Each tube is etched with a unique serial number for ease of traceability and adsorbent identification. Stainless steel tubes may also be fitted with clips that accept adhesive labels for identification. Packed tubes are shipped with long-term brass storage caps and all tubes are thermally conditioned and tested for background and backpressure.
Tubes are offered with a variety of sorbent packing materials for many GC applications including indoor and outdoor air monitoring, analysis of flavors and fragrances and the analysis of outgassing from packaging, polymers, pharmaceuticals and semiconductor material.

SVI Soil Vapor Intrusion?TubesSoil vapor intrusion occurs when toxic compounds that are present in the air space in soil of a contaminated location have ways of entering a building, potentially creating a health risk.
The Carbopack? B is conditioned at 350 °C. PerkinElmer recommends a maximum temperature of 400 °C for this sample tube with a desorption temperature of 330 °C. The tubes approximate analyte volatility range is n-C5 to n-C12 and the typical analytes for the Carbopack? B are a wide range of VOCs.
Required for installation of the following options on an entry-level thermal desorber - Internal Standard Addition, On-line Sampling, or Liquid Nitrogen Cooling. Also provides output of BCD
information regarding tube position numbers and provides relay output for timed control of external devices.
