1/5/2012 · After mixing the sample solutions 1 min by using vortex, they were filtered through a 0.45 μm PTFE filter. Finally they were diluted to 1/25 proportion with acetonitrile–water (1:1, v/v). For the second and third slimming product, the same procedure was applied. 6 different capsules were weighted and mean value found 218.983 mg and 373.9 mg, respectively.
Membranes are available in either 0,2 or 0,45 µm pore size, with the choice often made on analytical column packing size. If the column packing size is larger than 3 μm then use 0,45 μm, and if 3 μm or smaller then use 0,2 μm. Suitable for HPLC: Low levels of UV-detectable extractables.
Before 0.2 and 0.22 micron filters became standard, it was thought that filters with an absolute rating of 0.45 micron were thought to be sufficient to strain out even the smallest bacteria. However, the discovery of Brevundimonas diminuta, showed that there were still bacteria capable of passing through a 0.45 micron filter in large quantities.

1/1/2011 · Then the sample was filtered through a 0.45 µm syringe filter (Millipore) and 50 µL of the solution was injected to the HPLC. Calibration curve was constructed in five spiked concentrations of OTC (0.1, 0.2, 0.5, 0.7, 1 µg/mL) and then, samples were injected into the HPLC system and peak area of OTC was plotted versus OTC concentration.
