Hooking up 5890 to MS and availability of parts for older MS

[MSCHemist]

Hi all. I could use some advice:

I have been asked to look into getting a refurbished MSD for our old 5890 as cheaply as possible. The MS isn't needed for anything too demanding. We wil just be injecting flavor raw materials solutions and verifying their identity and puruity. No need for high sensitivity.

The 5890 I have was originally hooked up to a MSD I believe a 5973 or 72 though oddly the black plastic shell in the GC side door is unbroken. I was looking for a 5973 but I am seeing a lot of old 5971A's dirt cheap. However I am concerned about parts availabilty for them what if I need source parts, detector horn, pump etc?

Here is my current configuration, It has an FID.
5890A.03.01 main board
EPC-injector
7673 autosampler G1512A controller hooked up with a GPIB and remote cable
HP82341 card
Chemstation G1701BA B.01.00 version on Windows NT

How would it cable together? Also is there a source for old Chemstation CD's? I managed to dig up all the chemstation license information and operating system CD's but could not find the chem station CD.

Reg. the MSD detector, the software you have does not support 5971A detectors as far as I know. You need an older MSD chemstation for it to work, and be forced to work with windows 95. I think with your BA version that you might be able to work with windows XP as well. You'll probably have to stick with the 5972 and 5973. Besides the PC software, I am not sure if there are also firmware issues and lack of support of the 5971 by your instrument.

We just removed a perfectly-working 5972A from a GC here, so that the GC could be hooked up to a new internal network. It's sitting on a cart right now. Supervisor decided that since we had 3 newer GCMS systems that we didn't need that one to be kept as a GCMS.

Are you interested, would be real cheap, that's for sure, or for trade. I don't know if he'd just agree to donate. I've used that 5792A since 1996, and we had it hooked up to a computer with Windows NT. That computer could be part of the deal as well.

That would be perfect. You can reach me at sschoenfeld[at]innovaflavors.com

The only other issue I guess I need to be aware of is there are different interface lengths and it needs 214mm to reach through the side plumbing compartment and into the oven of the 5890.

The interface options are offered in three versions. The 68 mm interface is designed for the HP 5710 or 5790 Series GCs. The 94 mm interface is for the HP 5880 GC, and the 214 mm interface is for the HP 5890 GC.

MSCHemist - I'll check with my supervisor.

Our interface is the longer version about 220 mm total length (I just measured it); it was used with a 6890 GC. We didn't have any sensitivity issues with it, just supervisor wanted to go network with that 6890 GC as a networked GC-FID, so he could remove a 5890 system.

Well we'd definately be interested in buying it from you as our 5890 used to be hooked up to a 5972 about 8 years ago. It'd be easy to set up. I found the cabling diagrams looks like the only other part I'd need is an additional 8120-4654 HP-IB cable.

220mm interface would be fine anything shorter than 214 and it wouldn't make it into the oven.

MSChemist - I'll be contacting you by E-mail within a few days (E-mail is down today). Boss says your company should make an offer for the MSD and software. He says the vacuum pump is worth like $1K on its own, as we can use as a spare someday, so itemize if you need the vacuum pump as well.

The computer might need to have proprietary stuff wiped off of that as well, if you want that too.

My guess is that we also have HPIB cable, and in any length you might need.

[MSCHemist]

We don't need the computer. Just MSD, interface, vacuum guage controller, pump, cable, and what controls the interface temperature? Also a chemstation B disc if you have one. We have the license information but I couldn't find the CD itself.

However it already has chemstation MSD installed and it looks like it is set up for a 5972 as that was what we had 8 years ago.

[KM-USA]

There is an accessory vacuum controller box, but that malfunctioned a few years ago, didn't bother us; so don't know if the sender part or the gauge was bad, or something else.

The 5972A MSD is heated by transfer of heat from the transfer line. That transfer line is heated by the GC as an AUX zone.

Yep that part is a bit puzzeling there are two style interface cabling because there are two different types of heater/sensor assemblies.

I assume you have part #05972-60106 which is the sensor that has the newer style union that goes with the 6890GC.

According to
http://www.chem.agilent.com/Library/Sup ... a20567.pdf
I would need to buy part 05989-60074 which is the GC to interface union cable for the 5890 that has the newer style at the union with the MS interface cable. Then the two prongs/wires at the GC end of the cable fit into the black rectangular connector bundle that slides into the main board.

[MSCHemist]

OK scratch that the 6890 heater/sensor assembly is totally incompatabile with the 5890 the cable earlier is for interface heater/sensor 05971-60105 for the 5890. So I'd need to replace the heater/sensor assembly and buy the cable unless you have a 5972 to 5890 sensor assembly.

Our interface is the 05972-60106, it has that part number on it. It's white, squarish, and has four connections. I can E-mail a photo of it if that helps.

If still interested in the unit, let me know and I'll shoot out an E-mail.

Sure even if I have to replace the heater/sensor that is only ~$400. Does it have the Edwards rough pump?

[KM-USA]

Yes, Edwards. I'll send an E-mail.

We had a meeting and decided not to go with a 5972 or older. They say that our old 5972 was a huge pain to get at and clean the source and since we will be injecting large amounts of very dirty samples it is a deal breaker. Also there were concerns about IT and old computers. I don't think it is a big issue but I won't be running it. We decided to get a 6890-5973
