Flame Photometry 1) Principal of Flame Photometry: It is the conversion of molecules to their component atoms in gaseous state ; and it is carried out by introduction of the molecules solution in the flame in very fine droplet Atoms in gaseous state in the flame absorb thermal energy from the flame itself ,some of the atoms get excited & as they return back to the ground state they emit radiation having energy equal to that absorbed. The emission is proportional to the number of excited atoms, which

Chapter III Methodology 5.1 Study Design The study will utilize the Quasi experimental research, which describes and analyzes the variables that will be manipulated to influence an effect to the independent variable. Blood will be obtained from students of Medical Technology in Far Eastern University. The blood samples obtained from the student will be observed microscopically after adding the plant extract. Prothrombin time test will also be used to compare the time of coagulation between citrated

THIN LAYER CHROMATOGRAPHY (TLC) Thin Layer Chromatography is a simple, fast, multipurpose, sensitive, inexpensive analytical technique for the separation of substances. TLC has a mobile phase that is a liquid while the stationary phase is an active solid, known as the sorbent. Such sorbents are silica, cellulose, alumina, polyamides, ion-exchangers, and other numerous minor organic and inorganic sorbents. The considerable versatility of the sorbents depends on the type of substances being separated

mathematician and inventor. Babbage mentored Ada, and she soon began studying mathematics at the University of London. Babbage invented the difference engine, which was used to perform mathematical calculations. Babbage also created the analytical engine. The analytical engine was designed to handle more complex calculations. Luigi Federico Menabrea, an italian engineer, wrote an article over the analytic engine. Ada was asked to translate this article, and ended up adding her own thoughts and comments

of separating different coloured dyes(chromatography) and to relate this to real-world in society. Materials: 6 filter paper strips 3coloured felt-pens Pencil 250ml beaker Packet of "M and M's" 2 paddle pop stick 6 paper clips 3 matches Water Procedure: Step 1:On one end of a filter strip,wrote in pencil the brand name of colour of a felt-tip pen that was tested. Step 2: They used a felt-pen to draw a large dot about 1.5 from the other end of the filter paper strips. Step 3: It was repeated

Alice Walker the Woman and Jesus Name: Class: English 125 Date: October 1, 2012 Instructor: Alice Walker wrote a story about an old black woman whom wanted to attend church but was not able to be permitted to attend. My interpretation of what Alice Walker wrote about the old lady experience when she tried to attend a white church and was thrown out will shine a light on how strong this old lady was and give some cultural conflict to why this happen to her. Archetypal

element and water sample were determined using the method of linear calibration and standard addition method through atomic absorption spectroscopic. In instrumental technique, the proportionalities need to be practically established in calibration procedure. In a typical simple calibration, a range of standard is prepared containing varying amounts of the analyte. The standard additions method was used to determine the present of Zn which more effective to reduce the problems of matrix effects. The

(5 mm x 3.8 mm i.d.) were cryofocused at the head of a capillary column prior to a GC/MS analysis. The desorption temperature was set at a point about 20 degrees C higher than the melting point of each sample individually, and held for 3 min. The analytical results using 7 different pharmaceuticals were in agreement with those obtained by direct injection (DI) of the solution, followed by USP XXIII. This proposed TD-GC/MS method was demonstrated to be very useful for the identification and quantification

Estimation of optimal serum concentrations of 25-hydroxyvitamin D for multiple health outcomes1–3 Heike A Bischoff-Ferrari, Edward Giovannucci, Walter C Willett, Thomas Dietrich, and Bess Dawson-Hughes Downloaded from ajcn.nutrition.org at UNIVERSITY OF OTAGO SCIENCE LIBRARY on September 23, 2012 ABSTRACT Recent evidence suggests that vitamin D intakes above current recommendations may be associated with better health outcomes. However, optimal serum concentrations of 25-hydroxyvitamin D [25(OH)D]

Ass Analytical chemistry What is Qualitative Analysis? Qualitative analysis is the aspect of analytical chemistry dealing with the identification of elements or compounds in an unknown substance. Very simply put, it answers the question "What is in this sample?" and usually does so with yes/no question. What is Quantitative Analysis? Quantitative chemical analysis is the aspect of analytical chemistry dealing with determining the quantity of a particular chemical is in a substance. In short
