Product Introduction:

In recent years, feed additives“auxin”“Protein essence”Frequent incidents have seriously endangered the safety of animal food, therefore, feed safety has become a hot topic of concern for the general public and has attracted the attention of relevant national departments. The National Regulations on the Administration of Feed and Feed Additives2012year5moon1dayAfter the formal implementation and subsequent approval of the "License Conditions for Feed Production Enterprises" and "License Conditions for Mixed Feed Additive Production Enterprises", our companyHongxiang Analytical InstrumentreferenceGB/T 17819-1999The standard has been developed501Determination of vitamins in vitamin premix by series high-performance liquid chromatographyB12The method.501High performance liquid chromatography is suitable for vitamin premix and vitaminB12Vitamins in pre mixed preparationsB12The measurement. The detection range is vitamins per kilogram of sampleB12Content greater than0.25mg,The results are accurate and reliable, with good detection limits, widely applicable for the determination of various vitamins, amino acids, and toxic and harmful substances in compound feed, concentrated feed, compound premixed feed, and premixed feed. You passed smoothlyGMPCertification system acceptance is one of the standard instruments that comprehensively ensures feed safety.

The instrument adopts a high-pressure constant current pumpCPUControlled reciprocating double plunger rod series pump head and patented design“Floating pump plunger rod sealing ring”Technology has achieved two crucial functions for users:①Automatic emptying ②Automatic cleaning. Effectively extended the service life of the plunger rod and sealing ring. There are various types of pump heads available for analysis, semi preparation, and preparation for users to choose from. The pump head is external, and all components are easy to replace and maintain. It has a complete pre cleaning function, making it easy to quickly replace solvents. It has flow system error compensation, high and low pressure protection, and alarm functions.RS-485External communication interface design, which can be controlled externally by a workstation, and the workstation can display various parameters during pump operation in a timely manner.
