Microwave acid dissolution of soil samples for elemental analysis

Microwave acid sample decomposition for elemental analysis

resistant version of the standard Zymark arm was chosen for this project. A special problem was posed, however, in the handling of these solutions in the volumes required (10-300 mL) without contaminating the delivery devices. A solution was found through the use of peristaltic pumps and three-way pinch valves. These components were assembled into a pump station controlled by digital signals fr...

Elemental Analysis of Biological and Cryogenic Samples

Introduction Commercial production of large-area silicon drift detectors (SDDs) heralds an exciting new time in biological elemental analysis. Improved low-energy performance and higher collection efficiencies mean EDS is no longer limited by low count rates and poor solid angles. High count rates can be achieved on all types of materials, including soft biological tissues, without altering nor...

analysis of ruin probability for insurance companies using markov chain

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...

Monte Carlo Simulations for Non-destructive Elemental Analysis of Large Samples by Neutron Activation Analysis

Neutron Activation Analysis (NAA) is an established nuclear analytical technique with applications in a broad range of scientific and technological fields. Typically, conventional NAA involves analysis of small material portions of 10 to 100 g in mass. However, analysis of samples of a larger mass implies a number of additional advantages such as (a) analysis of objects too precious to remove ...
