Main features
 
QGM Low Pressure Quaternary Gradient Pump: SFC system cosolvent delivery pump, pumping flow rate up to 150 mL/min.
 
P200X CO2 Pump: This is a high pressure delivery pump with a stainless steel twin head with cam-driven sapphire piston assembly, self-filling check valve, pressure sensor, pressure gauge, brushless motor and explosion-proof plate assembly. This pump has a unique design and can be automatically controlled according to the feedback of pressure sensor and mass flowmeter.
 
Modifier flow injector: This device satisfies the customer's need to inject modifier flow "only". Its function is to inject one sample at a time using a 2 mL standard Loop ring and a 5 mL syringe. With this device, the user can set air gaps before and after the sample, and the air gaps can be used as a "buffer" between the solvent and the sample, thus reducing the dilution degree. 
 
2767 Sample Manager: Open bed module for sample injection and fraction collection. The system provides the 2767 sample manager with a fume hood kit for managing CO2. Customers need to order sample injection and collection pipe racks for the system, and the applicable pipe racks are determined according to the specific needs of users.
