An aqueous solution containing 2 g of glucose and 2 g of fructose per 100 g of solution contains 2/100=2% glucose on a wet basis, but 2/4=50% glucose on a dry basis.If the solution had contained 2 g of glucose and 3 g of fructose, it would still have contained 2% glucose on a wet basis, but only 2/5=40% glucose on a dry basis.
Analysis is fairly straightforward, with the coal thoroughly burnt and the ash material expressed as a percentage of the original weight. It can also give an indication about the quality of coal. Ash content may be determined as air dried basis and on oven dried basis.
An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.
In the determination, a sample is weighed in a heat-resistant crucible, dried at 105±2 °C, and ignited in a muffle furnace at 525±25 °C. The ash content is then determined, on a moisture-free basis, from the weight of residue after ignition and the moisture content of the sample.
A 19th-century assay laboratory in Tombstone Courthouse State Historic Park, Arizona. A model of a late 19th-century Canadian ( Yukon ) seal used to certify the quality of assayed gold . A metallurgical assay is a compositional analysis of an ore , metal , or alloy , usually performed in order to test for purity or quality.
It’s a rivalry unlike any other. Sure, there’s intensity in many other high-profile games. There’s pomp and circumstance every weekend in college football. There’s history and pride on the ...
So 138 g of dried apple contains 93.8 g dry matter and 675 mg potassium (0.72/100 x 93.8 g). When formulating a diet or mixed animal feed, nutrient or mineral concentrations are generally given on a dry matter basis; it is therefore important to consider the moisture content of each constituent when calculating total quantities of the different ...
