TDS – Lab Alliance

Pyrolysis Module (PM 1)

Using the temperature programming capability of the PM 1 and the TDS, samples can be thermally desorbed prior to pyrolysis, in order to remove interfering volatiles and get a cleaner pyrolysis GC/MS analysis. This means that more and better information can be obtained from a single sample. First a Thermal Desorption GC/MS run is performed in order to get information on residual monomers and/or solvents in the sample. Secondly, the pyrolysis GC/MS analysis is performed with best possible results.

The TDS can be converted from pyrolysis to thermal desorption analysis in just a few minutes.

The GERSTEL Pyrolysis Module (PM 1) is easily and conveniently controlled from the MAESTRO Software – stand alone or through the Agilent Technologies ChemStation software.

Tube Standard Preparation System (TSPS)

The GERSTEL TSPS is designed for the preparation of solvent-free thermal desorption standards for use in air and industrial hygiene analysis. TSPS provides an excellent alternative to commonly used 'one-at-a-time' classic methods. The TSPS is simple in design, speeds up routine laboratory procedures and can be easily used by staff with any level of technical training. The TSPS can be equipped with up to six GERSTEL thermal desorption tubes that are easily attached using a specially designed connection system.

GERSTEL Tube Conditioner (TC 2)

During conditioning in the TC 2, TD tubes are either held at a user-specified fixed temperature or undergo a specified temperature program cycle while being purged with inert gas to efficiently remove contaminants. Up to 5 Twisters will fit into an empty TDS tube, allowing up to 50 Twisters to be conditioned in one batch. Each tube has independent gas flow regulation enabling the conditioning of one to ten tubes without the need to adjust flows.

The TC 2 helpds to ensure that conditioned TD tubes and Twisters are always available providing best possible quality of analysis.

Thermal Extractor (TE)

The TE is a preparation system for bulk samples to be analyzed using the Thermal Desorption System TDS. A solid or gel sample is placed into the TE tube and is heated to the desired temperature. Compounds of interest are transferred into the TDS desorbent tube with a carrier gas flow. The compounds are the determined using the Thermal Desorption System (TDS).

TDS-A Autosampler for TDS

allianceadmin — Fri, 08 May 2020 07:30:28 +0000

Adding the TDS A Autosampler enables your Thermal Desorption System (TDS) to perform completely automated processing of up to 20 samples using one or more analysis methods.

The TDS-A performs:

Desorption of glass or stainless steel tubes
Automated desorption of 178 mm and 3.5" thermal desorption tubes
Leak tight storage in exchangeable magazines
Efficient MAESTRO Software control - stand-alone or fully integrated with the Agilent Technologies ChemStation

Thermal Desorption System (TDS)

allianceadmin — Fri, 08 May 2020 07:27:09 +0000

The TDS is mounted on top of a Cooled Injection System (CIS) that is used as cryotrap, focusing and concentrating the components to be determined, and then transferring them to the capillary column in split- or splitless mode without analyte discrimination or loss of analytes. With the addition of the TDS-A Autosampler, the TDS becomes a fully automated thermal desorption system capable of unattended analysis of up to 20 samples.

The TDS G On-Line version enables whole-air sampling as well as direct sampling of gas streams for continous on-line monitoring.
