Pan-1 was seeded in different types of water at a concentration of 220 PFU/ml. Adsorption of Pan-1 to a 1MDS filter was determined by comparison of Pan-1 titers in the water, as determined by PA, before and after passage through the filter. The recovery rate was determined by dividing the Pan-1 titer in the eluate by the titer seeded. The elution rate was calculated based on the Pan-1 titer in the eluate relative to the estimated amount of Pan-1 adsorbed to the filter. In the case of deionized, finished, and ground water samples, the adsorption rates were estimated to be 99%. Viruses were eluted with 3% BE (pH 9.0).
