WM-CN100, 50mx0.25mmx0.2µm

The WM-CN100 GC capillary column 50mx0.25mm, 0.2µm, is a highly polar speciality column for fatty acid analytics and is offered in 50 and 100 metre lengths with a very thin film of 0.2 µm.The long separation path length is the prerequisite for fully resolving saturated, mono- and polyunsaturated esters and their cis- and trans-isomers in a single run.The exact phase composition is not published; its suitability, however, is documented by test reports. WM-CN100 is used particularly for the determination of 37 fatty acids according to GB 5009.168-2016 and of trans-fatty acids according to GB 5009.257-2016.

Features and Benefits

• Nonpolar to highly polar
• WCOT and PLOT versions
• Individual performance testing for each column

Additional Information

The WM series is the high-performance line of the gas chromatography product portfolio and covers demanding routine, GC-MS, and specialty applications. The MS variants feature the same phase chemistry as their respective base phases but are manufactured to stricter specifications, with dedicated surface deactivation and a lower desorption rate. In addition to the classic polysiloxane and wax phases, the series includes application-specific columns tailored to a single analytical method. In PLOT columns, adsorption strength and carrier gas velocity determine the separation, and water in the carrier gas shifts the retention.
