WebPeak height vs peak area in GFAAS. aldrayas 4 hours ago. Hello everyone, I have a customer who only uses GFAA with Zeeman correction asking why most of the methods uses "Peak height" measurement mode as he has seen that some local regulations indicate that for GFAA instruments only "Peak area" should be use. Is there some metals that would be ... WebFeb 27, 2007 · Theoretically when injecting the same sample, if reduce the flow rate by half while keep everything else same, the peak area for this compound should be unchanged, the peak is wider and lower. We observed with a mAb, both in SEC and CEX, PA increased almost linearly when reducing flow rate. Is that unusual? Thanks! tom jupille Site Admin
