The "ultimate" analysis" gives the composition of the biomass in wt% of carbon, hydrogen and oxygen (the major components) as well as sulfur and nitrogen (if any). The carbon determination includes that present in the organic coal substance and any originally present as mineral carbonate. The hydrogen determination includes that in the organic materials in coal and in all water associated with the coal. All nitrogen determined is assumed to be part of the organic materials in coal.
The "proximate" analysis gives moisture content, volatile content,consisting of gases and vapors driven off during pyrolysis (when heated to 950 C), the fixed carbon and the ash,the inorganic residue remaining after combustion in the sample and the high heating value (HHV) based on the complete combustion of the sample to carbon dioxide and liquid water. Proximate analysis is the most often used analysis for characterizing coals in connection with their utilization.
how to convert proximate analysis of coal to ultimate analysis
practically there is no difference ..bt theoretically it has ...... ultimate analysis leads to the total summation while the proximate leads to the avg value .....

proximate analysis of fat can be done by using soxhlet apparatus
Carbon84 - 87%Hydrogen11 - 14%Sulphur0 - 6%Nitrogen0 - 1%Oxygen0 - 2%
It is proximate.

Proximate analysis is important because it is one of the most effective ways to analyze nutritional value and energy value in food.
We do proximate analysis of the matter to know the nitrogen (protein), oil (fat), mineral, ash content etc to have an idea about the energy contained in that matter.
Proximate analysis includes determining the moisture content, volatile matter, fixed carbon, and ash content of a sample. It provides important information about the composition and energy content of materials such as coal, biomass, and solid waste. These parameters help in understanding the suitability of a material for various applications, such as combustion or conversion to energy.
because the proximate is just to find the crude one only and they are denatured by heat.
in proximate analysis of food, you determine for moisture content in the food, you determine for ashing, you determine for protein, crude fiber and so on
