Web1. Instructions for performance of assay The amount of citric acid present in the assay has to be between 1 g and 80 g. In order to get a sufficient absorbance difference, the sample solution is diluted to yield a citric acid concentration between 0.04 and 0.4 g/l. 1 The absorption maximum of NADH is at 340 nm. On spectrophotometers, measurements WebTransfer the 5.0-mL sample of citric acid solution for trial 1 from the cylinder into a 125-mL Erlenmeyer flask. Empty the cylinder totally, by waiting until the last drops fall. Add …
WebThe assay is specific for citric acid. In the analysis of commercial citric acid monohydrate,results of > 100 % can be expected,due to partial loss of the water of crystallisation. The smallest differentiating absorbance for the assay is 0.005 absorbance units. This corresponds to 0.460 mg/L of sample solution at the maximum sample … WebCitric acid is a weak organic acid and a solid, making it safer than the other three; but it is much less effective, and therefore more expensive to use. Use the Correct Injector. Once you choose an acid to use, make sure your injector can handle the task. Read the injector manual to get this information or call the manufacturer of the injector.
