High quality filtration products that are easy to use, reliable, and consistent with reproducible results each and every time, are required in pharmaceutical HPLC sample preparation.
Pharmaceutical R&D widely uses liquid chromatography in QC operations. Thomson offers an eco-friendly solution with a considerable cost savings advantage in the Filter Vial (patented). Analyzing pharmaceutical tablets and capsules for dissolution and content uniformity could not be easier and safer than with the Thomson Filter Vial. Filtration being the final step before analysis by HPLC or another procedure, Thomson offers a wide range of membranes PTFE, PVDF, Nylon, and PES in sizes of .2μm and .45μm.
Thomson has a solid technical library covering many protocols for HPLC sample preparation. In our experience HPLC sample preparation for protein precipitation is best done with Thomson's PVDF .2μm Filter Vial. The Thomson PES .2μm Filter Vial performed best in HPLC sample preparation for antibody analysis. If you are looking for an accurate way for real time quantification for biofermentation by HPLC or LC/MS, you should really try Thomson's PVDF .2μm Filter Vial. Of course, you might wish to try another membrane for your specific fermentation. When you would like to speed up your sample precipitation for TLC plates you can use the Thomson PTFE .45μm Filter Vial.
