Abstract
An optical sample characterization method is disclosed comprising: holding a sample in a sample container proximate at least one two-dimensional detector array assembly, wherein the sample container has a first end and a second end; setting up a gradient between the first end of the sample container and the second end of the sample container; illuminating the sample between the first end of the sample container and the second end of the sample container; and detecting light received from the illuminated sample from the first end of the sample container to the second end of the sample container by the two-dimensional an-ay assembly.

(canceled)
An optical sample characterization instrument, comprising:
- a sample holder,
- a first illumination source positioned to illuminate the sample in the sample holder,
- a second illumination source positioned to illuminate the sample in the sample holder,
- a first two-dimensional detector array positioned to detect light from the second illumination source that is transmitted through and not absorbed by the sample, and
- a second two-dimensional detector array positioned to detect light scattered by the sample from the first illumination source.
An optical sample characterization method, comprising:
- supporting a sample in a sample holder proximate at least one two-dimensional detector array assembly,
- illuminating the sample,
- detecting light received by a first subset of the detectors in the array assembly,
- deriving information about a first characteristic of the sample based on the light detected by the first subset of the detectors,
- detecting light received by a second subset of the detectors in the array assembly, and
- deriving information about a second characteristic of the sample based on the light detected by the second subset of the detectors.
An optical sample characterization instrument, comprising:
- at least one two-dimensional detector array assembly;
- a sample holder for supporting a sample proximate the at least one two-dimensional detector array assembly,
- a light source for illuminating the sample,
- wherein the instrument is configured to:
- i) detect light received by a first subset of the detectors in the array assembly and to derive information about a first characteristic of the sample based on the light detected by the first subset of the detectors, and
- ii) detect light received by a second subset of the detectors in the array assembly, and to derive information about a second characteristic of the sample based on the light detected by the second subset of the detectors.
