WM-TVOC, 50mx0.32mmx1µm

The WM-TVOC GC capillary column 50mx0.32mm, 1µm, is tailored to the determination of the total content of volatile organic compounds in indoor air. The design targets a wide retention window that captures very volatile and less volatile components in a single run.In addition to the long versions, short formats are documented that deliver eight substances baseline-separated in less than ten minutes and are therefore suitable for portable instruments.WM-TVOC is used particularly for the aggregate and individual determination of volatile organic compounds in indoor air, emissions and material samples.

Features and Benefits

• High-performance columns with low bleed
• Standard, MS, HT, and specialty phases
• 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.
