The Laser Line Long path gas cell is a variable pathlength cell with a battery operated visible laser alignment system. The cell features a borosilicate body, SS valves and fittings with 1/4” Swagelok® connections and flow tube.

The Long Path Absorption Spectrophotometer Cell is for IR/FTIR analysis of dilute solutions or solutions that absorb weakly. The cell has been found to be particularly useful in hydrocarbon testing, such as testing for the presence of oil in water, conforming to EPA methods 418.1 and 413.2.
