Other methods, such as liquid chromatography (LC) mass spectrometry (MS) method, high-performance liquid chromatography (HPLC) with appropriate detection, immunoassays and functional assays, such as the phosphatase inhibition assay, can be used as alternatives or supplementary to the EU-RL LC-MS/MS method, provided that:

to preconcentrate analytes in chromatographic methods (e.g. high performance liquid chromatography (HPLC), gas chromatography (GC) adsorption chromatography), atomic absorption spectroscopy (AAS), inductively coupled plasma spectroscopy (ICP), X-ray fluorescence analysis;

Question No. 419 Ms. Kirsty Duncan: With respect to the risk of corrosion and spills and other safety concerns arising from the transport of bitumen in pipelines, and to government action to address these risks: (a) how does diluted bitumen compare with West Texas Intermediate (WTI) in terms of (i) abrasive material content, (ii) acid concentration, (iii) sulphur content, (iv) viscosity; (b) to what extent is diluted bitumen more likely than WTI to cause corrosion or erosion in the pipelines through which they respectively flow; (c) what is the composition of diluted bitumen in Canada; (d) what are all of the volatile chemicals, persistent organic pollutants or carcinogenic substances present in diluted bitumen in Canada; (e) in the pro ...[+++]cess of diluting bitumen in Canada, what are the (i) natural gas condensates used, (ii) other petroleum products used; (f) what is the process by which diluted bitumen corrodes pipelines, with specific reference to (i) abrasion, (ii) friction, (iii) high pressure, (iv) settling of sediment, (v) velocity, (vi) sulphur-reducing bacteria, (vii) other significant factors; (g) for all proposed or existing National Energy Board (NEB)-regulated pipelines, what is (i) the amount of hard sediment passing through the pipeline annually, (ii) the average pressure, (iii) the average temperature; (h) what, if any, (i) research, (ii) action, (iii) investment has the government undertaken to determine whether diluted bitumen can flow safely through pipelines; (i) what, if any, (i) research, (ii) action, (iii) investment has the government undertaken to determine whether or not conventional crude should be distinguished from diluted bitumen when setting minimum standards for pipelines; (j) what, if any, (i) research, (ii) action, (iii) investment has the government undertaken to design safety and spill responses and spill liability management capabilities that are appropriate specifically to diluted bitumen; (k) how does a diluted bitumen sp ...

Well, when you sell a natural herb that that product is extracted from, when you run a mass spec or a high-pressure liquid chromatograph on it, yes, that molecule is there.

For those anionic surfactants not reacting to the abovementioned MBAS method, or if it seems more appropriate for reasons of efficiency or precision, appropriate specific instrumental analyses such as high performance liquid chromatography (HPLC) or gas chromatography (GC) are to be applied.

Depending on the results, the identification is confirmed by high performance liquid chromatography (HPLC) or, in the case of propionic acid, by gas chromatography (GC).
