Apparatus and method for absorbance detection |
摘要 |
An apparatus and method for absorbance detection in instrumental situations which have short absorption path lengths, such as microchip type devices, includes modulating the sample beam incident upon a sample cell to improve the sensitivity of the absorbance measurement. The modulation means includes a scanning device arranged to move the sample beam from a first position in which the sample beam is incident upon the sample area to a second position in which the sample beam is incident upon the cell.
