An introduction to radiello: a passive, diffusive air sampling badge for VOCs

Today, Restek launched the radiello passive, diffusive air sampling badge for VOCs. Oh… so you do not know what that is. Well then, be sure to check out the following video, which will give you an introduction to radiello:

Stay tuned for future blogs featuring how to properly utilize the radiello.

    Nice video Jason. Very informative. I see in some of the literature that there are sorbent beds amenable to thermal desorption analysis after the air sampling with the Radiello. Do you need special TD tubes to make this work? My system is a Markes TD-100xr that takes standard 1/4″ TD tubes. The i.d. of the glass tubes I use are on the order of 4 mm. The o.d. is about 6.4 mm. It’s not clear to me how the sorbent traps that are 4.8 mm in diameter will work with these empty tubes – or on their own with my Markes system using the end caps for the sample tubes required by the instrument. Can you give me an idea as to what is required to make the TD analysis work?

  2. Matthew,

    Thank you for your inquiry. The radiello 145 is a carbon based sorbent designed for thermal desorption (TD). The rad145 sorbent will snugly fit inside a standard (i.e., 3.5 x 0.25″) empty stainless steel TD tube. Not an empty glass TD tube. I know all of this will work for Markes TD tubes, as that is what we use and sell. Restek cat.# 24054 would be the TD tube to accompany the rad145.
