Example 1

The utility model provides a medicament composition detects sample cell with contrast effect. As shown in fig. 1, the reagent component detection sample cell with the comparative effect includes a standard sample chamber 1 and a sample chamber 2 to be detected. The standard sample chamber 1 is a cuboid, the sample chamber 2 to be detected is a cuboid, and the standard sample chamber 1 and the sample chamber 2 to be detected are arranged in parallel. The ultraviolet light is irradiated perpendicularly to the side wall of the standard sample chamber 1 to reduce reflection of the ultraviolet light. A partition plate is arranged between the standard sample chamber 1 and the sample chamber 2 to be measured. That is, the partition plate divides the entire chamber into the standard sample chamber 1 and the sample chamber 2 to be measured. The standard sample chamber 1 is used for containing a standard sample, and the sample chamber 2 to be tested is used for containing a medicament sample to be tested. The ultraviolet absorption spectrum of the standard sample is known in advance. The top of the sample chamber 2 to be tested is provided with a sample chamber opening 3 to be tested for filling a medicament sample to be tested. The side walls of the standard sample chamber 1, the side wall of the sample chamber 2 to be detected and the partition plate are made of quartz so as to reduce the absorption of ultraviolet light.

During application, the ultraviolet light beam simultaneously passes through the standard sample chamber 1 and the sample chamber 2 to be detected, and because a sample in the standard sample chamber 1 is different from a medicament sample in the sample chamber 2 to be detected, and the ultraviolet absorption spectrum of the medicament sample to be detected is different from that of the standard sample, the medicament component to be detected in the sample chamber 2 to be detected is determined according to the difference between the ultraviolet absorption spectrum to be detected and the ultraviolet absorption spectrum of the single standard sample. The utility model discloses left out the step of changing sample cell or changing sample cell in the sample cell, operating procedure is few, and is efficient, has good application prospect in the ultraviolet absorption spectrum of medicament composition surveys.

Furthermore, the partition plate is movable to adjust the volume of the standard sample chamber 1 and the sample chamber 2 to be tested, so as to meet the detection requirement that the ultraviolet light beam can pass through the standard sample and the sample of the reagent to be tested. For example, when the amount of the drug sample in the sample chamber 2 is small, the partition plate is moved toward the sample chamber 2 to increase the liquid level of the drug sample.
