Witrynaimpurities, containers, sample preparation devices, volatile organics introduced as a result of handling personal care products, and even columns themselves. Plasticizers from labware can interfere with LC-MS, resulting in the need to lengthen the chromatography run in order to resolve these peaks from analyte peaks. WitrynaThis guideline presents a process to assess and control elemental impurities in the drug product using the principles of risk management as described in ICH Q9. This process provides a platform for developing a risk-based control strategy to limit elemental …
Witryna10 lip 2024 · Because this index is used in binary target variables (0,1), a gini index of 0.5 is the least pure score possible. Half is one type and half is the other. Dividing gini scores by 0.5 can help intuitively understand what the score represents. 0.5/0.5 = 1, meaning the grouping is as impure as possible (in a group with just 2 outcomes).
