Ion chromatography (IC) is an analytical technique used to separate and quantify ionic and polar analytes. IC has become widely accepted by the pharma industry and regulatory bodies for an expanded range of applications like water quality and chemical analysis. It has qualified in recent years to analyze pharmaceuticals. The United States Pharmacopeia-National Formulary (USP-NF, US Pharmacopeia ...

What are Isotopes? Isotopes are different atoms of the same element with the same number of protons and different numbers of neutrons called isotopes of each other, which can also be interpreted as different nuclides of the same element called isotopes of each other. An isotope is one of two or more atoms of the same chemical element with the same atomic number, occupying the same position on the ...
Quality control of hair, skin, and dentalcare products continues to increase in importance for producers. Aside from safeguarding our health, it is equally important to avoid the sale of out-of-specification products. Product recalls are very expensive and have a lasting effect on a company’s reputation. Therefore, intensive testing of these different care products is essential before ...
Drug analysis refers to the detection and analysis of ingredients and contents in drugs. Drug analysis and testing involves the study of composition, physical and chemical properties, purity, and the determination of the content of active pharmaceutical ingredients and their preparations, to ensure that the medications are safe, rational, and effective. Drug analysis and testing are very ...
The basic requirements of pharmaceutical preparations are safety, efficacy, and stability. Drug stability means that a drug product should maintain the same properties and characteristics as it was at the time of production and within the specified time frame. The stability of pharmaceutical preparations directly affects the effectiveness and safety of drugs. Therefore, it is of great ...
Changes in the endocrine potency of municipal wastewater at 3 wastewater treatment plants (WWTPs) in Australia were investigated using a panel of in vitro receptor‐driven transactivation assays. The assays were based on human estrogen receptor α, androgen receptor, progesterone receptor, glucocorticoid receptor, and peroxisome proliferator‐activated receptor γ2. Total removal efficiencies for ...
Abstract: The toxicity of 27 samples of effluents of three pharmaceutical plants located in Belgium, has been determined with the aid of a battery of tests. Besides conventional bioassays representative for three different trophic levels (microalgae withSelenastrum capricornutum, acute crustacean test withDaphnia magna, acute fish test withBrachydanio rerio), cost-effective acute bioassays have ...
X-ray radiography of soil cores was used as the primary test method to determine the reasons for the permeation of perchloroethylene into apparently impermeable clay layers at a hazardous chemical spill site. X-ray powder diffractometry, scanning electron microscopy, and chemical analysis were also performed to characterize the materials and structures observed in the soil cores through X ...
