COLUMN AND THIN LAYER CHROMATOGRAPHY Group 9 RAMOS‚ Sharina Joy; REYES Aina Marie; REYES Jallisa Maan; RUBIO‚ John Michael; SABINO Patricia Anne; SANTOS‚ Carlos Rafael ABSTRACT To separate the colored components of siling labuyo and to determine the purity of the components‚ the students performed a column and thin or solid-liquid chromatography procedure. The solid may be almost any material that does not dissolve in liquid phase. But for this experiment‚ the solid used by the students was

Thin-Layer Chromatography of Analgesics Abstract: In this experiment thin-layer chromatography (TLC) was used to determine the composition of an unknown mixture of analgesics given five references of AC‚ ASP‚ CAF‚ IBU‚ SAL‚ an unknown consisting of a mixture of three of the references‚ and two unknowns (6‚23) containing a single reference compound. The composition of the unknown mixture and two single unknowns were determined by spotting the reference compounds and the unknown compounds on two

Thin Layer Chromatography of the Unknown Analgesic Jessica Bajao*‚ Phoebe Abalos‚ Kevin Antiga‚ Carmelus Aseneta 3-Biology 2 College of Science‚ University of Santo Tomas‚ Manila‚ Philippines Abstract The group used five different analgesics in this experiment: aspirin‚ acetaminophen‚ ibuprofen‚ caffeine‚ and mefenamic acid. Six analgesics were spotted on the TLC plate including the unknown. After the development of the TLC plate‚ it was placed under ultraviolet light for the spots resulted

Expt. 8.1 Thin Layer Chromatography (TLC) Analysis of Analgesics Krista Jinks CH 211L Section F 10/27/14 I. Abstract: The objective of this experiment was to analyze analgesic tablets by TLC to determine what analgesics they contain. The analgesics that could be in the tablets included ibuprofen‚ acetaminophen‚ aspirin‚ and caffeine. Through the use of TLC‚ unknown substance #62 was found to be Bayer Aspirin because it only contained aspirin. II. Introduction: 1. Briefly describe

Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

Usually an aqueous and organic phase are used. During extraction the desired compound moves one phase and leaves the unwanted substance behind. Extraction normally has to be done a few times to leave all of the impurities

Drugs screen using Thin Layer Chromatography of basic illicit drugs Abstract The majority of evidence submitted to crime labs comes from drug-related crimes. Often‚ this evidence includes unidentified powders that may be illegal drugs. In order to prosecute individuals for possession of illegal substances‚ it is necessary for forensic scientists to positively identify any suspected drugs submitted to the laboratory. In addition‚ forensic toxicologists must determine the identity
