SAMPLE COLLECTION, HANDLING, AND PRESERVATION
ccal.oregonstate.eduWhatman GF/C filter papers showed that ammonia appeared to be adsorbed in the first 50 ml filtered through the GF/C filters while no adsorption was observed for the membrane filters (Riemann and Shierup 1978). In both cases, it is advisable to remove leachable materials from all filter papers (Eaton et al. 1969) by either soaking them in distilled
