The residual amount of ethylenediamine tetracetic acid (EDTA) in canned food products was determined by adopting thin-layer chromatography (CTLC).
It usually will be advantageous to price out the ending inventory (and assign the residual amount to the cost of goods sold) because the ending inventory will involve fewer units than the cost of goods sold.
A capillary gas chromatographic method with directly sampling was established to determination the residual amount of methanol, ethanol and ethyl acetate in lansoprazole.
