Potassium bromide density is a property of the chemical compound. It is used in many industrial applications, such as heat stabilizer in nylon production. In addition, it has been used as an anticonvulsant for centuries.
The ionic bonding of potassium bromide is a strong electrolyte. Thus, it is effective in high sulfate and carbonate ion concentrations. However, potassium bromide has zero optical absorption. This causes the substance to appear as white grains in aqueous solution.
For example, in a potassium bromide density gradient, the density can be adjusted by smoothing the discontinuous gradient during a run. Therefore, the density adjustment is less precise than in the equilibrium dialysis. But the amount of HDL rises to the top of the gradient more than in the conventional method.
A zinc bromide/potassium bromide base fluid was prepared by combining 77 wt.% ZnBr2 with 38 wt.% KBr. It was then blended with a formation brine consisting of water, sodium isoascorbate, and sodium thicyanate. After mixing, the fluid was equilibrated at 25degC and dried for 40 min.
Then, the sporocysts were purified by using a potassium bromide discontinuous density gradient. They were then introduced into cell cultures. Their morphology was determined by microscopic analysis. Finally, their viability was verified by a propidium iodide exclusion assay.
Calcium-free fluids formulated from alkali metal bromides are known to be corrosive under operating conditions. They also contain traces of oxygen, which could lead to corrosion when they are used in well completion.
