Gas Cells for FTIR Sampling
Short pathlength cells are useful for measuring higher concentration gas samples. Firebird Optics gas cells can be used on samples with concentrations of 100ppm and above. These cells are airtight and made for extreme pressure applications in excess of 1 x 10-8 Torr.
Type TGC-10 PTFE FTIR Gas Cell (Lightpath: 100mm)
Type TGC-10 PTFE FTIR Gas Cell (Lightpath: 100mm)
The TGC-10 is a cell where all components of the cell that contacts the sample are made from PTFE. This is helpful for any sample that could corrode or be corroded by Optical Glass, Fused Silica or Stainless Steel. This type of cell is most helpful in qualitative analysis applications where one or more gasses are present in concentrations of more than 5%.
This cell can be used in high pressure and temperature applications where glass/quartz spectroscopy samples are impractical. If you are interested in Optical Glass and UV Quartz versions of this cell, check out the Type 34 from our friends at FireflySci. They rock.
This assembly can be fitted with Firebird Optics high grade optical windows and snapped into any commercial FTIR spectrophotometer.
Can either be ordered as an empty assembly or with a pair of 38x6mm undrilled optical windows.
There is currently a leadtime of 2-3 weeks.
