Often specified in EPA and ASTM methods for the analysis of hydrocarbons in water after a Freon extraction, these cells are ideal for obtaining spectra of very dilute solutions. The cell body is made of Pyrex for inertness and strength, while Teflon gaskets provide a protective layer between the cell body and window.
Product Detail
The Long Pathlength Liquid Demountable Cell is often specified in EPA and ASTM methods for the analysis of hydrocarbons in water after a Freon extraction. These cells are ideal for obtaining spectra of very dilute solutions. The cell body is made of Pyrex for inertness and strength, while Teflon gaskets provide a protective layer between the cell body and window. The 32 mm stepped windows are held in place by retaining rings and thumbnuts. The cell is filled through the single 5/12 ground glass port on top of the cell. The kit comes complete with windows and is preassembled.
Applications • Allows analysis of low concentration components in IR-transmissive solvents • For EPA methods 418.1 and 413.2 and ASTM method D3921
Features • One piece assembly with integral slide mount • Cell is ready to use when received • Ultrasonically stepped windows for leakproof sampling • Windows are demountable and easy to remove for repolishing or changing • Pyrex body with tight fitting glass stopper prevents spills and solvent evaporation • Integral holder and other metal parts are made of both stainless steel and anodized aluminum • Kit includes cell holder, Pyrex cell body, two Teflon gaskets, two Teflon o-rings and choice of windows
