Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant, a mechanical engineering student, inquires about the use of the CP 3800 GC and expresses difficulty understanding the documentation.
  • A former Varian field service engineer shares their experience with the CP 3800 in cleanroom environments and provides a link to a product brochure.
  • Another participant requests tutorial resources for the CP 3800, mentioning difficulty finding university-level materials.
  • A user describes their application of the CP 3800 in conjunction with mass spectrometry for drug detection in urine or blood, noting challenges in identifying drugs due to extraction quality.

Areas of Agreement / Disagreement

Participants express varying levels of familiarity and experience with the CP 3800, with no consensus on the availability of tutorial resources or the effectiveness of the machine in specific applications.

Contextual Notes

Some participants mention the complexity of the documentation and the challenges faced in practical applications, indicating a need for clearer instructional materials.

Who May Find This Useful

Mechanical engineering students, laboratory technicians, and researchers interested in gas chromatography and its applications in drug analysis may find this discussion relevant.

Hello people! I am wondering if anyone uses this machine? I am a mechanical engineering student and I have one in my laboratory. I have quite a bit of documentation on the machine, however, a lot of it is like a foreign language to me.

Before I start asking any questions, I wanted to know if anyone uses or has used this machine with the Star Chromatography Workstation?

Thank you :smile:

I worked for Varian for almost 20 years as a field service engineer but on ion implanters. I ran into the 3800 a few times in cleanrooms around the world. Here is a Varian clip on the beast:

Hi litup :smile: Thanks for the clip. The more the better. I am looking for some "tutorial" type stuff. I was hoping to find something at a university website somewhere, but no such luck yet. If anyone knows of something like this, feel free to point me in that direction.

That is one cadillac machine! Here is a "getting started" manual for the model. I don't know if you have a paper version of this manual, but it's pretty darned big for "getting started".

We use the CP-3800 coupled with a mass spec to "scan" for drugs extracted from urine or blood. It's OK, but sometimes the drugs are hard to find. Our supervisor loaded a library of ions to "teach" the computer some of the common drugs we are looking for; but it can be hard to pry them out from the junk if your extraction is bad.

Does that help?
