It is the amount a business charges above their direct cost. If your contractor has a 1.50 markup (which is reasonable for a remodeling contractor), that means that if the estimated cost for a job is $10,000, they'll multiply the $10,000 x 1.50 and arrive at a $15,000 sales price.ow many people who know little about business and even less about the costs of running a business will say, Oh, look at that crook. He is making $5,000 profit on my job.. Nope, not true.
Partition chromatography is often preferred for the latter, wherein an inert solid (often silica gel) is coated with a liquid phase. Hydrophobic interaction chromatography (HIC) is a special form of surface adsorption chromatography. The materials to be separated should be at least partially hydrophobic in nature.
Difference between Spectroscopy & Chromatography. Spectroscopy is the study of the interaction between matter and electromagnetic radiation. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. Later the concept was expanded greatly to include any interaction with radiative energy as a function of its wavelength or frequency.
