    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 I₀ and a transmitted light amount at a time t, I(t), to give a ratio R(t) = I(t)/I₀, and judging a gelation point by a threshold value of R(t), or further obtaining a gelation time from the gelation point. An apparataus used therefor is also disclosed.

    Abstract: The invention relates to a measuring device for luminescence measurement comprising a sample carrier (8) for receiving a luminescent sample (9), a first lens array (13) having numerous lenses (14) arranged in a grid-shaped fashion and serving for focusing luminescent radiation emerging from the luminescent sample (9), and comprising a light sensor (16) for detecting the luminescent radiation emitted by the luminescent sample (9), wherein the light sensor (16) is arranged downstream of the first lens array (13) in the beam path of the luminescent radiation. It is proposed that the first lens array (13) is a first microlens array (13) having numerous microlenses (14), wherein a first perforated mask (11) having numerous holes (12) is arranged in the beam path of the luminescent radiation between the sample carrier (8) and the first microlens array (13), wherein the individual microlenses (14) and the holes (12) are assigned to one another and have corresponding axes. The sample carrier (8) can have a substantially planar waveguide (8), wherein the excitation radiation from an illumination unit (1) is coupled into a waveguide edge (10) of the waveguide (8).

    Abstract: A system and method for multimode imaging of at least one sample is disclosed. The system includes at least one light source; an optical system selected responsive to a mode of operation of the imaging system; and a detector capable of selective reading of pixels. The at least one sample is moved relative to the optical system using a sample movement technique selected from the group consisting of step sample moving and continuous sample moving. The method includes the steps of (1) selecting a mode of operation for the imaging system; (2) transmitting light from at least one light source through an optical system selected in response to the mode of operation for the imaging system; (3) moving the at least one sample relative to the optical system using a sample movement technique selected from the group consisting of step sample moving and continuous sample moving; and (4) selectively reading pixels with a detector.
