15 CM Cell

CUSTOM 15 CM GAS CELL

This 15 centimeter gas cell has a longer pathlength and fits in most FTIR spectrometer sample compartments.   This added length provides lower detection levels than a 10 cm, 5 cm, or 1 cm cells and still works well in measuring down to about 15 ppm for most high IR absorbing gases in modern FTIR spectrometer using a DTGS detector.

We have a number of people using to measure very active gases.  The gas cell is made of 316L stainless steel, welded 1/4” VCR fittings,  CaF2 windows in lieu of KBr windows and Teflon or Kalrez o-rings in lieu of Viton o-rings.  These people are measuring impurities in pure fluorine or HF for example.  Other materials maybe used to better match other active gaes chemical properties.

 

MERC-0.1L/15 CM-VCR

Mercury Series Single Pass Gas Cell.  Baseplate and mounting fixture for center-focus FT-IR or external beam applications.  Sample line connections 1/4” SS welded VCR fittings.  Comes with two 37.5 mm x 4 mm, KBr windows and Teflon O-rings.  Optional purge tubes may not fit and depends on sample compartment.
