LaoAssay 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.

How do you convert assay value from dried basis to as is bysis?
To convert an assay value from dried basis to as-is basis, you need to adjust for the moisture content. The formula for this conversion is: As-is assay value = Dried assay value / (1 - Moisture content). For example, if the dried basis assay value is 90% and the moisture content is 5%, the as-is basis assay value would be 90% / (1 - 0.05) = 94.74%.
What is the relation between ADB and AD for coal testing?
ADB (Air-Dried Basis) and AD (As-Delivered Basis) are two different methods of expressing the moisture content of coal. ADB refers to the moisture content of coal after it has been air-dried, while AD includes the moisture present in the coal as it is delivered to the end user. The conversion between ADB and AD allows for accurate comparisons of coal quality for various purposes.
WHAT IS AS DRIED BASES AND AS RECEIVED BASES IN COAL?
As-dried basis in coal refers to the coal's composition when all moisture has been removed, while as-received basis includes the naturally occurring moisture content. As-dried basis is commonly used for comparing coal qualities, as it eliminates the variable of moisture content. On the other hand, as-received basis reflects the coal's properties as it is found in its natural state.
What is the meaning of adb in coal specification?
ADB stands for Air Dried Basis in coal specification. This term refers to the moisture content of coal after it has been air dried under specific conditions. It is used to standardize coal analysis and compare the energy content of different coal samples.
What is the difference between hay straw and propane?
Hay is dried grass used as animal feed or bedding, straw is the dry stalks of cereal plants used for animal bedding or mulch, and propane is a colorless gas used as a fuel for heating, cooking, and powering vehicles. They are all different in their composition, purpose, and usage.
