To use the receiver as a mechanism capable of automatic change, there are methods such as counting the number of drops by means of a photocell, a quantitative siphon, or the use of a scale. The method of changing the receiver at certain intervals is used for a certain rate of solution separation.
In scientific research, medical treatment, colleges and universities and laboratories of factories and mines and other relevant departments for liquid column chromatography analysis, this instrument can automatically collect the chromatographic solution in portions, thus replacing manual operation and improving work efficiency.
Ultraviolet nucleic acid protein detector is the main device of chromatographic analysis, ultraviolet detector with chromatographic column, constant flow pump, part of the collector (according to the need for optional) and computer printing equipment that constitutes a complete set of liquid chromatography separation of chromatography system. UV detector is now engaged in life science research, drug determination, chemical, food science and medical research and other industries of modern analytical instruments. UV detector is widely used in industry, agriculture, scientific research and universities and colleges of scientific research and teaching experiments. Its principle is based on the material (sample) on the ultraviolet light has a significant absorption characteristics, to achieve the content of the sample content comparison analysis, in order to carry out the sample protein, nucleic acid material identification detection and content determination.
