The Long Path Absorption 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 with EPA methods 418.1 and 413.2. The Long Path Absorption Cell is much more versatile than the standard glass cylindrical cell with permanently fused quartz windows. The windows can be changed by the user without the need to replace the cell or the cell can be factory reconditioned. Cell lengths are 5, 10, 25, 50 and 100mm. Other lengths can be supplied. 22mm x4mm crystal windows are utilized to minimize replacement costs.
