Designed for efficient separation of argon/oxygen and other permanent gases, including 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: Agilent CP-Molsieve 5A, HP-PLOT Molesieve; Quadrex PLT-5A; Supelco/Millipore Sigma Molsieve 5A.
