Assay on as is basis refers to the percentage of a substance in its current state, including any impurities or water content present. Assay on anhydrous basis, on the other hand, refers to the percentage of a substance calculated without including any water content present. This difference is important when comparing the purity of substances or calculating accurate concentrations in chemical analysis.
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.
The most common assay used to measure invertase activity is the DNS method, which involves measuring the release of reducing sugars from sucrose using dinitrosalicylic acid. This assay is based on the colorimetric detection of reducing sugars, which allows for the quantification of enzyme activity. Other methods include the Nelson-Somogyi method and the Nelson-Somogyi 3,5-dinitrosalicylic acid method.
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.
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.

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
No, assay by mass balance and assay by as is basis are not equivalent.

You can't verify assay certificates.
In common with many other countries, all valuable metals in the UK are assayed and stamped to verify their purity. There are several regional assay offices in the UK, each one having their own specific mark. The Sheffield assay office was opened in 1773 and has been in continuous operation since. The current assay mark is the Yorkshire Rose. Prior to 1977, it was a crown.
United States Assay Commission was created in 1792.
United States Assay Commission ended in 1980.
The old miners in gold rush country took their nuggets to the local Assay Office, to determine -- to assay -- the value of the metal in their nuggets.
A bandshift assay is a type of assay using gel electrophoresis, in which the mobility of a DNA or RNA probe alone is compared to its mobility in combination with a particular protein.

"Assay", and "test" are potential synonyms for the word 'titrate'. The term is mainly used in the Chemistry to measure concentration of chemically active groups of substances such as acids and bases.
