Automated sequential injection analysis systems for the determination of trace endotoxin nu00ecveis

摘要

"Automated sequential injection analysis systems for the determination of nu00ecveis trace endotoxin.A system (10) is described and the method used to detect the presence of endotoxin in a sample of fluid.The system (10) includes a pump to release a bi-directional fluid (20) to enter, move and mix fluids within the system (10).The system (10) also includes a component for containment of fluid (50) in fluidic communication with the pump to release fluid (20).Fluid, including a sample of test fluid, the reagent LAL and segments of fluid of chromogenic substrate.Are sucked to the component of containment of fluid (50) in response to the operation of the pump to release fluid (20).After being mixed, these fluids are delivered to a part of a cell of the detector (105), a detector (100).Where a light from a light source (150) is introduced in the cell of the detector (105).The light of the cell of the detector (105) is collected and compared with light from the light source (150) to determine whether endotoxin is present in the sample fluid.After the mixed fluids are delivered into the cell of the detector (105), the washing fluid introduced to clean the system (10).Air is also introduced into the system (10) in order to remove the washing fluid within the system (10).
