Methods of Testing Petroleum and Associated Products Test for Ethyl
Mercaptan Odourant in Propane...
Intended for the semi-quantitative (i.e. ± 25%) determination of
ethyl mercaptan odourant (within the range of 5 to 85 mg/L) in
liquid propane. It is particularly appropriate to confirm that
recently stenched propane is indeed odourized to the required
level. The method is intended for field application, and may be
suitable for use by non-laboratory personnel after suitable
training. A…
Ground (powdered) paprika — Determination of total natural colouring matter content
The method consists in extracting of the natural colouring matter content with acetone, measuring of the absorbance of the solution obtained using a spectrometer at a wavelength of 460 nm.
