Infrared (IR) spectroscopy

Infrared (IR) spectroscopy involves the interaction of infrared radiation with matter. It covers a range of techniques, mostly based on absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify and study chemical substances. Samples may be solid, liquid, or gas. The main use of this technique is in organic and inorganic chemistry. It is used by chemists to determine functional groups in molecules. IR methodology utilized by Accuon Labs to perform cost effective analysis of a wide array of products. Our team of experts performs to identify the wide range of organic compounds.

Residual solvents analysis

Residual solvents analysis is performing at Accuon Labs utilizing the preferred methodologies like Gas chromatography, Liquid chromatography and Mass spectroscopy. For pharmacopeia purposes, residual solvents in pharmaceuticals are deļ¬ned as organic volatile chemicals that are used or produced in the manufacture of drug substances or excipients, or in the preparation of drug products. The residual solvents are not completely removed by practical manufacturing techniques. Appropriate selection of the solvent for the synthesis of a drug substance or an excipient may enhance the yield, or determine characteristics such as crystal form, purity, and solubility. Therefore, the solvent may sometimes be a critical element in the synthetic process. Our scientists have the ability to analyze solids, liquids, and organic solutions for measurements different types of solvents (non-listed, Class-1, 2&3 solvents) with our state of the art instrumentation following the guidelines USP<467> and ICH Q3C. Accuon Labs will assure your product impurities will be controlled and within acceptable limits aiding you in meeting regulatory requirements for product submission.

Potentiometric titration

Potentiometric titration is a volumetric method in which the potential between two electrodes is measured (referent and indicator electrode) as a function of the added reagent volume. This methodology utilized by Accuon Labs to perform cost effective analysis of a wide array of products. Our team of experts performs to assay and content of organic and inorganic compounds.

Karl Fischer titration

Karl Fischer titration is a widely used analytical method for quantifying water content in a variety of products. The fundamental principle behind it is based on the Bunsen Reaction between iodine and sulfur dioxide in an aqueous medium. This methodology utilized by Accuon Labs to perform water content of a wide array of products.

Stability studies

The purpose of stability testing is to provide evidence on how the quality of a drug substance or drug product varies with time under the influence of a variety of environmental factors such as temperature, humidity, and light, and to establish a re-test period for the drug substance or a shelf life for the drug product and recommended storage conditions. Accuon Labs ability to conduct stability studies (Accelerated, Long-term, intermediate and PHOTO stability) following the guidelines ICH Q1. Accuon Labs will assure your product will be controlled and within acceptable limits aiding you in meeting regulatory requirements for product submission.
