Abstract:
PROBLEM TO BE SOLVED: To provide a measuring cell holding mechanism capable of preventing movement of a flat surface on which a ligand of a measuring cell at a measuring time is immobilized, and preventing deformation of a passage member, and a biosensor equipped with the measuring cell holding mechanism. SOLUTION: Prism pressers 26K and a passage presser 26L are provided on the under side of a pressing plate 26I. Two prism pressers are provided on positions corresponding to pressing holes 46F formed on a holding member 46 of a sensor stick 40, and can abut on a prism part 42A by being inserted into the pressing holes 46F. The passage presser 26L whose base end part is fixed to a plate member 26H is constituted of a plate spring which is elastically deformable in the Z-direction. The plate spring of the passage presser 26L abuts on a boss 46E, thereby pressing the boss 46E with a pressing force weaker than a pressing spring 26F. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PURPOSE:To determine quantitatively and exactly endotoxin in a short period from a preliminarily obtd. calibration curve by measuring the time until the ratio between the max. quantity of the transmitted light after mixing of plural samples each mixed with an endotoxin gelation reagent and the quantity of the transmitted light decreasing with time attains a specified value. CONSTITUTION:The samples prepd. by adding a limulus amebocyte lysate (abbreviated as LAL) as the endotoxin gelation reagent to >=2 liquids to be tested are put respectively into cuvettes 1 to measure the endotoxin in raw material water for injections, etc. and the washing water, etc. during the process of production. Light is irradiated from a light source 5 to the respective cuvettes 1 by using a device which has many curvette holders 7 and can hold the cuvettes at a constant temp. The time until the ratio between the max. quantity of the transmitted light after mixing and the quantity of the light decreasing with time attains the specified value is measured by a detector 6 such as a photoelectric cell. A switch 8 for instructing the start of the measurement, an LED 9 for displaying the condition, an LED 10 for discriminating and displaying the gelation, an LED 11 for displaying the gelation time, etc. are provided to the device and the result of the measurement is displayed or recorded by a printer. The exact and simultaneous measurement of a trace amt. of the endotoxin in the many samples in a short period is thus made possible.
