Detection Limits: 3.1 Ambient water reporting limits: chlorophyll a - 5.0 g/L, pheophytin - 3.0 g/L 3.2 Laboratory reporting limits: chlorophyll a - 5.0 g/L, pheophytin - 3.0 Webchlorophylls, which are more polar than -carotene is slight: chlorophyll a has a methyl group (Y=CH 3) in a position where chlorophyll b has an aldehyde (Y=CHO). This makes chlorophyll b slightly more polar than chlorophyll a. Pheophytins are chlorophyll molecules without the Mg2+-ion and two nitrogen atoms protonated instead
