This analytical procedure specifies a reverse phase high performance liquid chromatographic with UV detection (RP-HPLC-UV) method for the simultaneous determination of four authorized carotenoids in fish compound feed, namely astaxanthin (AXN), canthaxanthin (CXN), adonirubin (ADR) and astaxanthin dimethyldisuccinate (AXN DMDS), and of six authorized carotenoids in poultry feed, namely canthaxanthin (CXN); capsanthin (CSN), ethyl ester of beta-apo-8'-carotenoic acid (BACARE), citranaxanthin (CIXN), lutein (LUT) and zeaxanthin (ZEA) at levels ranging from ca. 2 to ca. 4 500 mg/kg (depending on the carotenoid). Beta-carotene (BCAR), authorized in compound feed for all animal species, was also added to the scope. The analytical procedure is fit for the purpose of quantitation of declared carotenoids and labelling confirmation. The procedure applies to natural and synthetic feed additives.

Xanthophyll esters like those of lutein, zeaxanthin and capsanthin that might be present in feed materials are not authorized feed additives and therefore not part of the scope of this method.

This document specifies a method for the gas-chromatographic determination of nicotine in total particulate matter from the mainstream smoke. The smoking of cigarettes and the collection of mainstream smoke are normally carried out in accordance with ISO 4387.

NOTE 1 ISO 20778 and ISO 22253 provide the determination method of nicotine in smoke with an intense smoking regime.

NOTE 2 In countries not in a position to use the gas-chromatographic method, reference is made to ISO 3400 for the determination of total nicotine alkaloids. In such cases, values obtained using the method described in ISO 3400 can be used with the addition of a note in the expression of results.
