• Development of A Filter Cake Permeability Test Methodology (.pdf)
  Permeability is an important characteristic of filter aid products. It can be tested by the liquid flowing through already formed cake approach (Method I) or by the cake filtration approach (Method II). Although in method I permeability is easily calculated, two test runs are required. This method...
• Quality Test of Rice Hull Ash Filter Aids (.pdf)
  of solid-liquid suspensions with filter aids as a body feed. Standard methods of testing filter aids quality include pH, particle size, bulk density, permeability, solid rejection rate, and moisture of cake. Test results of different grades of RHA filter aids are presented. Microsoft Word - Quality Test...
• Oxygen in living color
  Food Technology Centre (GFTC), Guelph, Ont., has several advantages over conventional testing methods says GFTC Senior Research Scientist Carol Zweep. It can provide a means to accurately predict the oxidative shelf life of a liquid-based product. This can save valuable time that would be required...
• Evaluating Thin-cake Pressure Filtration Using the BHS Autopress Technology
  Solid-liquid separation and cake washing are integral steps in the production of bulk or final pharmaceutical products. Each step must be optimized, along with the downstream dryer. Complicating this process is the number of competing technologies and options that can be employed to accomplish...
• Critical Leak Requirements in GC/MS, LC/MS and Analytical Instruments (.pdf)
  Gas Chromatography/Mass Spectrometry (GC/MS) and Liquid Chromatography/Mass Spectrometry (LC/MS) are analytical techniques used for chemical analysis. The properties of a sample are first separated using chromatography and then identified with the mass spectrometer. The equipment used...

  and very reliable with. liquid and dry formulations. With their robust design, they enable testing and analysis to be performed in the field. without being affected by dust or vibration, and provide reliable analysis even under. adverse industrial conditions for routine analysis. From this information...
• Customized Filter Material Supports Innovation In The Medical Industry
  its function and the environment it must endure. The filter's function determines the filter material's flow rate and permeability. In the case of this particular filter, pore sizes must range from 0.2 to 0.22 microns for sterile liquid filtration (also a common size for use with antibiotic solutions...
