Carrier gas purifier
The use of carrier gas purifiers is recommended with any analytical system to avoid contamination with hydrocarbons, oxygen and/or water. These are typically purchased and installed at the point of GC–MS setup, and should be monitored and replaced routinely. Markes recommends a helium purifier when using BenchTOF.
- Helium purifier contains multiple sorbents for removal of various contaminants
- Packed under helium to prevent off-gassing
- Sits in-line, and connects with 1/8″ Swagelok fittings

To enable optimal performance of the most sensitive GC–MS instruments, ultra-high purity helium is required. Markes recommends a speciality helium purifier when working with BenchTOF in order to remove oxygen, water, hydrocarbons, carbon dioxide and carbon monoxide, giving an output gas that is 99.99999% pure.
The maximum flow capacity is 8 L/min and the stated life is 13 standard cylinders of 99.999% helium (when the level in the incoming gas does not exceed 10 ppm). The maximum pressure is 250 psig.
