Application of Porous Layer Open Tubular Columns: Beyond Permanent Gases

Porous layer open tubular (PLOT) columns are traditionally built with particles that adhered to the tubing walls. These have unique selectivity and provide a great alternative when gaseous samples need be separated, but these also been used separate higher boiling point analytes. There many different commercially available stationary phases of PLOT columns, including alumina-based molecular sieves, porous polymers. Alumina-based an aluminum oxide phase is then deactivated salts. high capacity, superior loading ability, produce symmetrical peaks. Molecular sieve designed specifically for permanent gas separations because retention. polymer highly hydrophobic, making them more applicable analyzing wider range samples.
