Dual regulator pneumatics accessory
TD equipment typically requires a supply of high-purity carrier gas (usually helium) and a supply of dry gas (either air or nitrogen). The dual regulator pneumatics accessory controls both these gas supplies immediately upstream of the TD system.
It consists of a high-quality stainless steel regulator (0–60 psig) for control of the carrier gas, and a standard regulator (0–100 psig) for control of the dry gas. Both lines also have on/off toggle valves.
Markes strongly recommends that all thermal desorbers are configured with a dual regulator pneumatics accessory.
Single regulator pneumatics accessory
The single regulator pneumatics accessory consists of a high-quality (stainless steel) regulator (0–60 psig) and an on/off toggle valve. 
It is recommended for use in the following configurations:
- Controlling purge gas supply on ULTRA-xr and TD100-xr autosamplers with internal standard functionality.
- Regulating the pressure of internal standard gas if no other appropriate regulation is supplied.
- Controlling the supply gas to the Micro-Chamber/Thermal Extractor, TC-20, and Calibration Standard Loading Rig.
