Ultra-high capacity for the contaminant of interest; either Moisture, Hydrocarbons, Oxygen, Sulfur and Mercury. For applications with a single contaminant of interest, high capacity contaminant specific traps are your best option, since they generally have four times as much capacity for the specific contaminant as a purifier. This translates to a capacity that exceeds twelve standard type "A" tanks of gas or the equivalent of over 300,000 liters of gas at standard temperature and pressure.
