Method and apparatus for separating and measuring the amount of the glycosylated hemoglobin fractions in a blood sample. The method and apparatus provide a means for lysing sample red blood cells and, in the same container, separating the glycosylated hemoglobin fractions from the other residual hemoglobin fractions through the utilization of a polymeric material.
摘要:
An apparatus for securing assembly plates in washing or spraying installations of heat exchangers, particularly cooling towers, with at least two layers of vertical assembly plates, with the layers being disposed one above the other and the assembly plates in each layer, respectively, being arranged parallel to one another, and from layer to layer at a predetermined spacing as well as at a predetermined angle with respect to each other. A spacer is arranged diagonally to the angularly crossing assembly plates, which spacer is provided with lower and upper guide slots under the circumstances oriented at half the crossing angle with respect to its longitudinal extent. The guide slots of each set run parallel to one another. The upper and lower guide slots respectively run in the crossing angle relative to each other and have contact surfaces respectively formed spaced apart corresponding to the predetermined spacing of the assembly plates of the layers which are disposed one above the other.
