MC gives only % of water in a substance(Low melting range substance).But LOD result is a combination of water content and other volatile organic solvents.And more over Melting range of a substance has to be considered in case of LOD. Substances whichever is having high melting point is required for LOD checking.
LOD (Loss on Drying) is a method used to measure the moisture content of a material by weighing it before and after drying to remove the moisture. Moisture content is the amount of water present in a material, usually expressed as a percentage of the total weight. LOD is a specific analytical technique, while moisture content is a more general term describing the water content in a substance.

What is the difference between Karl fisher and loss on drying?
Karl Fischer titration is a method for determining water content in a sample by using a titrant that reacts specifically with water. Loss on drying (LOD) is a technique that involves heating a sample to evaporate volatile components, such as water, and measuring the weight loss as a percentage of the initial sample weight. Karl Fischer is more precise and specific for water determination, while LOD is a general method that can include other volatile substances as well.
How do you calculate lod and loq by hplc give example?
The Limit of Detection (LOD) and Limit of Quantitation (LOQ) can be calculated using the signal-to-noise ratio method. For example, LOD is typically calculated as 3 x standard deviation of the blank signal divided by the slope of the calibration curve. LOQ is typically calculated as 10 x standard deviation of the blank signal divided by the slope of the calibration curve. Both LOD and LOQ are important parameters to determine the sensitivity and reliability of an HPLC method.
How do you calculate the limit of detection from a calibration curve?
The limit of detection (LOD) can be calculated as 3 times the standard deviation of the y-intercept divided by the slope of the calibration curve. This value represents the smallest concentration of analyte that can be reliably measured with the method.
What Loss on drying formula for solid powder forms?
The Loss on Drying (LOD) formula for solid powder forms is typically calculated as: LOD (%) = ((Initial weight - Final weight) / Initial weight) x 100 Where: Initial weight is the weight of the sample before drying. Final weight is the weight of the sample after drying.
What are the substances that are soluble in water?
Substances that are soluble in water include salts (e.g. sodium chloride), sugars (e.g. sucrose), acids (e.g. hydrochloric acid), bases (e.g. sodium hydroxide), and some gases like oxygen and carbon dioxide. Polar molecules and ionic compounds tend to be soluble in water due to its ability to form hydrogen bonds and interact with charged particles.
What is difference between Loss on drying and moisture content?
LOD is that the loss throughout drying of sample as per prescribed conditions which supplies loss (presence) of all evaporating solvents together with water.It is the dry base. While water content provides the moisture present within the sample solely. It is unhydrous base.
What is the difference between moisture and loss on drying?
Moisture content refers to the total amount of water present in a material, while loss on drying is a method used to determine the amount of moisture in a sample by measuring the weight lost after drying it. Loss on drying involves heating a sample to evaporate moisture, which is different from directly measuring the total amount of water present in a material.
What is difference between LOQ and LOD?
LOQ (Limit of Quantification) is the lowest concentration of an analyte that can be reliably quantified, while LOD (Limit of Detection) is the lowest concentration that can be reliably detected but not necessarily quantified. LOQ usually has a higher value than LOD because it involves quantification, which requires a higher level of accuracy.
Should water content or LOD be subtracted from potency?
Whichever is higher in value should be subtracted
What is LOD in pharmaceuticals?
What is LOD in pharmaceuticals? In my experience, it can mean 2 things: Level of Detection, as in how much of the drug is detected in a sample (blood, urine, etc) Line of Drug, as in this is an Oncology drug.
