Quadrex GC Column Quadrex BTR-CW, 50 m x 0.25 mm ID, 1 μm film

Name: Quadrex GC Column Quadrex BTR-CW, 50 m x 0.25 mm ID, 1 μm film
Brand: Quadrex

007-CW and BTR-CW are the Quadrex designations for an ethylene glycol/siloxane copolymer. This polymer can be used to separate compounds at temperatures not normally associated with polyethylene glycol (PEG, Carbowax™) phases. Both the lower and upper temperature limits of traditional Carbowax type columns are extended with this phase.In addition, Quadrex offers a modified version of the 007-CW phase, designated BTR-CW, which incorporates an anti-oxidant moiety to better withstand oxygen degradation. The BTR-CW phase offers increased thermal stability and longer column lifetimes. See additional information below.The hydrogen bonding interactions of the 007-CW and BTR-CW phases makes them well suited for the analysis of polar compounds such as solvents, flavors, perfumes, and essential oils. These phases are not recommended for the analysis of mixtures containing silylating reagents. Comparable to Carbowax 20M. Similar phases are DB-Wax, Stabilwax, AT-Wax, HP-20M, HP-Innowax,Mostra di più
