I work in a lab that analyses aroma/volatile compounds in food and dairy products by GCMS. We've recently started switching our instruments over to mid polar columns from non polar. We rely a great deal on retention indices to help with the identification of compounds. Using non-polar columns we've built up our own database of indices over the years, and use online databases such as NIST and publications for referencing and comparison. While there is a relatively large amount of info for retention indices on non-polar, semi standard non-polar and polar columns; there is a lot less info available for mid-polar columns. So basically I'm looking to reach out to anyone who uses these columns and relies on retention indices also. Any info on good publications/databases or even your own work would be greatly appreciated. I'd also be happy to share our own database of indices that we've compiled using non-polar columns.
Thanks in advance
