study of high performance liquid chromatography grade water quality in iran

The use of high performance liquid chromatography (hplc) grade water is very important for laboratory studies, especially food quality control. these studies have a great impact on diagnosing food health. food health improves the health of the community and these two parameters are closely related. hplc grade water is ultra-pure water with low uv absorption ability. this water is often purified through a micron filter and all contaminants are removed. methods: thirty samples of hplc grade water with iranian and non-iranian brands purchased from tehran were tested for electrical conductivity and silica. results: the quality of all the tested samples was approved which was lower than the allowable limit. none of the iranian and non-iranian samples exceeded the standard limit. conclusion: this study indicated the good quality of this product. it was concluded that all the samples had desirable quality
