INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

Absorption costing: * It is costing system which treats all manufacturing costs including both the fixed and variable costs as product costs * In absorption costing‚ all costs are absorbed into production and thus operating statements do not distinguish between fixed and variable costs. * Absorption costing is a process of tracing the variable costs of production and the fixed costs of production to the product. Absorption costing is used to cost products and to report financial

Introduction In order to determine the content of calcium and magnesium in an unknown sample of limestone‚ the utilization of atomic absorption spectrophotometry can help in deciphering the unknown concentrations of each molecule in the limestone sample. Atomic absorption spectrophotometry‚ emits radiation of the correct frequency that is passed through a flame and the intensity of the transmitted radiation is measured¹.The calcium concentration or ppm can be measured using the absorbance of the

Absorption Costing Absorption costing is a method of costing that assigns a small percentage of production and overheads costs to the price of each product that is going to be sold. It accounts for all costs‚ direct and indirect‚ fixed and variable. For example; if 1000 products are made and the total costs are £10000 then each product would cost £10 before making a profit (10000/1000=10). Variable costs are costs that can be controlled by management or a sales worker. Whereas fixed costs are

Introduction At any particular wavelength the absorption of light when visible light passes through a solution depends on two factors: * The length of the light path * The concentration of the colored path The connection of these two variables is known as the Beer-Lambert Law: Absorbance (A) = ε c l Where ε is the absorption coefficient C is the concentration of the compound And l is the length of light usually 1cm When I is constant‚ this proves a linear relationship between

Dissolution[edit] In the most common situation‚ a tablet is ingested and passes through the esophagus to the stomach. The rate of dissolution is a key target for controlling the duration of a drug’s effect‚ and as such‚ several dosage forms that contain the same active ingredient may be available‚ differing only in the rate of dissolution. If a drug is supplied in a form that is not readily dissolved‚ the drug may be released more gradually over time with a longer duration of action. Having a

Absorption Costing vs. Variable (Direct) Costing Absorption cost systems are widely used to prepare financial accounts. These systems are designed to absorb all production costs (variable or fixed) into costs of units produced. Absorption costs techniques allow manufacturing costs to be traced and allocated into product costs. There are different types of absorption costing systems: job order costing‚ process costing‚ and ABC costing. In job order costing‚ costs are assigned to products in batches
