一般描述

This certified eluent concentrate for ion chromatography is traceable by potentiometric titration to NIST Standard Reference Material. It is certified in accordance with ISO Guide 31. All details about exact content, uncertainty, traceability and expiry date are described in the certificate.
Sulfuric acid (hydrogen sulfate, sulphine acid,battery acid) is a clear, colorless, oily liquid and is very corrosive in nature towards both metal and tissues. It is soluble in water.

应用

Metrohm IC application noteAN-S-344:Anions in "Electronic grade" nitric acid on a high-capacity column.

Metrohm IC application noteAN-S-341:4-Hydroxybutyrate in addition to standard anions and organic acids.

Metrohm IC application noteAN-S-336:Anion traces on the Metrosep A Supp 16 - 250/2.0 after Inline Preconcentration and Matrix Elimination

生化/生理作用

It finds application in the manufacture of explosives, fertilizers, glue and other acids. It is also used in the pickling of metal, purification of petroleum, and in lead-acid batteries. It is widely used as dehydrating agent, catalyst, and as an active reactant in chemical industry. It is also suitable to control pH, ranging from saline solutions to strong fuming acids.
Sulfuric acid is prepared by dry distillation of minerals like copper sulfate pentahydrate (blue vitriol), and iron sulfate heptahydrate (green vitriol). On application of heat these compounds decompose to form iron and copper oxides thereby eliminating water and sulphur trioxide, which then combine to give, dilute solution of sulphuric acid.

Nucleation of aerosol particles from trace atmospheric vapours is thought to provide up to half of global cloud condensation nuclei. Aerosols can cause a net cooling of climate by scattering sunlight and by leading to smaller but more numerous cloud

Atmospheric new-particle formation affects climate and is one of the least understood atmospheric aerosol processes. The complexity and variability of the atmosphere has hindered elucidation of the fundamental mechanism of new-particle formation from gaseous precursors. We show, in experiments performed

Although p53 is found mutated in almost 50% of all cancers, p53 mutations in leukaemia are relatively rare. Acute myeloid leukaemia (AML) cells employ other strategies to inactivate their wild type p53 (WTp53), like the overexpression of the p53 negative

Atmospheric aerosols formed by nucleation of vapors affect radiative forcing and therefore climate. However, the underlying mechanisms of nucleation remain unclear, particularly the involvement of organic compounds. Here, we present high-resolution mass spectra of ion clusters observed during new particle
