摘要：
A photometric apparatus (100) for small sample volumes comprises a cell body (102), a light input means (104) arranged adjacent to a first surface of the cell body (102), a light source (105) emitting light of predetermined wavelength or wavelength range through the light input means (104), a light output means (106) arranged adjacent to a second surface of the cell body (102) opposite to the first surface, a light detector (107) arranged adjacent to the light out put means (104), and a flow channel (108) formed in the cell body (102), wherein surfaces of the walls of the channel (108) have a roughness smaller than the predetermined wavelength.
