Incorporating a sensor with completely PFA perfluoroalkoxy wetted parts, size is optimized to the absolute limit. Employing a sensor with a sanitary structure, using only PFA as the wetted material. Being a chemically resistant sensor, it is capable of measuring various chemicals used in semiconductor processes. Concentration conversion is possible by inputting the relationship between chemical concentration and conductivity along with temperature characteristics. It is particularly suitable for the dilution management of low-concentration chemical solutions. Masz pytania lub prośby? Skorzystaj z tego formularza, aby skontaktować się z naszymi specjalistami.

In recent years, there has been a continuous increase in the incidence of urolithiasis, especially in highly developed countries. Therefore, the question arises which factors specific to these countries may be responsible for the increase in the incidence of this disease. In this article, we try to assess the effect of phosphoric acid, a component of various carbonated drinks, including Coca-Cola, on the nucleation and growth of struvite crystals, which are the main component of infectious urinary stones. The research was carried out in the environment of artificial urine with and without the presence of Proteus mirabilis bacteria. In the latter case, the activity of bacterial urease was simulated by adding an aqueous ammonia solution. The obtained results indicate that phosphoric acid present in artificial urine causes the nucleation of struvite to shift towards a lower pH, which means that struvite nucleates earlier in artificial urine compared to the control test. The amount of struvite formed is the greater the higher the concentration of phosphoric acid. At the same time, as the concentration of phosphoric acid increases, the growing struvite crystals are larger, which is disadvantageous because they are more difficult to remove from the urinary tract along with the urine. For the highest levels of phosphoric acid tested, large dendrites are formed, which are particularly undesirable as they can damage the epithelium of the urinary tract. The effect of phosphoric acid on the nucleation and growth of struvite is explained in base of chemical speciation analysis. It should be keep in mind that all these effects of phosphoric acid are possible when the urinary tract is infected with urease-positive bacteria.

EC number: CAS number: For the inhalation route there is no animal study available. Therefore, oral rat data is used to calculate a corresponding air concentration for humans and a route-to-route extrapolation for systemic effects is necessary to derive the correct starting point. In the case of oral-to-inhalation the inclusion of a default factor of 2 is recommended according to chapter R. According to Figure R. For the dermal route there is no animal study available.

Phosphoric acid orthophosphoric acid, monophosphoric acid or phosphoric V acid is a colorless, odorless phosphorus -containing solid , and inorganic compound with the chemical formula H 3 P O 4. It is a major industrial chemical, being a component of many fertilizers. The compound is an acid. Phosphoric acid forms esters , called organophosphates. The name "orthophosphoric acid" can be used to distinguish this specific acid from other " phosphoric acids ", such as pyrophosphoric acid. Nevertheless, the term "phosphoric acid" often means this specific compound; and that is the current IUPAC nomenclature. Phosphoric acid is produced industrially by one of two routes, wet processes and dry. In the wet process, a phosphate-containing mineral such as calcium hydroxyapatite and fluorapatite are treated with sulfuric acid. Calcium sulfate gypsum, CaSO 4 is a by-product, which is removed as phosphogypsum.
