Ammonium Thiosulfate,CAS : 7783-18-8

E FORU specializes in producing high purity Ammonium Thiosulfate,CAS : 7783-18-8 with the smallest possible average grain sizes,Purities may include 99%, 99.9%, 99.99%, 99.999% and 99.9999%, which are sometimes referred to as 2N, 3N, 4N, 5N and 6N. 99.99995% (6N5), and in some cases up to 99.99999% (7N) and 99.999999% (8N),E FORU produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Our standard powder particle sizes average in the range of - 325 mesh, - 200 mesh,- 100 mesh, 10-50 microns and submicron ( 12 micron). We can also provide in the nanoscale range.Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas..Ammonium Sulfates are double salts in the class of alums, compounds which contain a monovalent cation such as ammonium and a multivalent metal ion such as aluminum. Many alums occur in various hydrated forms as various rare minerals, but they are generally produced synthetically for commercial use. Many alums have common names: ammonium aluminum sulfate is often referred to as ammonium alum or just alum, ammonium iron(III) sulfate is sometimes known as iron alum, and ammonium iron(II) sulfate is known as Mohr’s salt..Quality inspection department staff which uses atomic spectroscopy, x-ray diffraction analysis, scanning electron microscopy, glow discharge mass spectroscopy (GDMS), and BET surface area analysis, among other technologies, to ensure that the elemental composition and structural properties of each product rigorously adhere to our standards.Additional technical, research and safety (MSDS) information is available,
