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.
Apart from the basic column characteristics discussed in previous module stationary phase choice is a critical decision for achieving the right analytical conditions. Stationary phases are required for both Gas Solid Chromatography (GSC) and Gas Liquid Chromatography (GLC). Gas Solid Chromatography separates components in the carrier gas stream by selective adsorption on solid stationary phase whereas in GLC the components are bound to the liquid layer adsorbed on the solid support. GLC Solid Supports. Used for separation of permanent gases and highly volatile organic compounds.
