I'm in the process of learning the use of GCMS in a fragrance company to analyse raw materials and compositions and would like to connect with others with this background. Thanks!

Hi,
I'm working in Gc-analysis.
I'm analysing fragrances and doing QC on raw materials.
What is your background in this domain ?
Are you going to start without any experience and tutor ?
Let me know if I can help.

Flavors and fragrances - my favorite subject of anaysis. I've worked with these over the years. If I can be of help, let me know.

We ended up making our own fragrance component GCMS search library, using injections of raw materials, and used the names perfumers use. We injected like 20 each night, entered them in, injected 20 more the next, etc. I believe we have something over 1000 spectra, and retention indexes. It took several months. Retention index is needed because several terpenes have similar spectra, and stuff like n-amyl- and iso-amyl-

For a flavor MS library, tale a look at the essential oils library published by Allured. While it may cost some money, you will have many more spectra and retention indicies in hand in the time it takes for the CD to ship to you. Now, if you want these on a different stationary phase than was used for the Allured library, you have some hours at the GC ahead of you.

@Don_Hilton, thanks for the pointer to "allured.com" books, they have a CD with mass spectra for fragrance material, the price is kind of okay (750 USD).
I'm looking for FFNSC (Mondello) in a version previous to 1.3 (currently on the market and priced around 3.000 USD - not affordable). So something like 1.2 or 1.1 - significantly cheaper - I would like to buy. Any offers are welcome! stephan DOT lindner @ web DOT de
Thank you!
I'm currently working with a NIST05 and I'm recording additional spectra from my own fragrance raw material library. However, this will take ages and I only have about 400 raw materials.

And another colleague...
I'm doing natural products analysis (both GC-MS and LC-MS-MS), including essential oils.

Add another colleague also. I'm also new to flavors and fragrances and working on building my own library too.
