To further validate the device, the authors completed 12 analyses at each of three known concentrations of glucose and protein, obtaining acceptable accuracy and precision in all cases. What is possible in a developed country, such as the United States, may not be feasible in a country with fewer resources because lab equipment is expensive, and because there may be a shortage of trained personnel to run the tests and to interpret the results. Analytical chemistry, however, is much more than a collection of analytical methods and an understanding of equilibrium chemistry; it is an approach to solving chemical problems. An Inquiry-Based Analytical Chemistry Course. In summary, the authors report the successful development of an inexpensive, portable, and easy-to-use device for running clinical samples in developing countries.

In some cases the result of the analysis is available in 10-15 minutes. For years, Dr. Pacey has used the “just in time” principle of parceling information and supplies to students in his analytical chemistry course. Solution: We know that there is a relation between atm and cm Hg; 1 atm = 76 cm Hg =760 mm Hg 760 mm Hg is 1 atm 570 Determination % Aspirin 1 91.30 2 91.25 3 91.20 4 91.31 5 91.26 You will find the article on pages 1574-1581 in Volume 80 of Analytical Chemistry, published in 2008. Anal. Digital pictures of the microfluidic device are taken with a cell phone camera and sent to an off-site physician who analyzes the picture using image editing software and interprets the assay’s result. In developing this analytical method the authors considered several chemical or physical interferences. chapter 03: second law of thermodynamics.

Airport security needs a more reliable method for detecting the presence of explosive materials in luggage. Gases Exam2 and Problem Solutions 1. In considering solutions to this problem, the authors identify seven important criteria for the device: it must be inexpensive; it must operate without the need for much electricity, so that it can be taken to remote sites; it must be adaptable to many types of assays; its operation must not require a highly skilled technician; it must be quantitative; it must be accurate; and it must produce results rapidly.
