Product Introduction:

Volume 3 of the International Chemical Safety Manual and the International Chemical Safety Card indicate that long-term or repeated ingestion of large amounts of melamine may have an impact on the kidneys and bladder, leading to the formation of stones. Criminals have mixed milk powder containing melamine, causing many infants to develop kidney stones and resulting in serious consequences. The liquid chromatography instrument produced by Tianpu Instrument is used for the detection and analysis of milk and dairy products containing melamine in food, as well as for the detection and analysis of melamine in milk powder, gluten powder, rice protein, corn protein, and soy protein, accurately determining the content of melamine. The instrument complies with national standards《GB/T 22388-2008Method for detecting melamine in raw milk and dairy products《GB/T22400-2008Rapid detection of melamine in raw milk by liquid chromatography. Main performance characteristics of the instrument:

1The entire system consists ofP3000High pressure pumpUV3000Composed of detector, injection valve, solvent tray, chromatographic column, working software, etc; Installation, debugging, and usage are all very simple.
2、P3000High pressure infusion pump is usedCPLDA high-precision infusion pump system with technology as the core and controlled by a microcontroller. The all digital frequency generation system, advanced motor drive system, and user-friendly human-machine display interface make operation very convenient. The advanced pump head and single valve design ideas integrate the most advanced experience in the world today, ensuring the accuracy and repeatability of infusion under various conditions.
3、UV3000It is a type of spectrophotometer that can be matched with any infusion pump and is widely used in fields such as chemical analysis, pesticides, pharmaceuticals, and chemical engineering. Adopting a fully digital and highly integrated design concept, greatly reducing the noise of the instrument; Based on digital signal transmission and processing, the signal of this detector can be directly input into the serial port of the computer for acquisition, completely eliminating the data acquisition card that traditional instruments must use!
