Adsorbents- and Sample Tubes

For indoor and outdoor air monitoring applications, e.g. in conjunction with occupational health and safety monitoring, sample tubes with various adsorbents for all kind of applications and differing boiling ranges are available. These tubes meet the requirements of thermal desorption standard methods according to VDI, DIN, EN, ISO and US-EPA directives.

Sample Sleeves and Septa

The sample sleeves are made of stainless steel and will be used to insert the adsorbent or sample tubes. Afterwards the tubes are locked absolutely gastight with a septum in each sealing cup. Any sample loss or contamination will be avoided thus maintaining the integrity of both, cleaned and sampled adsorbent tubes.

Plunging tube adapter

The plunging tube adapter is used to hold the sample sleeve while sampling. After inserting the sample tube sleeve into the adapter, the septa in each sealing cap will be punctured thus making them permeable to the gaseous sample. When removing the needles after sampling, the septa will seal the inserted adsorbent tube absolutely gastight again.
