The current invention provides compositions, which are useful as stationary phases for a variety of chromatographic applications, such as high performance liquid chromatography (HPLC). The compositions include a substrate (e.g., silica gel), covalently bound to a compound, which includes both a hydr...
Explain the necessary similarities and/or differences between the components of a mixture in order for recrystallization to be used as an effective method for the separation of two organic compounds. In other words, how must Compound S and Compound T be ...
The determination of constituents of rocks and minerals by gas chromatography. Part II. The determination of some gaseous constituents Chromatographic columns containing the appropriate stationary phase and a thermal conductivity cell have been used for separating and detecting these components. Gases that ...

In mass spectrometry,...Terence Hetzel...
rotation of solute bonds, the solute structure can undergo changes enabling better location on or in the stationary phase; descriptor values calculated for the presumed new 3D structures and used in regression calculations might give a better fit between the experimental and calculated retention values...

The trace analysis of solvents in dilute solutions by capillary gas chromatography (GC) is often difficult because of partial solvent trapping effects. The problems of solvent effects with such samples are shown by the example of chloroform. Two solvent effects, solvent trapping and phase soaking, ...
The capacity of the retention gap for dirt increases with increasing film thickness of the stationary phase in the coated column. A column coated with a very thin (0.06 渭m) film of an apolar stationary phase, with a retention gap, tolerated about 1 渭g of triglycerides without broadening ...
Bacteria produce the significant expression of virulence factors in the stationary phase [12,13]. Stationary phase cells are physiologically comparable to biofilm bacteria [7]. One key shift is the development of persister cells and small colony variants formed during the stationary phase, in biofilm...
