  • Hello Satya,

    Before responding to your questions we need more information about the installation and what you are doing:

    - Why do you think that the headspace parameters have to be entered manually (into the instrument)?

    - Are you aware the Headspace Control Option (HCO) v2.0 controls the G1888? Is HCO 2.0 not installed?

    - Are there parameters that you need to enter that can't be entered with HCO 2.0?  If so, what are the parameters?

    - Lastly, is it possible that you are attempting to change the Instrument Method when using HCO 2.0?



  • Hi Dot,

    All head space parameters we are giving manually only(Like Vial equilibration,Loop fill time etc....). where we don't have HCO v2.0.

    We have not installed HCO.

    After i saw your reply i had  talk with  local Waters representative.We need write a mail to them .

    Because of weekend we are on hold .

    And one more thing what about Linear velocity option in GC instrument method editor.

    Any updates regarding.

    Please can you share the exel if avalable other the agilent flow calculator link wht tyou have send previously.



  • Hello Satya,

    You can locate the previous discussion on Linear Velocity and the excel calculation by searching the word calculator.

    The discussion topic was "Re: There is no option to give Carrier gas interms of lenear velocity in all my Agilent GC instruments."

    If you cannot locate it let me know.



  • Hi Dot thank you.

    I tried to down load it, but i could'nt....

    And the excel is complex as you said in that post

    Please share other than the links from Agilent if any.
