Go to your local gym. they will have body composition scales which test composition by electrical resistance in your body. They are also traines in skin fold techniques which is also pretty accurate.
Body composition is the ratio of body fat to muscles.

Analytical chemistry is the study of methods used to determine the chemical composition of materials.
A common instrument used to determine body fat is a body fat caliper, which measures skinfold thickness at various sites on the body to estimate body fat percentage. Other methods include bioelectrical impedance analysis (BIA) devices, which send a low electrical current through the body, and dual-energy X-ray absorptiometry (DEXA) scans, which provide detailed images of body composition. Each method has its advantages and varying degrees of accuracy.

The body composition is a series of tests used to compare the proportion of fat mass to lean mass. Fat mass is defined is the essential fats plus the stored fats.

Either the amount of heat released from the body in sealed chamber or oxygen consumed by body in sealed chamber can be used to determine a person's metabolic rate.
The purpose of stellar spectroscopy is to determine the chemical composition of stars, the temperature and some other characteristcs..
