HPLC-UV Test of Extractable Species for Empty Flash PP Cartridge and PE Frit

Experiment Purpose:

Flash column are commonly used in lab separation of mixture species, the most import properties for the flash column are separation efficiency and low extraction blank level, this experiment is aimed to confirm that Hawach empty flash PP Cartridge and PE frit have no extractable species which could be tested by HPLC-UV.

Experiment Process:

Fill the empty flash column with 6 ml HPLC grade methanol, methanol/dichloromethane(3:1) mixture solution, and petroleum ether/ethyl acetate(1:1) separately for 24 h, and then test the extraction solvents by HPLC-UV.

HPLC-UV Parameters

Column : C18:250*4.6 mm
Flow rate: 1mL/min
Wavelength: 220 nm
Injection Volume: 20 μL
Temperature: 40°C
Analysis Time: 45 min
Mobile Phases: A) Acetonitrile B) Water

Gradient:

Hold 60% A for 10 min
60% to 95% A in 20 min
95% to 100% A in 10 min

Experiment Results:

As shown in the figure below, we can see that all the curve of extraction solvents has the same shape with that of the blank solvents, and there is no other peaks appeared, meaning that no extractable impurities of Hawach flash column.
