Why need for filtration
Sample and mobile phase filtration are simple, economical practices to extend the life of chromatography consumable. A basic HPLC system consists of solvent reservoir, pump,injector, column, detector, and data recording system. Particles and microbial not removed by filtration interfere with nearly every system component.
Mobile phase filtration
Mobile phase filtration can reduce the possibility of sieve blockage, accessories pollution, valve damage, capillary occlusion, peak distortion, and the occurrence of interfering peaks and baseline noise.
Columns
Significant problems with HPLC columns are chemical absorption, blocked frits and channel voids. Chemical changes are prevented with guard columns. Voids are created by particulate matter and pressure shock. If poor peak shapes become evident by badly tailing and splitting, without a change in retention time, blocked frits or a column void has occurred.
Daily maintenances commented to protect columns and whole system include:
1.Filtering solvents through filter membrane.
2.Filtering samples through syringe filter.
3.Utilizing a 0.5 μm in-line filter to trap injector and pump particulates.
Product Introduction
Polyethersulfone(PES)
Hydrophilic membranes, high flow rate and high throughputs, low protein binding, low in extractables, and can be used to remove small particles, bacteria, viruses and fungi from aqueous phase. Normally used with pH range 3-12.
Nylon
Excellent chemical stability and flexibility, durable, hard to tear, can be sterilized in 121 o C. Suitable for filtration of aqueous and most organic solvents, such as the water filtration of electronic, microelectronic, semiconductor industry, and also the filtration of culture media, drugs, drinks, and high-purity chemical. Normally used with pH range 3-14.
Hydrophobic Polytetrafluoroethylene (PTFE)
Broad solvent chemical compatibility, excellent particle retention, and compatibility with various sterilizing methods. Suitable for both liquid and gas filtration. Normally used with pH range 1-14.
Hydrophilic Polytetrafluoroethylene (PTFE)
Broad chemical resistance, excellent particle retention, and compatibility with various sterilizing methods. Suitable for the filtration of aggressive organic solvents, water solution containing strong acids or alkalis, and mixed solution of both. Normally used with pH range 1-14.
Hydrophobic Polyvinylidene fluoride (PVDF)
High mechanical and tensile strength, and have broad chemical and temperature resistance. Not suitable for the filtration of acetone, DMSO, THF, etc. suitable for the filtration of gas, steam and high temperature liquids. Normally used with pH range 2-13.
Hydrophilic Polyvinylidene fluoride (PVDF)
Low protein binding, and have broad chemical and temperature resistance. The chemical compatibility of the membrane includes aggressive acids and alcohols. We do not recommend using this membrane for the filtration of acetone, DMSO, or bases > 6N. The filtration of dilute protein samples is recommended. Normally used with pH range 2-13.
Cellulose Acetate (CA/CN)
Membranes exhibit ultra-low protein binding and are broadly used in the filtration of biological samples. This membrane is excellent for filtration of tissue culture media, general biological sample filtration and clarification.
Glass Fiber (GF)
Made of inert borosilicate glass and have a nominal 1.2µm pore size. They are commonly used with highly viscous samples or samples containing high concentrations of particulate matter (e.g., food analysis, biological samples, soil samples, fermentation broth samples, removal of yeasts, molds, etc.).
