2019-3-29 · First wash your column with 100% water as most of the buffer have greater solubility in water. After washing with water, gradually increase the flow rate upto 2ml with 50%ACN upto 4hours and then store the column as per column guide. Check your gradient programm as mixing of buffer and ACN may lead to high column pressure.

2019-6-19 · The problem is that after the wash, some people finish with 10–15 column volumes of 5:95 water–acetonitrile. It seems that this last step is really bad for the column. We know that the ion-pairing reagents are never really completely removed from the column after the wash, so we dedicate the column for ion pairing use only.
2015-12-16 · The froth of a flotation column is usually . water washed, with approximately as much wash water as there is water reporting to the froth. The water is most commonly added via pans, perforated with 4-8 mm diameter holes, located 20-30 cm above the froth, thus generating a “rain” of water onto the surface of the froth.
A column can support a deep froth bed and may use wash water to maintain a downward flow of water (positive bias) evenly across the cross-section of the vessel. This essentially eliminates the entrainment of hydrophilic particles in the float product when the vessel is used for solid/solid separation.

2017-2-14 · Practical limits of column stability require that we truncate the lower range to 2.0 pH 3.1 and eliminate the highest range. Notice that there is a gap in buffering between pH 3.1 and pH 6.2 for phosphate. This means that, although it is possible to adjust the pH of phosphate to 5.0, there is negligible buffering capacity at this pH.
