Proximity analysis is used by scientists to determine the amounts of substances in materials like animal feed, coal, and biofuels. The process involves obtaining a sample and analyzing it using extraction or remote sensing techniques. The goal is to determine if the material contains hazardous substances and if it meets quality control standards for human and animal consumption.
Proximity analysis is a type of scientific investigation performed to determine the approximate amounts of substances within a material. This is used by different types of scientists to study things like animal feed, coal, and biofuels. The process of proximity analysis is complicated and often involves remote mining or sensing to determine the varying amount of substances within a material, although different methods are used for different materials. This information can be used to build quality controls for various materials, ensure they do not contain any hazardous chemicals, and determine if they are healthy enough to be consumed by humans or animals.
The scientist begins the proximal analysis by obtaining a sample of the ready-to-use material. Sample size and methods of preparation vary according to the type of material being analyzed. Once the material has been prepared, the sample is analyzed using one of a few recognized techniques. Extraction is a means of using additional substances and chemicals to extract certain substances from the material so that they can be examined and measured. Remote sensing uses machines and robots to examine the material and estimate what it is made of.
After the sample has been analyzed using one of these techniques, a component analysis can be performed. The analysis is performed using both qualitative and quantitative techniques to form measurements and provide scientists with answers to their questions. The precise tools used for the analysis depend on the sample tested and the scientists’ goals in the experiment.
One of the main objectives of proximity analysis is to determine if there are any hazardous substances in a material sample. In industries like petroleum and coal, this can determine whether the item is safe to use in vehicles or burned, respectively. Environmental regulations require this information to be tested to ensure that hazardous fumes do not enter the atmosphere beyond a certain predetermined level. Materials must contain certain substances in order to pass quality control standards which are heavily regulated in most countries.
Another important use of proximity analysis is to find out if foods are safe for human and animal consumption. For livestock, feed is tested to ensure it contains enough protein, fat and carbohydrates for healthy animals. In human food, nutrient levels are tested to determine the levels of each within the product, as well as proteins, fats and carbohydrates.
