General purpose low to mid polarity phase for a wide range of applications, including (for example): Aroclors, pesticides, herbicides and more.

Supplier: Avantor

Proprietary low-polarity and low-bleeding stationary phase; great choice for pesticides, herbicides, polychlorinated biphenyls (PCBs), and polyaromatic hydrocarbons (PAHs). Ideal for GC/MS applications and is also an excellent choice as a confirmation column for semivolatile environmental analysis.

Supplier: Avantor

Application specifc columns for volatile organic compounds (VOCs), solvents and purgeable compounds. Due to the high max. temperature, they are ideal for two-parallel columns confg. in the same oven. A good alternative to the HI-624 giving different selectivity. It is a more robust than the HI-624 and can operate at higher temperatures.

Supplier: Avantor
