Sea Water Testing

Sea water contains a variety of organic, inorganic, dissolved, and suspended materials. The analysis result of sea water is greatly influenced by the characteristics of sea water itself. For example, a large number of salts can have influence on the determination and activity of organic matter and microorganisms, especially when analyzing trace or ultra-trace components, there are some specific requirements about the separation, enrichment, and measurement methods of samples.

STEMart can provide you with a variety of testing services to analyze the main elements, nutrients, trace elements or organic compounds in sea water.
