Experiment 5 Analysis of Analgesic Tablet by High Performance Liquid Chromatography Abstract An unknown sample‚ 529‚ was tested using high performance liquid chromatography to detect the concentrations of acetaminophen‚ aspirin‚ and caffeine respectively. There was found to be 4.03±0.144mg/100mL of acetaminophen‚ 11.5±0.185mg/100mL of aspirin‚ and 4.89±0.185mg/100mL of caffeine. Based on accepted values‚ the maximum daily amounts of each compound are 4000mg of acetaminophen

2-15-11 Purpose: The purpose of this experiment was to take spinach leaves and extract the chlorophyll and carotenoid pigments by using acetone as the solvent. The chlorophyll and carotenoid pigments were extracted by using column chromography and alumina was used as the solvent. Solvents of different polarities were used‚ starting with the least polar‚ to extract the certain components from the leaves. They were then analyzed by using thin- layer chromatography. Procedure: The first part

ETHNOMEDICAL SURVEY This survey was conducted in a Malay village name kampong Tanjung Sabtu located at West Kuala Terengganu‚ the capital city of Terengganu in Peninsular Malaysia. Most the villagers are farmers and some government staffs. This data obtain from the conversation adult villager‚ local healer and herbalist by using the ethnomedical enquiries. Mostly the villagers willing to share their knowledge on the uses of some medicinal plants. Total 52 plants were recorded to be used among

evaporating gels to make a hand wipe that visitors to hospitals can use. Also disinfecting is "de-natured" or industrial alcohol‚ which is a mixture of ethanol with 10% methanol‚ and almost no water. The industrial type is stained purple‚ and includes a foul tasting disinfectant emetic to discourage drinking it (because methanol is toxic causing blindness‚ insanity and death). The lab type is clear‚ smells of vodka‚ and is just as toxic! It will sterilize medical equipment. Source(s): http://wiki

from the petri dish or tube. Harvest just enough culture. (only use a tiny amount of culture preparing a smear) Spread the bacteria on the glass slide. Set the slide to air dry. Either heat fix or methanol fix. (do not fix it both ways) Stain the slides. Properly dispose of any wastes.(waste methanol‚ materials contaminated with bacteria‚ broken glass) Part II.

RENEWABLE ENERGY RESOURCES ABSTRACT The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels (i.e.‚ coal‚ petroleum and natural gas) and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy
