Experiment 5 Analysis of Plant Pigment Purpose: Chromatography is used for separation. In this case the separation of plant pigments. After placing the plant sample in the column the separation will be easy to see and the samples will be analyzed using VIS spectrophotometry. This is used to isolate and identify the different lipids causing the different pigmentations. Introduction: Lipids are chemically diverse substances found in cells. Lipids are water-insoluble‚ structural components

composition that was found out in the analysis. The % composition of the yield was found out by using the % composition of the products and a gas chromatography by measuring the peak areas for each gas chromatogram. The operations used in this lab in their order of usage were: Simple distillation‚ mixing‚ washing liquids‚ drying liquids‚ gas chromatography. 2. Procedure The volume of 20 mmol of 2-methylcyclohexanol was calculated and transferred into a round-bottom flask. Then 0.7 mL of 85 % phosphoric

Caffeine is a drug that is used to improve mental alertness by stimulating the central nervous system [1]. It is an ingredient found in a various amount of products sold on the market today‚ such as coffee‚ tea‚ chocolate‚ soft drinks‚ and energy drinks. Caffeine can be taken by mouth or intravenously (by IV) to help alleviate breathing problems in infants and can even be used in combination with some pain killers to treat migraines after epidural anesthesia. Moreover‚ it can be helpful in preventing

Introduction Chromatography is a technique used to separate a mixture into its individual components. In this experiment‚ chromatography is done by using a thin layer chromatography (TLC) plate and filter paper. The word ‘chromatography’ itself means the separation of colours. However‚ nowadays‚ both coloured and colourless compound are used in chromatography by various methods. In chromatography‚ the separation process of mixture is mainly based upon the polarity and molecular weight of sample

HPLC Theory: System Suitability Parameters High performance liquid chromatography is defined as a separation of mixtures of compounds due to differences in their distribution equilibrium between two phases‚ the stationary phase packed inside columns and the mobile phase‚ delivered through the columns by high pressure pumps. Components whose distribution into the stationary phase is higher‚ are retained longer‚ and get separated from those with lower distribution into the stationary phase. The

Tamilnadu. E-Mail: velmpharm24@gmail.com A precise‚ accurate and rapid RP-HPLC method has been developed and validated for the simultaneous estimation of Tamsulosin Hydrochloride and Finasteride in tablet dosage form. Chromatography was carried on RP – 18e Hiber RT (250 × 4.6) column using Water:Methanol (30:70%) v/v as mobile phase at a flow rate 0.7 ml/min and the effluent was monitored at 225 nm. The retention times of Tamsulosin Hydrochloride and Finasteride were 5.4
