HT2800T: All-in-one GC Autosampler
The HT2800T is a multipurpose sampler that can perform liquid, headspace, and SPME injections. It can be mounted on any GC or GCMS model, and be operated with ease. The colour display will guide the user to the operating steps.
Note: Shimadzu (Asia Pacific) only offers models HT2800T and HT2850T of HTA Autosamplers in our region.

Key Features
Easy to use
For routine analyses, the HT2800T features one-touch operation. After loading the sample, you just need to enter a range of vial numbers and push the START button. The full-color touch screen interface provides easier system accessibility and usability.
5+5
The HT2800T takes 5 minutes to switch between modalities and 5 minutes to move between GCs. The HT2800T allows for quick and easy switching from one application to another on the same GC workstation. Regardless if your samples are processed in headspace, liquid, or SPME mode, or if the method requires split, splitless or on-column injection, your new instrument set-up is ready in a few minutes.
Smart Technologies
The HT2800T benefits from a unique portfolio of patented, proprietary or licensed technologies that have been put together by our R&D team to make your user experience amazing. For your headspace analysis, we provide system integrity test and vial leakage check functionality. For your liquid sample analysis, HT2800T features the innovative SyringeID, which is able to identify syringes in a univocal way. It prevents syringe volume mismatch error and keeps track of the syringe consumption.
SPME Superior thermal stability
The HT2800T supports the derivatisation pre- and post-extraction, as required by different SPME applications. The extraction is carried out in the heated and shaken oven. The possibility of setting the shaking speed to very low allows for the minimisation of mechanical stress on the fiber. The oven cover is kept closed during the extraction phase, whihc is very important to ensure temperature homogeneity, especially if the extraction time is very long.

Other Sample Introduction Systems
Dynamic Headspace
The dynamic headspace method, also known as “purge and-trap”, is a more sophisticated form of headspace injection which can achieve greater accuracy than SHS. Firstly, a large known volume of inert gas is introduced into the liquid sample, “purging” the sample. The volatile target analytes are swept into an absorbent trap connected to the sample vial. Then the absorbent trap is heated, releasing the volatile analytes into the GC-MS system.
Thermal Desorption
In this method, a portable sampling pump is used for field collection of large volumes of gas in thermal desorption (TD) tubes filled with trap sorbents. Volatile analytes are released from these tubes into the GC-MS via heat desorption using an adsorbent trap system. A good trap system has to be able to accommodate a variety of TD tube types while also allowing optimized desorption conditions for each analyte to ensure precise chromatographic data.
Direct - Thermal Desorption
Direct thermal desorption is used for solid samples rather than gaseous samples as in normal TD. The TD tubes are filled directly with the solid material rather than sorbents. Heating the tubes releases volatile analytes via thermal desorption. These analytes may be introduced directly into the GC-MS or pass through a trap sorbent as in the TD system above.
Direct Sample Injection
Direct sample injection is used for small solid or liquid samples that can fit into a small sample cup. The cup is attached to a heating probe and can be inserted directly into the GC-MS ionisation chamber without passing through a GC column. The sample is ionized through heating. This is a useful option for less volatile or non-volatile analytes that are not suitable for GC separation.
Pyrolysis
Pyrolysis is a unique approach to the analysis of less volatile or non-volatile compounds in liquid or solid samples. The sample is rapidly heated to 600-1000 ºC, releasing smaller, more volatile decomposition products that can be separated and analyzed by GC-MS. The chromatograms/pyrograms obtained in this way can be used as chemical “fingerprints” . Individual mass spectra are used for quality control and component identification.
