1. I am looking for the RS232 command language for a HP Autosampler and HP-5890 GC for a school project. We want to communicate to the HP autosampler but can not find the RS232 command language. Do you know where we can find information on how these Hewlett Packard products RS232 communicating works? We want to talk to it. OR can you send me the HP command set? Any help would be appreciated, Thank you very much,

The RS-232 commands that operate some of the Agilent/HP hardware units are propietary and can only be obtained from Agilent by contacting Agilent directly.

2. I worked in the GC-GC/MS section of my company for ten years using various versions of the Agilent/HP ChemStation software. I transferred to the LC-LC/MS group, which also has some GCs. All the equipment is Agilent. When I transferred, I thought I would have no problem because I have so much experience with the ChemStation. The software in this new job says its ChemStation, but it is totally different. The GC software is even different. What?s going on? (id=130)

There is no such thing as ChemStation software from Agilent. There is the Agilent ChemStation, which is for LC, LC/MS, CE, CE/MS, and GC. This software has the Agilent-internal name of LeoChem. There is also what is now called the MSD ChemStation, which is for use with the GC and GC/MS. This has the Agilent-internal name of Mustang. For a long time, Agilent made reference to ChemStation (LeoChem) and MSD ChemStation. The two software packages are very different in many aspects. The data file formats for LeoChem and ChemStation are the same; therefore, as pointed out in another ChemUserWorld FAQ, you can look at and process your GC and LC/MS data from the Agilent ChemStation (LeoChem) in the MSD ChemStation (Mustang) Data Analysis.

3. Is it possible to control more than one Agilent GC/MS with one MSD ChemStation? (id=11)

Yes. The G1701CA MSD Productivity ChemStation is capable of simultaneous control of? up to two (2) Agilent 5973N Network GC/MSDs or up to four (4) LAN GCs or any combination there of. For more specific and detailed information on multi-instrument control,? please send a message to Ask Dr. ChemStation.

4. Can I acquire and process other chromatographic data with the MSD ChemStation? (id=47)

Yes. The MSD ChemStation software (G1701B rev. B.00.01) or later supports up to 4 detectors. This can be any combination of GC detectors (Agilent GCs: 5890 series II/III and 6890s) and up to 2 MSD max. There are some product limitations. The Agilent 35900D/C/E analog to digital converters where also supported for a period time.

35900D External A/D: G1701AA rev. A.02.00 > A.03.00

35900C/E Internal A/D: G1701AA rev. A.02.00 > G1701BA rev. B.02.00

5. How do I determine the version of my GC/MS MSD ChemStation? (id=85)

There are two ways. The easiest is to click on Help on the Main Menu Bar. Then click on About on the Help Menu. This will cause a dialog box to be displayed that will contain version information. Some versions of the GC/MS ChemStation will have a Revision History item on the Help Menu. This will provide you with a history of verious versions you have installed. The file INSTALLD.TXT in the \Msexe folder, which is in either the \MSDChem or \HPChem folder, depending on your version contains the revision history and can be viewed using Note Pad.

6. We have two 5972 Mass Selective detectors sitting side-by-side in our lab. One has a 5890 GC and the other has a 6890 GC. When we analyze cocaine the 5972 with the 5890 GC produces a spectrum with a base peak of m/z 82 and the instrument with the 6890 produces a spectrum with the base peak at m/z 182. Why is this? (id=90)

The software on your 5890/5972 is probably G1034C and that on your 6890/5972 is G1701AA. When G1701AA was introduced, the atune.u in the \msdchem\1\5972 was changed from using adjustments to produce spectra of perfluorotributylamine (FC-43) that have a base peak of m/z 69 to using adjustments that produced spectra with m/z 219 as the base peak. This change came about as a result of replacing atune.u with the file that was used to tune the instrument for high sensitivity. The old atune.u file has been renamed stune.u (standard spectrum tune). Agilent recommends the use of the stune.u file when tuning the instrument where spectra will be compared against mass spectral data bases.

7. I need the data file format for the HP/Agilent ChemStation. No one seems to be able to tell me where to find it. (id=112)

The data file format for the HP/Agilent has not changed since the days of the Pascal ChemStation used with the 5971 MSD, 5970/5995 MSP and the 5988. This data system was introduced in 1988. The manual, HP 59970 MS ChemStation Handbook (Publication No. 59970-90034 June 1988), contains the details of the data file formats and the integration file formats in Appendix D, File Formats. The data file format covers 16 pages and the integration file results format covers another 19 pages. A copy of this manual may be difficult to fine.
