The TubeConditioner TC 2 is a device for the simultaneous conditioning of up to 10 thermal desorption tubes. Condition is performed in accordance with a time and temperature program. Not only sorbent tubes and empty tubes but also Twister can be conditioned. As a stand-alone device, the TC 2 does not make use of any additional GC resources.
Functional principle of the TC 2
Tubes inside the TC 2 are heated up and purged with inert gas. This releases and purges the impurities from the tube. The duration and the temperature at which condition is performed can be set individually, along with the heating rates and temperature ramps. The programs can be saved in 10 methods and reused at any time. During conditioning, the tubes are sealed airtight. After one or more runs, the tubes have been conditioned.
Benefits
Contaminated tubes and Twisters can be conditioned at any time. This ensures that the analytical device is neither blocked nor contaminated.
The TSS option enables the automated production of solvent-free standards in sorbent tubes using the MultiPurposeSampler MPS. Automating this process using the MPS makes production reproducible and the dosing of the standards precise. The system is controlled using the MAESTRO software. Within the software itself, all sample preparation steps can be prepped ahead to save time.
Functional principle of the TSS option
The TSS contains 5 sorbent tubes. The MPS injects the standards mixed with solvent into the sorbent tubes. Inert gas flows through the tubes in a controlled way and removes the solvent. The analytes remain on the adsorbent and can then be desorbed solvent-free.
Benefits
The TSS option enables the reproducible production of solvent-free standards in sorbent tubes. Using the MPS enables the dosing of the standards to be precise. Calibration series are easy to produce. For increased productivity, you can use multiple TSS in combination. Thanks to the MAESTRO software, controlling the system as a whole is simple and intuitive.
The TE is a Thermal Extraction sample preparation system for bulk samples to be analyzed using a Thermal Desorption (TDU, TD 3.5+ or TDS) System. It has been widely used to determine the emission potential of materials used indoors in vehicles and in commercial or residential buildings.
A solid or gel sample is placed into the TE tube and is heated to the desired temperature. Volatile and semi-volatile organic compounds (VOC and SVOC) are extracted from the sample and transferred to a TD sorbent tube with a carrier gas flow. The compounds are then determined using the Thermal Desorber (TDU, TD 3.5+ or TDS) in combination with a GC-MS(/MS) System
For quality control of a total aroma extraction in combination with sensory-directed analysis (SDA), the total aroma extracted, for example, by DHS onto a sorbent packed tube, can be desorbed in the TE and assessed for completeness by the olfactory specialist directly at the exit.
