Autosampler
The Fusion has a standard 40mL vial, 75-position integrated autosampler with arobotic arm and carousel for position selection.
UV Oxidation Reactor
The UV reactor is composed of a glass vessel and a UV light source. The Fusion introduces the sample and persulfate reagent into the UV reactor. The persulfate reagent, combined with UV light, oxidizes carbon in the sample. Teledyne LABS’ improved UV reactor increases sample conservation and improves radiation interaction with water samples and oxidant.
Halogen Scrubber
The detector, which measures CO2, can be affected by halogens. To prevent analytical errors, the halogen scrubber removes chlorine and other halogens from the CO2 before it enters the detector.
Septum Piercing Needle
allows for the use of vial caps with a septa thus eliminating sample exposure time to the atmosphere
Syringe and Valve
The syringe driver is a precision measuring instrument that draws in and dispenses fluid. The syringe driver has a volume delivery range of 125µL to 25mL and sample delivery between 2mL and 10mL depending on the applied method
Moisture Control System (MCS)
Consists of a mist trap and
permeation dryer, both of which are designed to remove moisture from the sample. After oxidation of the sample, carrier gas sweeps CO2 and water vapor out of the UV reaction chamber. Next, the CO2 travels through the mist trap, where most of the moisture is collected and removed. The gases then travel to the permeation dryer, which removes the rest of the moisture from the sample gas.
IC Sparger
- glass fritted vessel that holds the sample while purging the Inorganic Carbon (IC) out of the sample and preparing it for analysis. After the addition of acid, purge gas flows through the sparger, removing the IC from the sample. The Fusion can report IC for both IC only and TC-IC modes, or vent it into the atmosphere while in the TOC mode.
