Description

Application

• Transition of Psychotropic Drugs in Japanese Pharmacopoeia.: Discusses the evolution of the standards and test methods for Potassium Bromide, comparing Japanese Pharmacopoeia to USP and BP (Yanagisawa K, 2015).
• False hyperchloraemia in a dog due to potassium bromide.: Investigates an analytical chemistry error caused by potassium bromide in a veterinary context (Peacock RE et al., 2013).
• Standard and real patient kidney stone library using FTIR spectroscopy.: Utilizes potassium bromide in the development of a standard library for kidney stones using Fourier transform-infrared spectroscopy (Mulready KJ et al., 2012).
• Quantitative determination of solids by infrared spectroscopy.: Explores the use of potassium bromide disk technique for quantitative analysis in infrared spectroscopy (Jensen JB, 1958).
• Research on quantitative determination of solids.: Continues the discussion on the quantitative determination using the potassium bromide disk technique in infrared spectroscopy (Jensen JB, 1958).
