The G-2 Gas Cell is for analysis of pure gases or gas mixtures in which component gases are present at concentrations of 5 percent or more. The G-2 Gas Cell has a fixed pathlength of either 5cm or 10cm. The windows of the cell are easy to remove for cleaning, making the G-2 ideal for working with wet or reactive gases that have a tendency to fog or attack the window material.

The G-2 cell comes completely assembled in a stainless steel universal 2” x 3” mount. It includes a Pyrex® glass body, silicon rubber or Viton® gaskets and a choice of optical materials. The window size is 38mm x 6mm. The clear aperture of the cell is 32mm.

The G-2 is available in a variety of optical window materials, two pathlengths and a choice of ground tapered endings with 12/30 joints (TPE), plain endings joints (PTE) or ground semi-ball joints with 18/9 joints (SBJ). (See notes beneath chart and diagram).

PTE = Plain tubular endings. This is a straight tube, not ground.
SBJ = Semi ball ending with 18/9 joints. This is not a ground joint, 18mm dia. at widest with 9mm hole.
TPE = Tapered ending with 12/30 joints. This is a ground joint, 12mm dia. at widest, 30mm in length.
