  • Method and apparatus for handling samples and sample collection system
    Patent number: 5460057
    Abstract: Method for handling blood samples (32) wherein a blood sample is absorbed into a filter paper (30) and a sample piece (36) is taken from the filter paper from the opposite side of the absorption side. The sample piece is placed in a sample well of an uncoated micro titration plate (45) and is dissolved in a liquid so that a sample solution is formed in the well. The sample solution is transferred to a second micro titration plate (52-54) coated for the analysis. The apparatus comprises a camera (43), which identifies the filter paper (30), locates the blood sample (32), and informs the punch (47) of the location of the sample. The filter paper (30) is placed in a package, (22) having openings (25) for absorbing and punching of the sample and the covering (23) is provided with a bar code (29).

  • Method for the correction of a counting error in liquid scintillation counting
    Patent number: 5173607
    Abstract: A method for correction of the counting error in liquid scintillation counting in the attenuation of light passing through a sample solution is measured before or after the actual liquid scintillation counting takes place. By means of the attenuation measurement the error in the liquid scintillation counting result, caused by the colorness of the sample solution, and/or by the counting apparatus, is corrected. The apparatus has a liquid scintillation counter provided with cylinder shaped optics. A photometer is incorporated in the liquid scintillation counter. By means of the photometer, the attenuation of light passing through the sample solution is measured before or after the actual liquid scintillation counting measurement, where said attenuation is caused by the colorness of the sample solution and/or due to features of the apparatus.
