    favorite candies? Chromatography can solve that for you. Chromatography is a separation technique used by scientists for separating both organic and inorganic compounds. There are four different types of chromatography: thin layer‚ liquid‚ gas‚ and paper‚ but for this lab paper chromatography will be used. Who invented chromatography? A Russian botanist named Mikhail Semyonovich Tsvet invented chromatography in 1901 while doing research on plant pigments. Why is chromatography so important? This

    Plant Pigment Chromatography VII. Analysis (Questions) 1. What factors are involved in the separation of pigments? Factors that are involved in the separation of pigments can include pigment solubility‚ the attraction between the pigments and paper and the size of each pigment particle. Because of these factors the results were as they were. Beta-carotene traveled the furthest because it forms no hydrogen bonds to the chromatography paper and is slightly soluble in the solvent. Contrastingly

    Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

    Chromatography • • • Separation based on polarity of compounds Two potential phases for a compound to exist in: mobile and stationary Partitioning of compounds between mobile phase and stationary phase occurs: o Compounds that are less polar move more in the mobile phase‚ those that are more polar “stick” more on the stationary phase o These polarity differences cause compounds move at different rates and therefore can be separated 1. Mobile Phase: the phase the moves; can be gas or

    Gas chromatography (GC) is a chromatography technique where the separation of individual components (analytes) from a sample relies on their differing distribution between a mobile and stationary phase. The mobile phase carries the analytes through the stationary phase. In GC‚ it’s an inert gas (usually helium or nitrogen). The gas must be inert‚ so it won’t react with the sample to give a false reading. The stationary phase is a substance fixed in place to which the sample adsorbs because
