Column 18 in chromatography typically refers to a specific type of stationary phase, often designed for reversed-phase chromatography. This column is favored for its ability to separate compounds based on hydrophobic interactions, making it ideal for analyzing non-polar and moderately polar compounds. The use of Column 18 enhances resolution and sensitivity, which is crucial for achieving accurate results in complex mixtures. Additionally, its broad applicability across various sample types makes it a popular choice in analytical labs.

What is a column of elements called in a periodic table?
A column is known as a group in periodic table. There are 18 groups in the modern setting of periodic table. Elements in the same group usually share same chemical properties and striking physical characteristic trends.
What column is the noble gases in?
The noble gases are found in column 18 (VIII Group) of the periodic table. This group includes elements such as helium, neon, argon, krypton, xenon, and radon. These elements are characterized by their stable electron configurations and lack of reactivity.

What column is helium neon and argon in?
Helium and neon are in the same group, Group 18 (Noble Gases), also known as Group 8A. Argon is also in Group 18.
What periodic trends exist for electrongavity?
Electronegativity increases from left to right across a period from column 1 through column 17 but drops sharply from column 17 to column 18.

The noble gases in Column 18 are called helium, neon, argon, krypton, xenon, and radon.
What is the square footage of a 12 foot round column with a radius of 18 inches?
18 sf
The noble gasses are found in column?
The noble gasses are found in the right-most column (group 18) on the period table.
What family on the periodic table contains elements that are mostly nonreactive?
Column 18, or in older tables, column VIII, the noble gases.
How much dmso should be used for a c-18 hplc column to knock out everything retained in the column?
Depends on the column..... For a regular C18, try running 10% methanol through and then full-loop injections of 50% DMSO repeatedly until you're happy with the result. Also, reduce the run-time. For me, 3 minutes for a 2x50mm.
Each column in the periodic table is called what?
A group, there ae 18 of them.
