Supplier: VWR International

Application specifc columns for volatile organic compounds (VOCs), solvents and purgeable compounds. Due to the high maximum 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.
