Colorimetric urea determination in presence of long hydrocarbon chain amidobetaine |
摘要 |
A colorimetric urea determination method, reagent, and reagent kit useful in end point and kinetic urea determination. Urea in a liquid sample reacts with o-phthalaldehyde and chromotropic acid or one of its salts in the presence of a linear long hydrocarbon chain amidobetaine to produce an intensely colored reaction product, the concentration of which is linearly related to the urea concentration in the sample.
