EN ISO 3696, Water for analytical laboratory use  Specification and test methods (ISO 3696:1987) 3 Principle FB1 and FB2 are extracted from the test material with a solution of 50% methanol in phosphate-buffered saline (PBS). The extract is then diluted with PBS and cleaned up using immunoaffinity columns (IAC). FB1 and FB2 are eluted from the IAC using methanol and then water. After volume adjustment, the eluate is directly injected into the HPLC and FB1 and FB2 are detected by their fluorescence after either pre- or post column derivatisation. 4 Reagents and materials During the analysis, unless otherwise stated, use only reagents of recognized analytical grade. Solvents shall be of HPLC or better quality and only double-distilled water or water of at least grade 2 as defined in
EN ISO 3696 shall be used. 4.1 Double distilled or deionised water (EN ISO 3696) 4.2 Methanol, CH3OH WARNING — Methanol is hazardous and handling should be carried out inside a fume cupboard. Appropriate safety equipment (lab coat, goggles, gloves) should be worn. 4.3 Acetonitrile, CH3CN WARNING — Acetonitrile is hazardous and handling should be carried out inside a fume cupboard. Appropriate safety equipment (lab coat, goggles, gloves) should be worn. SIST EN 16006:2011

PBS tablets, Phosphate buffered saline tablets one tablet dissolved in 200 ml of water (4.1) yields 0,01 mol/l phosphate buffer, 0,002 7 mol/l potassium chloride and 0,137 mol/l sodium chloride, pH 7,4, at 25°C (e.g. Sigma P4417). 4.17 Diluent Mix 50 parts per volume methanol (4.2) with 50 parts per volume water (4.1). 4.18 Extraction solvent Mix 50 parts per volume methanol (4.2) with 50 parts per volume of PBS (4.16).

This will result in 2,0 ml of a solution containing ca. 4 µg/ml FB1 & FB2 each in mostly methanol /water (50/50, v/v). 4.22 Calibration solutions From the diluted stock solution for calibration (4.21) prepare five levels of calibration solutions by adding the volumes of diluted stock solution listed in the following table to a volumetric flask (5.13) of the indicated volume and make up to the mark with diluent (4.17).
Calculate the concentrations of FB1 & FB2 for the different calibration levels by dividing the certified or calculated concentrations of the stock solution (4.20) by the final dilution stated below. Should you observe saturation of the detector signal at the highest calibration level dilute 250 µl of diluted stock solution into 2,0 ml for a final dilution of 100.

4.23 IAC (Immunoaffinity column) The immunoaffinity columns must contain a stationary phase with immobilized monoclonal antibodies specific to, at least, Fumonisin B1 and B2. To be suitable for this method they must meet the requirements stated below: An aliquot of more than 5 ml of an extract of a fumonisin-free representative compound animal feed material is spiked with FB1 & FB2 in equal parts at either 920 (high) ng/ml or 110 (low) ng/ml for the sum of both. Then dilute 5,0 ml of that spiked extract to a total volume of 50,0 ml (see 6.2). Following the procedures described in 6.3 and 6.4 this will result in expected concentrations in the injection solutions of either 460 ng/ml or 55 ng/ml for the sum of FB1 & FB2. After measuring (Clause 7) these solutions the observed concentrations of FB1 & FB2 can be calculated with Equation (1) and Equation (2) of Clause 8. Dividing the sum of the observed concentrations of FB1 & FB2 by the expected concentrations will result in the yie
