMS-TQ series

When the instrument is used daily, the vacuum system should be left running after each use rather than shutting down and restarting it so that the proper analysis conditions can be met more quickly. This section describes how to set the shutdown parameters when the instrument is standing by for analysis and how to execute a shutdown.

 

1. Daily Shutdown

  1) Select [Shutdown] from the [Tools] menu to open the [Ecology Settings] dialog box.

   

  2) In the [Shutdown Method File] text box, enter the name of the method file to download to the instrument when performing a shutdown. To change the method settings, click the [Edit] button and make the new settings in the [GCMS Analysis Editor] program that opens.

  3) Click [Line 1] button in the [Parameters] to open the [Line 1] dialog box.

   

  4) Select which parameters of the shutdown method file are to be downloaded to the instrument, and click the [OK] button. Only parameters whose checkboxes are selected are downloaded to the instrument at shutdown.
  5) Enter the desired settings for the equipment in use on the [Line 2] dialog box and [Additional Heater / Flow] dialog box.

  6) Click [Line 1] button in the [Instrument Control] to open the [Line 1] dialog box.

   

  7) Select the parameters to turn off at shutdown, and click the [OK] button. Only parameters whose checkboxes are selected are turned off at shutdown.
  8) Likewise, make the required settings in the [Line 2] dialog box.
  9) Click OK in the [Ecology Settings] dialog box.

  10) Click the Ecology Mode icon on [Instrument Monitor] in the [GCMS Real Time Analysis] program. A message prompting whether or not to enter the Ecology mode is displayed.

   

  11) Click [Yes]. The [Ecology Settings] dialog box settings are downloaded to the instrument, and the instrument enters the Ecology mode. While the Ecology mode is executing, the [Ecology Mode] dialog box opens. Other operations can be performed in the [GCMS Real Time Analysis] program only when the Ecology mode is canceled.

   

    NOTE: If the front door of the vacuum housing will be opened after the vacuum system is shut down, loosen the knob on the front door with one turn to the left.
    • The instrument will not automatically switch to the power save mode while the instrument is running. The instrument will switch to the power save mode after the current process is finished and a specified amount of time elapses.
    • The power save mode can be activated manually, depending on power option settings.
    However, do not manually switch to the power save mode while the instrument is running. Doing so will cause an error communicating with the instrument.
    • This feature is not compatible with pretreatment units other than HS-20 or AOC-20.
    For information about power save mode settings, refer to the instruction manual or help menu for Windows.

 

2. Daily Startup
  Follow the procedure below when the vacuum system is already running, as when the daily shutdown procedure has been performed.
  1) Click Cancel in the [Ecology Mode] dialog box.
    The instrument automatically returns to the state before the Ecology mode was entered.

    NOTE: When the PC is in the Power Save mode, first cancel the Power Save mode and then cancel the Ecology mode.
    For information about power save mode settings, refer to the instruction manual or help menu for Windows.

    NOTE: Do not connect or disconnect devices connected via USB (such as USB memory or printers) or switch the power OFF/ON while the [GCMS Real Time Analysis] program is running. Doing so could interfere with communications.
