ABSTRACT:
Endotoxin contents in samples can be determined qualitatively, or quantitatively, singly or in parallel, with high precision in a short time by a process comprising applying a light to each sample solution, measuring an initial transmitted light amount I.sub.0 and a transmitted light amount at a time t, I(t), to give a ratio R(t)=I(t)/I.sub.0, and judging a gelation point by a threshold value of R(t), or further obtaining a gelation time from the gelation point. An apparatus used therefor is also disclosed.
