Fused silica molecular sieve PLOT column produces sharp, symmetrical peaks for separation of permanent gases such as argon, oxygen, and carbon monoxide. Note: the molecular sieve material is very hydrophilic and will absorb water from the sample or carrier gas which can affect peak shape and resolution. A moisture absorbing carrier gas filter is recommended. Temperature range: -100C to 300C. Similar phases: Alltech/MEGA S.r.l.
