Introduction of HPLC Liquid Chromatography Instrument:
HPLC is short for the High Performance Liquid Chromatography. HPLC is mainly for analysis of carbohydrates, vitamins, protein, aminoacid, additives, hormones, mycotoxins, pesticides residues, veterinarydrug residues, and inorganic components in food products to ensurefood safety. lt is also has a wide range of applications in the specificmigration in food contact materials.

Features of HPLC Liquid Chromatography Instrument:
High Pressure Constant Current Pump Features:
1. Small pressure pulsation: the new tandem cam design, integrated with the fifth generation of intelligent algorithms, through the "electronic pulsation suppression" control, reducing the pressure pulsation; further reducing the pressure fluctuations, to ensure that the test results of higher repeatability.
2. Acetonitrile Resistant Check Valve: Adopting a new type of check valve greatly reduces the possible failure of the check valve when pure acetonitrile is used in the system.
Vacuum Membrane Degassing System:
1. Built-in 5-channel vacuum pump, pressure sensor, real-time monitoring of vacuum cavity pressure changes, to ensure timely and efficient degassing operation.
2. Needle in the flow path: Needle in the flow path design, to meet the sample injection zero loss;
Heating and Cooling Column Chamber (CT3400)
1. Dual-mode heating: heating-cooling dual-mode temperature control. Standard with semiconductor cooling module, resistance heating module.
2. Air bath: forced air bath circulation temperature control.
3. Temperature setting range: 4℃-90℃;
4. Temperature control range: room temperature -10 ℃ ~ room temperature +70.0 ℃ (not exceeding the maximum temperature, standard refrigeration module)
SmartLab Software
