| 摘要 |
The invention relates to a method and apparatus for detecting elution of a sample from a sample substrate (16) to incubation buffer (15) contained in a sample well (14) while the sample substrate (16) is still within the well (14). The method comprises measuring light (11) absorption of the contents of the sample well (14) at a predefined wavelength or wavelength range, and determining, based on the absorption measurement, the degree of elution of the sample. According to the invention, a wavelength or wavelength range is used which is absorbed by at least one elutable component of the sample but transmitted by the sample substrate (16). The invention provides a reliable way of determining the degree of elution of blood samples in neonatal sceening, for example. |
