Name: Bulose Sihle Student Number: 209504496 Date of Practical: 11 April 2013 Inductively Coupled Plasma – Atomic Emission Spectroscopy Aim The aim of this practical was to use an ICP-OES to perform a multi-elemental analysis of different types of tea. The elements that were analysed in the tea were copper‚ iron‚ manganese and magnesium. The sample is introduced into the plasma as an aerosol. Argon gas flows through three concentric quartz tubes in the plasma torch. This argon gas transports

RESULTS AND DISCUSSION: Ultraviolet spectroscopy of Verapamil hydrochloride at λmax of 278 nm in pH 1.2 buffer was found to be linear in range of 20 – 80 µg/ ml. The method was validated and found to be precise‚ specific and accurate. The tablets of Verapamil hydrochloride were prepared by press coating technique showing sustained release for 24 h for once daily dosing with a lag phase of 4 - 6 h. The optimum ratios and type of polymers and other excipients were chosen to produce gastroretentive

POLYMER SYNTHESIS AND PROPERTIES AIM: The aim of the experiment was to prepare three different polymers‚ namely nylon 66‚ Agar Gel and slime‚ being able to differentiate between the configuration and analysis among the three structures‚ noting the physical characteristics of each polymer and the chemical reactions that occur during the formation of the polymer. Pre- lab questions 1. Is Nylon 66 a step or chain – growth polymer? Define both types of polymerization in your answer. Nylon 66

Isolation of Eugenol from Cloves by Steam Distillation and its Identification by Infrared Spectroscopy Eim A. Chemist CHEM 303 June 16‚ 2005 INTRODUCTION “Essential oils” are the volatile components associated with the aromas of many plants.1 In this experiment‚ the essential oil eugenol (the main component of oil of cloves) will be isolated from ground cloves using the technique of steam distillation‚ which is often used to isolate liquid natural products from plants.2 The principle

2.2.1.6 Inductively Coupled Plasma-Atomic Emission Spectroscopy Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) is one of several techniques available in analytical atomic spectroscopy. ICP-AES utilizes plasma as the atomization and excitation source. Plasma is an electrically neutral‚ highly ionized gas that consists of ions‚ electrons‚ and atoms. Most analytical plasmas operate with pure argon or helium‚ which makes combustion impossible. Plasmas are characterized by their temperature

Organic vs. Inorganic Le’Trice Crawford CRJ311: Forensics Christopher Mancuso May 18 ‚ 2012 The world that we live in is made up of organic and inorganic materials. The thing is known which is when you are confronted with a list of objects. This is the reason in this paper I intend to show the difference between organic and inorganic organisms. The definition of organic which means‚ of or pertaining to an organ; or the organs of an animal
