#Agilent 3000 micro gc sold to inficon software#
I can make it work for me, and to be perfectly honest, it is FAR superior to the Star software we are using on my Varian/Agilent MicroGC. The Agilent/Inficon MicroGC uses Cerity, which I hear quite a bit of whinging about. May be better suited for the Software subforum. According to Inficon, however, I should be able to replace the column itself without replacing the whole module, which should be substantially cheaper.Īnyone have any experience with this? How tough is it? I'm pretty mechanically oriented and have little difficulty working with 1/16" tubing and the like (I can tell the difference between Bucci and Swagelok 1/16" ferrels.)įinal question.
#Agilent 3000 micro gc sold to inficon upgrade#
At that price I am more likely to upgrade this GC to the Varian/Agilent MicroGC I have on my other reactor. The column modules themselves are prohibitively expensive, roughly 5-7k each. Second question has to do with replacing GC columns on a 3000 MicroGC. What other possible causes can you think of for the RT shifts? Could any of these faults have hidden RT shifts? Only thing I can guess is that increasing the column temp/pressure rapidly increased the column degredation.Īlso about 7 months ago we sent the equipment in for repairs to the OBC, while there the inlet ass'y was replaced, and EPC valve and pressure sensor was replaced for the molsieve/plotu column, and the detector and flow ass'y die was replaced for the Al column. As far as I can tell the shifts were much slower in the years before. I've seen almost a 100% shift in the last year. What's surprising to me is that the RT shifts have accelerated dramitically since I took over operation of the GC. My guess is that RT shifts are due to column degradation. They were within the "safe" bounds given by Agilent, but right at the edge. (Surprisingly, previous owner no longer works here.)Ĥ) To try and push RT times down I increased column temp/pressure.

When I have an acceptable level of downtime I will be installing a couple of driers.ģ) Previous owner installed 'home-made' in line filters which was an emptied check valve with a 3 um T-Type filter element held in place with a spring. It exclusively uses UHP carrier gas, but I don't buy that that is enough. I have 2 columns, a molsieve backflush with a PLOTU precolumn and an Al columnĢ) Previous owner never installed driers on carrier gas (sample gas is dry).

The limiting factor is hexene which comes in ~4 minutes. Right now its taking almost 4.5 minutes between each run. I've dealt with it by updating the method as I go, but this GC does online monitoring and the more I push back my RTs the worse my sampling resolution gets. I've been having problems for the last year or so of RT drift on one of my GCs, an Agilent/Inficon 3000 MicroGC. I've gotten stuck maintaining a couple of GCs on some test reactors I work on, and am learning but, like I said, no expert.Īnyways.
