To convert proximate analysis of coal to ultimate analysis, use the Dulong formula as follows: Carbon = 0.75*(fixed carbon + [volatile matter/100]); Hydrogen = 0.06volatile matter; Oxygen = [moisture/100] + 0.3sulfur - carbon - hydrogen; Nitrogen = volatile matter/100 * 0.01. This formula estimates the ultimate analysis (C, H, O, N) from the proximate analysis (moisture, volatile matter, fixed carbon, ash).
Proximate analysis determines the moisture, ash, volatile matter, and fixed carbon content of a substance, while ultimate analysis determines the elemental composition (carbon, hydrogen, nitrogen, sulfur, oxygen) of a substance. Proximate analysis provides information on the physical and chemical properties, while ultimate analysis provides information on the elemental composition.
Proximate analysis determines the basic chemical composition of a feed sample, focusing on moisture, crude protein, fat, fiber, and ash content. Weende analysis is a specific method of proximate analysis that focuses on determining the crude protein, fat, fiber, and nitrogen-free extract content of feed samples. In summary, while proximate analysis is a broader term, Weende analysis is a specific method within proximate analysis that focuses on certain components.
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.
Proximate analysis is important because it provides information on the major components of a sample such as moisture, ash, volatile matter, and fixed carbon. This analysis helps in assessing the quality and energy content of a material, which is crucial in various industries like food, fuel, and agriculture. By understanding the proximate composition, producers can make informed decisions about processing, handling, and utilization of materials.

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 of fat can be done by using soxhlet apparatus
It is proximate.
Proximate analysis determines the basic chemical composition of a feed sample, focusing on moisture, crude protein, fat, fiber, and ash content. Weende analysis is a specific method of proximate analysis that focuses on determining the crude protein, fat, fiber, and nitrogen-free extract content of feed samples.

Proximate analysis is important because it is one of the most effective ways to analyze nutritional value and energy value in food.
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

Proximate questions focus on the immediate causes and mechanisms of behavior, such as genetic, physiological, or environmental influences. Ultimate questions, on the other hand, are concerned with the evolutionary reasons behind behavior, such as how it has contributed to reproductive success or survival over time.
Proximate causes refer to immediate triggers or mechanisms that directly lead to a particular outcome. Ultimate causes, on the other hand, delve deeper into the evolutionary or historical reasons behind why a trait or behavior exists. Ultimate causes are about understanding the broader context and long-term implications, while proximate causes focus more on the immediate factors at play.
