Food is of paramount importance to the people, and feed is of paramount importance to animal husbandry. Whether ordinary people can eat reliable meat and drink reliable milk depends on feed. In recent years, incidents of adding "growth hormone" and "protein essence" to animal feed have occurred frequently, seriously endangering the quality of animal food. Therefore, the issue of feed has become a hot topic of concern for the general public and has attracted the attention of relevant national departments. To ensure the quality of feed and feed additives, the National Regulations on the Administration of Feed and Feed Additives2012year5the moon1Formally implemented from [date].2012year10the moon9The Ministry of Agriculture of Japan has also reviewed and approved the "License Conditions for Feed Enterprises" and "License Conditions for Mixed Feed Additive Enterprises" in accordance with the regulations2012year12the moon1Implemented from [date].

The Regulation clearly stipulates that feed and feed additive enterprises have "necessary product quality inspection institutions, personnel, facilities, and quality management systems"; The "License Conditions" have put forward more clear requirements for product quality inspection. Enterprises * * have a feed testing laboratory and are equipped with effective liquid chromatography (equipped with ultraviolet detectors) or atomic absorption spectrophotometry (equipped with flame atomic spectrometers and element lamps for the tested items) or both according to their own feed types.

Our company has developed a comprehensive feed testing laboratory solution in accordance with national policies, which includes pre-sales consultation, equipment matching, testing method training, after-sales service, and * * standardized servicesThe results are accurate and reliable, with good detection limits, widely applicable for the determination of various vitamins in compound feed, concentrated feed, compound premix feed, and vitamin premix feed.It is one of the standard instruments for ensuring feed quality by successfully passing the certification system acceptance.

1、 Characteristics of effective liquid chromatography for vitamin detection in feed:

1The entire system adopts a modular structure design, with components such as infusion pumps and detectors freely matched, and strong scalability; All key components are imported with original packaging, making analysis more reliable and performance more stable.2The high-pressure infusion pump has a high pressure resistance of up to42MpaBy using electronic compensation, the flow pressure is more stable and the reproducibility is better.3The ultraviolet detector adopts a straight band optical method, with a simple structure, easy maintenance, fast self checking speed, high wavelength accuracy, and good reproducibility.

2、 Main technical parameters: 1Infusion method: Double plunger series pump2Flow rate range:0.001-9.999ml/min 3Work pressure:42Mpa 4Scope of testing:（190-700）mm,Single wavelength5Control: Panel control or workstation reverse control.
