Pore Size (0.2 and 0.45 µm) — The filter pore size is usually a personal preference of the chromatographer but relates to the column packing material. Since there are many different packing materials, a general guideline is that most customers find that the 0.45 µm filter meets their requirements, although chromatographers are increasingly moving toward using 0.2 µm filters.
The diluted syrups and the supernatants of the tablet extracts were filtered by a 0.2-μm nylon syringe filter (Thermo Scientific) before HPLC analysis. Each stock standard solution of chlorogenic acid (1.47 mg/mL), nicotiflorin (0.35 mg/mL), hederacoside C (9.835 mg/mL) and hederasaponin B (0.3985 mg/mL) was prepared in 50% methanol.
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
