GC 436 Bruker startup

Hiep, Did you do a complete reboot of both the GC and computer? Shut both down completely, reboot the GC and computer and allow them to both boot up completely before starting the software. Dan

Hi Dan,

Thanks for your reply

I have rebooted both PC and GC as well. PC rebooted normally while GC rebooted to the point it says "starting up, please wait" and it does not want to continue booting. Any other thought, Dan?

Cheers,

Hiep

Hiep,

I dont have a lot of experience with this particular GC but it sounds likes an electronic issue of some type.  As you were having Oven heating issues, I would verify that all of the fuses are good and that the heating element for the oven is not broken (use an ohm-meter to check the resistance of the element).

Hi Dan,

one of Bruker engineers said that log errors stored in the past cause the booting problem to the GC.

I read something about 456GC Bruker that when battery in the GC mainboard is placed then the GC will boot again normally. what do you think about that? do you reckon if i should try this as the final solution?

Regards,

Hiep

Hiep, A bad battery could certainly be an issue. I would go ahead and replace it. You may have to reenter configuration settings. Dan

Hi Dan,

The Bruker engineer has solved the starting issues. They have fixed on the software and software administrator through our IP.

Now I currently have a problem with my Shimadzu GC-2014. We run gas analysis on TCD and FID for H2,O2,N2, CH3, CO, CO2, C2H4, C2H6, C2H2. For some reasons I the system couldn't reconize H2(hydrogen) and has low concentration of all other hydrocarbons. I am going to do something on the column or dectector. Do you have any idea what causes the problem?

If retention times are consistent with what they have been and you simply have reduced response, then less sample is getting to the detector.  Verify that detector gas flows have not changed (can cause some variations in response) and then check the inlet for leaks.  I assume you are using a gas sampling valve, so check for leaks there as well.  If using a GSV, make sure the sample pressure has not dropped from what it was.

 

One other possibility is if you are splitting the injection, verify that has not changed as well.

This is occurring to me currently the message log says it unable to save raw data & that the packet is out of sequence. 

Did you document what the tech did specifically?   When you mention fixing it through admin, do you mean the compass config?
