A special patch is applied to the surface to be tested, and a specified volume of deionized water is injected under the patch.
The nutritional value of sea salt and table salt are about the same as they are both primarily sodium chloride. [15] [16] Table salt is more processed than sea salt to eliminate minerals and usually contains an additive such as silicon dioxide to prevent clumping.
