Determination of citric acid in fruit juices using HPLC
An isocratic elution was carried out on a Varian ProStar HPLC system with a 50-mm × 4.6mm- Kinetex XB-C18 column (Phenomenex) with a 2.6-µm particle size and 100-Å pore size. The mobile phase was 100% 50-mM phosphate buffer at pH 2.80. The HPLC system operated at a flow rate of 0.5 mL/min, the injection volume was 5 µL, and the

Membrane Filtration: Choosing the Correct Type of Filter | Cytiva
Ensuring the correct filtration membrane has been selected from different types of filter materials is often overlooked in routine laboratory sample filtration. Here, we explore different filtration properties and how to take a preventative—rather than reactive—approach, minimizing time spent troubleshooting and maximizing efficiency.
Whatman® membrane filters PTFE pore size 0.2 μm, diam. 47 mm
PTFE membranes are particularly suitable for preparing samples for HPLC analysis. The hydrophobic nature of the membrane also has applications for air and gas sterilization. The membrane is laminated onto a nonwoven polypropylene support web for improved strength and handling and can be used at temperatures up to 120ºC.
