The concentration of the standard and sample is one of the most critical information to perform various method validation parameters. The inaccurate analyte concentration may lead to deviation or rework. How one can define the required concentration of sample/standard for the validation parameters? Let us explore….

Chromatography of charged analytes is often challenging as they are not retained effectively on the commonly used reversed-phase columns. Ion pair chromatography (IPC) is a suitable alternative for chromatography of polar or ionic species. Let us understand the retention of charged analytes in IPC.

The inlet liner isolates the sample from the metal walls of the injector block. The vaporization, speed of the sample, and backflash are some of the routine challenges for GC. How does an inlet liner with a “hole” helps in resolving some of these challenges?

FDA and EMA have agreed upon a “Carcinogenic Potency Categorization Approach” to predict the AI Limits for Nitrosamines and NDSRIs. The Nitrosamines are categorized into 5 different Potency Categories based on α hydrogen score, deactivating features score, and activating features score. Both FDA have provided a few configurations for calculating the α hydrogen score, whereas, a few are missing. ▶️Follow this link to join my WhatsApp group: https://chat.whatsapp.com/Jrem91dAOsG3Aob4kRQpZd Regards Bhaskar #nitrosamine #NDSRI #AI #CPCA #EMA #FDA #PharmaGrowthHub #riskassessment
