TD-30 Thermal Desorption
TD-30 Thermal Desorption
Shimadzu has released the TD-30 series of thermal desorption systems. These are pretreatment units for gas chromatographs (GC) and gas chromatograph mass spectrometers (GCMS).
In addition to maintaining the excellent basic functionality of the previous model, this series offers significantly improved durability and processing ability. A proprietary approach has been adopted for the flow line and tube heating mechanism. As a result, a wide range of components, from low to high boiling point components, can now be accommodated. The series consists of two models. The midrange TD-30 model can accommodate up to 60 samples. The high-end TD-30R can accommodate 120 samples, and is capable of recollection and the addition of internal standard substances.
Background to the Development
A thermal desorption system is a pretreatment unit in which a tube that concentrates volatile components is heated, and the volatile components from the tube are loaded into an analytical instrument with high sensitivity. It has been used for the analysis of toxic substances in the atmosphere and substances responsible for sick house syndrome included in building materials and interior materials. In recent years, automotive interior materials and electrical equipment materials have been added as targets of analysis, and the detection of compounds with a wide range of boiling points is required. In response to such needs, Shimadzu developed the TD-30 series, which can accommodate components from low to high boiling points. As pretreatment units for GC and GCMS, they are intended for a variety of analysis targets, including toxic atmospheric pollutants, flavor components in food products, the air in clean rooms, and unusual odors from products.

Technical specifications
Inert Lines
The TD-20 uses Silcosteel-treated material to provide inertness for all tubing in contact with gases to inhibit adsorption and decomposition.
48-Sample Autosampler
The TD-20 includes an autosampler capable of holding up to 48 sample tubes. Therefore, data can be collected during night or weekends by batch processing in automatic operation mode.
Fully compatible with Automated Analysis
TD-20 analytical conditions can be set via software which is linked to the GCsolution or GCMSsolution workstation. It allows not only serial analyses using batch processes, but also changing analytical conditions of TD, GC, or GC/MS while serial analyses are still being performed.
Exceptionally Easy Maintenance
Maintenance tasks on the TD-20, such as replacing the O-ring seals for the secondary trap or the sample tubes, can be performed from the front of the instrument, making maintenance a breeze. Even if the transfer lines or other areas exposed to sample gases are contaminated by concentrated samples, the tubing sections can be replaced individually.
High Recovery Rates
Results from Measuring N-Alkanes (C16 to C36)
The efficient heating system of Shimadzu TD-20 to provide uniform heat distribution can measure highly concentrated samples almost without carryover or contamination problems and there are almost no carryover or contamination problems, even after measuring highly concentrated samples.
High Boiling Point Substances and Low Concentration Substances
The TD-20 leaves almost no residues, even for phthalic esters with high boiling points. Linearity of calibration curves is very high and repeatability for low-concentration samples is also good.
