The procedure for ash content determination in food samples begins with the selection of a sample that is believed to be representative of the entire portion. Then, the food is vaporized by dry ashing causing all minerals and water to be burned off.
1-determination of ferrous [Fe+2] ion in a sample solution in(g\L).2-determination of (ferrous and ferric )in a mixture. 3-determination of purity of KClO3 sample. 4-determination of [fe+2] in unknown sample. 5-determination of total iron [Fe] in an iron ore. 6-determination of [Fe+3] in a sample. 7-determination of available chlorine in bleaching powder.
Fasting is required for triglyceride determination because levels of triglycerides in the blood can be affected by recent food intake. Fasting helps ensure accurate test results by standardizing the conditions under which blood samples are collected. Eating food can temporarily elevate triglyceride levels, which may lead to incorrect interpretation of test results.
If the temperature of drying is too high, or the drying is carried out for too long, there may be decomposition of some of the heat-sensitive components in the food. This will cause a change in the mass of the food matrix and lead to errors in the moisture content determination. It is therefore normally necessary to use a compromise time and temperature, which are sufficient to remove most of the moisture, but not too long to cause significant thermal decomposition of the food matrix. http://people.umass.edu/~mcclemen/581Moisture.html

No, by determination and willpower
Oxygen is used in food calorimeters because it is a necessary element for the combustion of food samples. During the process of burning food to measure its energy content, oxygen is required to facilitate the reaction and ensure complete combustion, which determines the amount of energy released during the process.
Glucosazone is used as a reagent in the qualitative determination of reducing sugars, such as glucose, in various food products and other samples. It reacts with reducing sugars to form colored compounds, allowing for visual detection and quantification of the sugars present.
You can contact the manufacturer and ask if they have samples. I've done this before. There are also several web sites that catalog various free samples, for which you can apply.
The housekeeping procedure of food and beverage deals with the practices of the front office services. The housekeeping procedure also deals with the security, emergency and safety of food and beverage.
The food you eat will have no effect on sperm determination.

Pros: Accurate measurement of energy content in food or fuel samples, precise control over experimental conditions, and reliable results for calculating calorific values. Cons: Expensive equipment, time-consuming process to operate and analyze samples, and limited to measuring only the energy from combustion reactions.
