ABSTRACT. We compared the common methods of chlorophyll measurement in Lemna minor (duckweed), Potamogeton crispus, and Egeria densa in an attempt to identify an optimal protocol to quickly measure chlorophyll in aquatic plants. Three physical processes including grinding-settling (GS), grinding-elution (GE) and immersing (IM) were compared for chlorophyll …
The elution rate may be accelerated by adding 10% alcohol at temperatures around 60 to 80°C with a stripping time of 4 to 6 hours. The elution of loaded carbon may also be speeded by using pressure elution (120 to 130°C at 70 psig) in 6 to 8 hours …
Base elution in ammonium hydroxide or ammonium phosphate provided optimal specificity and recovery of phosphorylated peptides. In contrast, elution with phosphoric acid gave incomplete recovery of phosphopeptides, whereas inclusion of 2,5-dihydroxybenzoic acid in the eluant introduced a bias against the recovery of multiply phosphorylated peptides.
