Hi Everyone,
My lab is looking to purchase a few thermal desorption tube systems and I don't have any prior experience working with these types of systems. I'm looking to see if anyone has any experience with tube desorbers and could provide me with a recommendation on systems they like.
I'm currently looking into tube desorbers from Markes and CDS Analytical.
For thermal desorption you may want to consider a couple of additional vendors.
CDS Analytical - 9350 and their new robotic sampler
Perkin Elmer - Turbomatrix
Markes - has a couple options on the Unity line
Gerstel - TDU as part of their MPS rail system
The above list is in order of relative cost. I am aware Shimadzu makes a system, but it may be a rebranded Dani, it depends if you are in EU or USA.
Try each one with the compound set you work with. Also look at from a workflow and consumables standpoint. How expensive are traps and tubes, can you repack them yourself, are you allowed to repack? Take a look at ease of maintainance, changing traps, o-ring, transfer lines. Gases, some options require liquid nitrogen.
I wouldn’t make a recommendation without more information from you. Contact vendors, get quotes, study flow diagrams, ask more questions here.
