An assay on a dry basis refers to expressing the concentration of a substance in a sample after removing the moisture content. This method is commonly used in analytical chemistry to provide a more accurate representation of the actual substance content in a sample by eliminating the variability introduced by water content.

Is assay by mass balance equivalent to assay by as is basis?
No, assay by mass balance and assay by as is basis are not equivalent. Assay by mass balance calculates the amount of a component based on material balance equations, while assay by as is basis measures the amount of a component without accounting for any changes or losses that may occur during processing.
What is the difference between assay on as is basis and assay on anhydrous basis?
assay on as is basis includes the sample+water content+residual solvents+others. but assay on as is basis takes water content into account that means weight of the water present in the sample will be added in weighing the sample quantity of API required.
What is difference between anhydrous and dried basis?
1. anhydrous means : Means remove the water content & solvent free value calculated in the assay. 2. On dry base : Means remove the loss on dry & solvent free value calculated in the assay
What is an assay?
An assay is a scientific test or analysis used to measure the presence, amount, or activity of a substance or compound in a sample. Assays are commonly used in biology, chemistry, and medicine to study a wide range of biological and chemical processes.
How do you assay thrombin potency?
You can assay thrombin potency by measuring its ability to convert fibrinogen to fibrin, typically using a chromogenic or clot-based assay. The results are compared to a standard curve to determine the potency of the thrombin sample.
Is assay by mass balance equivalent to assay by as is basis?
No, assay by mass balance and assay by as is basis are not equivalent. Assay by mass balance calculates the amount of a component based on material balance equations, while assay by as is basis measures the amount of a component without accounting for any changes or losses that may occur during processing.
Difference between assay as is basis and dried basis?
Assay on 'as is' basis refers to the composition of a substance including its water content, while assay on 'dried' basis refers to the composition of a substance after removing the water content. Comparing these two types of assays can help in understanding the true chemical composition of a substance excluding the influence of water content.
What is the difference between assay on as is basis and assay on anhydrous basis?
assay on as is basis includes the sample+water content+residual solvents+others. but assay on as is basis takes water content into account that means weight of the water present in the sample will be added in weighing the sample quantity of API required.
How do you convert assay value from dried basis to as is bysis?
xx.x% on a dried basis implies that the material will have had all possible liquid impurities (water, solvents, residual liquid chemicals) removed by the drying process.Let's call w% is % of (water content, solvents, and residual) all combine. Your as-is value would be:xx.x% * (100 - w%)% as-is = ---------------------100Hopes that help.
What is difference between anhydrous and dried basis?
1. anhydrous means : Means remove the water content & solvent free value calculated in the assay. 2. On dry base : Means remove the loss on dry & solvent free value calculated in the assay
What is the difference between potency and assay?
Potency is the purity of the compound ;this states % available of the main component without water and residual solvents Assay is defined as Potency plus water and residual solvents and other remaining fractions please note assay can also be expressed as as is basis or dry basis Assay and Potency are same if assay is exprtessed as as is basis please note Potency word is mainly used for Antibiotics and bilogicals courtsey ; CDER , USFDA ; Dr.Uttam Krishna
Moisture content in dry basis convert to wet basis?
To convert moisture content from dry basis to wet basis, use the formula: MCwet = (MCdry / (1 - MCdry)) where MCwet is the moisture content on a wet basis and MCdry is the moisture content on a dry basis. For example, if the moisture content on a dry basis is 10%, the moisture content on a wet basis would be 11.1%.
What is protein assay?
Protein assay is the determination of concentration or total level of protein in a solution.There are various protein assays employed like bradford assay and lowry assay
What is ADB for coal?
ADB. Its means Air Dry Basis.
How do you calculate Assay of Ceftriaxone sodium BP on anhydrous basis?
To calculate the assay of Ceftriaxone sodium BP on an anhydrous basis, you first need to determine the molecular weight of Ceftriaxone sodium. Next, you would divide the weight of the anhydrous Ceftriaxone sodium by the total weight of the sample and multiply by 100 to get the percentage on an anhydrous basis. This calculation helps ensure accurate dosing and purity of the compound.
How do you verify gold bar assay certificate?
You can't verify assay certificates.
When was US Assay Commission created?
United States Assay Commission was created in 1792.
