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.\u003c\/p\u003e\r\n\u003cp\u003eIn 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.\u003c\/p\u003e\r\n\u003cp\u003eThe 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.\u003c\/p\u003e\r\n\u003ch3\u003eBTR-CW, OXYGEN-RESISTANT PHASE:\u003c\/h3\u003e\r\n\u003cp\u003eColumns coated with bondable PEG and, even more so with traditional Carbowax 20M, deteriorate in the presence of oxygen. It has been necessary, therefore, to maintain an oxygen-free chromatographic system. To lower the costs of maintaining such a system and to improve the chromatographic properties of the PEG-type columns, we offer the oxygen-resistant BTR-CW phase type. BTR-CW is a polyethylene glycol (PEG) phase, similar to our 007-CW phase, but which incorporates an anti-oxidant moiety to better withstand oxygen exposure and the resultant degradation. The BTR-CW also offers increased thermal stability and longer column lifetimes.\u003c\/p\u003e\r\n\u003cp\u003e007-CW\/BTR-CW, Polyethylene Glycol (PEG) columns are available in all standard column I.D.'s and lengths.
