Instruments: UV/VIS spectroscopy was used to analyze the absorption spectra of the many solutions in this experiment. It was chosen for its ability to collect absorption data quickly and efficiently. A Target Factor Analysis program was used to treat the UV/VIS data collected. Target Factor Analysis was used as the calculation method instead of CLSR due to it taking into account the interference2. Discussion: Table 1 is the calibration matrix

In 1860‚ the first instrumental analysis was performed by Robert Bunsen and Gustav Kirchoff who used flames tests that led to the discovery of the elements rubidium (Rb) and caesium (Cs). After this‚ this method was used everywhere to find the chemical make ups of many substances. For example‚ in 2007 there was a huge problem where tainted pet food would cause many pets to become ill. Qualitative analysis was used and it was discovered that Melamine was found in the pet food which altered the results

Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion
