Description

technical field [0001] The invention relates to a catalyst rapid screening device, in particular to a multi-channel ultraviolet absorption method rapid screening catalyst device. Background technique [0002] With the gradual development of combinatorial chemistry to the field of catalysis, the synthesis speed of catalyst libraries is getting faster and faster. To evaluate the performance of these catalysts requires high-throughput instruments and methods, and requires the development of high-throughput screening technologies. Ultraviolet absorption spectroscopy is widely used in analytical chemistry. It has been reported for the detection of various inorganic and organic molecules, and has become an important analytical tool. Ultraviolet absorption method has the characteristics of fast analysis speed and low sample consumption, and is suitable for many channel analysis. [0003] Chinese patent application (publication number CN1340160A) discloses a rapid screening method ...
