Method for photometrically measuring light transmitted to and through cuvettes disposed in a row

Claim 1

A method for transmitting measuring light from a single light source to and through cuvettes arranged in a row in a photometer, wherein the light emitted from said single light source is transmitted, via separate light paths at given durations, to each cuvette in said row, while the light passing through each cuvette is detected by a detector paired with said each cuvette in order to measure the amount of absorbance of said light, said method comprising, transmitting light in succession from said single light source to each cuvette in said row at substantially equal intervals; said light being controllably transmitted to each of said cuvettes by means of a light-cutting movable surface which intercepts said light paths; said surface being impermeable to said light except for the provision of a plurality of prearranged light-transmitting slots; each slot being arranged on said surface to correspond to a particular light path and corresponding cuvette, said slots being arranged parallel to the moving direction of the surface; and the measuring said transmitted light as it passes through a specified cuvette when a corresponding slot coordinates in position with a light path selective to said cuvette.

Claim 2

A method for transmitting measuring light from a single light source to and through cuvettes arranged in a row in a photometer, wherein the light emitted from said single light source is transmitted, via separate light paths at given durations, to each cuvette in said row, while the light passing through each cuvette is detected by a detector paired with said each cuvette in order to measure the amount of absorbance of said light, said method comprising, transmitting light in succession from said single light source to each cuvette in said row at substantially equal intervals; said light being controllably transmitted to each of said cuvettes by means of a light-cutting movable surface which intercepts said light paths; said surface being impermeable to said light except for the provision of a plurality of prearranged light-transmitting slots; each slot being arranged on said surface to correspond to a particular light path and corresponding cuvette, said slots being arranged parallel to the moving direction of the surface; and the measuring said transmitted light as it passes through a specified cuvette when a corresponding slot coordinates in position with a light path selective to said cuvette.

Claim 5

An apparatus for conducting measuring light successively to and through cuvettes arranged in a row in a photometer comprising a light source with a plurality of light paths coordinated therewith such as to provide a separate light path for each cuvette in said row for conducting light form the light source successively through separate light paths to and through a selected cuvette; and a detector for each of said cuvette detecting the light passing through the cuvette, said apparatus comprising a light-cutting movable surface for interpreting said light paths, said surface being movable across said light paths and being impermeable thereto except for the provision of pre-arranged light-transmitting slots disposed parallel to the moving direction of said surface, to thereby transmit light through each of a succession of slots in said surface to and through a corresponding cuvette in succession for substantially equal periods of time.

Claim 6

An apparatus for conducting measuring light successively to and through cuvettes arranged in a row in a photometer comprising a light source with a plurality of light paths coordinated therewith such as to provide a separate light path for each cuvette in said row for conducting light form the light source successively through separate light paths to and through a selected cuvette; and a detector for each of said cuvette detecting the light passing through the cuvette, said apparatus comprising a light-cutting movable surface for interpreting said light paths, said surface being movable across said light paths and being impermeable thereto except for the provision of pre-arranged light-transmitting slots disposed parallel to the moving direction of said surface, to thereby transmit light through each of a succession of slots in said surface to and through a corresponding cuvette in succession for substantially equal periods of time.
