Brand: Macherey-Nagel GmbH & Co. KGAvailable in 6 variantsExtraction mixtures for sample preparation for determination of pesticides in food samples.MACHEREY-NAGEL offers a number of individually weighed and pre-mixed buffers and extraction mixtures, specially composed for different sample matrices.Mix I and Mix II are extraction mixtures, Mix III to Mix VI are clean-up mixtures.The food samples will be extracted with either Mix I or Mix II.Afterwards they will be purified with one of the following mixtures:Mix III (samples with low fat content; e.g. apples, strawberries),Mix IV (moderate content of chlorophyll and carotinoids; e. g. carrots, lettuce),Mix V (high content of chlorophyll and carotinoids; e. g. bell peppers, spinach),Mix VI (high fat content; e. g. avocados).Every mix is prepacked in a 15 ml centrifuge tube. Pack of 50 pieces.
