Food composition analysis is to analyze the biological materials in the natural food and organic components - carbohydrates, proteins and amino acids, lipids and fatty acids, organic acids, nucleic acids and nucleotides, vitamins, hormones, food toxins, and food processing to add artificial coloring agents, flavoring agents, anti-microbial agents, olfactory sense of the material and the determination of other food additives. From the analysis of the food products into the human body human benefit. The food composition of what equipment? Jie Nanjing Section necessary professionals will provide you with a variety of food composition analysis equipment program. Equipment needed for the analysis of food ingredients can also be used by gas chromatography liquid chromatography, specific conditions. The following details of the instruments Co., Ltd. Nanjing Branch McNair provided for everyone GC5890F gas chromatography and liquid chromatography, LC-600.

 3, the food composition analysis chromatography workstation: 
 LC-WS600 chromatography workstation has a dual function: the control LC-600 liquid chromatography systems and chromatography data processing. 
 Control functions: the adoption and LC-UV600 UV detector between the RS232 communication cable, in the graphical interface can also control up to four of the LC-P600 constant high pressure pump and LC-UV600 UV detector, pressure to achieve multiple gradient elution and wavelength scanning functions. Can display the pump flow, pressure, analysis, time curves and wavelength scanning curve. Chromatography data processing: accept LC-UV600 UV detector digital signal sent directly for processing. 

 Second, the food composition analysis by gas chromatography; 
 1. Product Specifications: GC5890F 
 2. Main configuration: Dual FID, capillary injection system, the packed column inlet system, third-order process heating, smart devices after the door
