flotation method

flo·ta·tion meth·od

any of several procedures for concentrating helminth eggs for more reliable results when eggs are difficult to find in direct examination; the flotation methods depend on flotation of helminth eggs on the surface of a liquid of sufficiently high specific gravity, approximately 1.180; one part feces mixed in about 10 parts saturated saline will float most protozoan cysts and nonoperculated helminth eggs.

The flotation method is generally based on the different capacity of halite and sylvite surface to be moisturized with water through the addition of exclusively acting chemicals.
The results of this study showed that the use of the magnetic separation method as a pre-concentration method for floatation is more suitable than using the flotation method as a pre-concentration method for magnetic separation.
A total of 348 fecal samples from 32 avian species were examined using the Mini-FLOTAC flotation method. Parasites were detected in 31% (45/145) of samples from captive birds and in 65.5% (133/203) of samples from free-ranging birds.

The brown sugar flotation method detects greater percentages of larvae than the hot water method (Yee 2012), but as these are the only methods that have been evaluated, it would be useful to determine if variations or modifications of these methods can yield better results.
The copper will be extracted with the use of acid, unlike the flotation method used at Matchless and Otjihase mines.
We estimated egg age using the flotation method. Upon discovery eggs were carefully placed in a container of water and the angle at which the egg sat in the water column allowed us to estimate egg age using a generalised linear model constructed from eggs of known age (Cardilini 2010; Liebezeit et al.
