I am using Tenax TA (0.1g per column) as adsorbent for my floral scent analysis. I bought Tenax TA from Sigma, prepare the column by myself and preform the experiment as suggested by Raguso et al (www.nbb.cornell.edu/ragusolab/Floral%20Scent%20primer.doc). I want to ask that how many times I can reused the Tenax columns for different samples? I always wash the column with 2ml hexane at least 5 time and leave them in oven at 80C overnight.
Tenax TA can be applied both as a column packing material and for traps for organic volatile and semi-volatile compounds.Tenax TA is a porous polymer resin based on 2,6-diphenylene-oxide. It is the most widely used adsorbent resins for use with Purge and Trap Thermal influenced compounds. During measurement grams of Tenax and certain volatile organic compounds are trapped on the resin that results in an increase in the GC column temperature. Tenax columns for different samples can be used only for tow to three times. Extra use effect results and authenticity of separated compounds.
I don't know if it's a good source (same kind of polymer ?) but you can find an answer in this document http://www.ingenieria-analitica.com/LlocIA1/PDF/MARKS/PDF/Publicaciones/24%20Using%20UNITY%20to%20recollect.pdf
"reusable 100-200 times"
