What is the difference between ods and bds column

However, this free silanol can cause errors during the analysis, so we have to cap these groups with some other compounds such as TMS trimethylsilyl groups, which are not bulky but highly reactive. This process is called end-capping. Hypersil and inertsil columns are trade names, and these are important reverse-phase HPLC columns.

The below infographic summarizes the differences between hypersil and inertsil column in tabular form. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry.

High Performance Liquid Chromatography system HPLC refers to a technique in analytical chemistry that is used to identify, separate and quantify each component in a mixture.

C8 and C18 both refer to the alkyl chain of a bonded face of a column. They are both used in the high performance liquid chromatography system. The two columns have some similarities, but they are also different in some way. Some of the differences between C18 and C8 are discussed here. This stationary phase works well for the retention of most organic analytes.

The mobile phase of the reverse phase HPLC is polar. There are different types of columns that are used for this chromatographic technique. Overview and Key Difference 2.

What is ODS Column 3. What is BDS Column 4. It is also abbreviated as C18 column because it contains octadecasilane chains. The value of pH for a weak acid is less than 7 and not neutral 7. Its pH value is less than that of strong acids. The pH scale describes how many hydrogen ions protons are present in a solution. The pH scale typically stretches from zero to 14, passing through a neutral pH7 freshly distilled water. But the scale does not have fixed limits, so it is indeed possible to have a pH above 14 or below zero.

Although the pH of blood ranges from 7. If the pH levels drop below 6. The pH is not more than 14 because it was fixed value established by the scientists and another reason is that no one acid and base can have the pH more than
