About This Product
The system separates liquid samples by HPLC, with the quaternary pump blending up to 4 solvents at low pressure and the binary pump forming high-pressure gradients. Because the column compartment both cools and heats, separations can be run at a controlled temperature. Detection can be by UV/Vis at two wavelengths, by a 1024-channel photodiode array, or by refractive index.
Frequently Asked Questions
What wavelength range do the detectors cover?
The UV/Vis detector covers 190 to 900 nm with dual-wavelength operation, and the 1024-channel PDA detector covers 190 to 950 nm. The RI detector reads 1.00 to 1.75 RIU.
How many columns fit in the column compartment?
Up to 3 analytical or 2 semi-prep columns of 30 cm length. The compartment runs from 4 degrees C with cooling up to 90 degrees C.
What is the difference between the two pumps?
The quaternary pump uses parallel dual plungers with a low-pressure gradient from a 4-channel mixing valve for up to 4 solvents. The binary pump uses double parallel dual plungers to form a high-pressure gradient.
