Portable sampling units and automated air sampling devices of AMA Instruments are used to take an exactly defined air volume referenced to standard operating conditions. All devices allow for volume or time-based programming in the field and can be either line or battery powered.

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.

AMA Thermal Desorption Systems use special sample sleeves made of stainless steel, which are also used as the heating element. The adsorbent or sample tubes will be inserted into these sample sleeves and locked absolutely gastight with a septum in each sealing cap. This protects the sample tubes during transportation. Any sample loss or contamination of the sample will be avoided thus maintaining the integrity of both cleaned and sampled adsorbent tubes.

Depending on polarity, boiling range or other properties of the compounds to be determined various focussing capillaries are available. This allows our customers to configure the AMA Thermal Desorbers for analysis of low boiling organic components from C₂ as well as analysis of sticky and high boiling or easily decomposable organic compounds in order to cover a wide range of different applications.
