What is the difference between assay on as is basis and assay on anhydrous basis?
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.
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 assay used to measure invertase actiivity?
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.
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.
What is the difference between assay on as is basis and assay on anhydrous basis?

What is Sheffield?
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.
