For PCDD/PCDFs, detectable quantities shall be in the upper femtogram (10-15g) range because of extreme toxicity of some of these compounds. For most PCB congeners limit of quantification in the nanogram (10-9g) range is already sufficient. For the measurement of the more toxic dioxin-like PCB congeners (in particular non-ortho substituted congeners), the lower end of the working range shall reach the low picogram (10-12g) levels.

Feed (solid and liquid) can be packaged in bags, sacks, cans, barrels etc. which are referred to in the table as units. Large units (≥ 500kg or litres) have to be sampled in accordance with the provisions foreseen for loose feed (see points 5.1.1 and 5.1.2). (1)   In case it is not possible to make the liquid homogeneous, the number of incremental samples has to be increased.

This solution will be used as a reference solution against which to measure the blank test solution. Place the test sample in a ground-necked 250 ml flask, the bottom of the flask having been covered with crushed glass. Using a pipette, add 50 ml of solvent A (3.2), stopper the flask and mix for one hour in the mixer. Filter through a dry filter and collect the filtrate in a small ground-necked flask. The amount of test sample used depends on the presumed gossypol content of the sample.

Inject each calibration solution (3.10.3) several times and determine the mean peak heights (areas) for each concentration. Plot a calibration graph using the mean peak heights (areas) as the ordinates and the corresponding concentrations in μg/ml as the abscissae. Weigh to the nearest 0,01 g, from 5 g to 10 g of the sample into a 250 ml conical flask with stopper. Place the flask in an ultrasonic bath (4.1) at approximately 40 oC for 20 minutes, then remove and cool to room temperature. Allow to stand for about 1 hour until the suspended matter has settled, then filter an aliquot portion through a 0,45 μm membrane filter (4.2) into a suitable vessel.

  • Methyl benzoquate is extracted from the sample with methanolic methanesulfonic acid solution.
  • For products with a high content of oils and fats, which are difficult to crush or unsuitable for drawing a homogeneous reduced test sample, proceed as follows.
  • All flow cytometry data were analyzed using FlowJo, version 10.0.8, software (Treestar, Ashland, OR).
  • The nominal concentration of this solution is 6,72 IU vitamin A per ml.

Re-extract the organic layer for 1,5 minutes with a further 50 ml of hydrochlorid acid and combine with the first extract. Wash the combined acid extracts by swirling for approximately 10 seconds with 10 ml of ethyl acetate (3.4). For the purpose of this method, the blank feed shall be similar in type to that of the sample and on analysis halofuginone shall not be detected. (b) The weight of sample to be ashed is calculated from the approximate trace element content of the feed in relation to the sensitivity of the spectrophotometer used. For certain feed low in trace elements it may be necessary to start with a 10 to 20 g sample and make up the final solution to only 100 ml. For preparation of the reagents and analytical solutions use water free from the cations to be determined, obtained either by double distilling water in a borosilicate glass or quartz still or by double treatment on ion exchange resin.

It is necessary to carry out preliminary drying when dealing with solid feed which has high moisture content. Several methods determine a specific clean-up procedure. Unless otherwise specified in the methods of analysis, all analytical reagents must be analytically pure (a.p.).

Add 5,0 ml of sulfosalicylic acid solution (3.22), with stirring and continue to stir with the aid of magnetic stirrer for 5 min. Filter or centrifuge the supernatant in order to remove any precipitate. Take a quantity of clear filtrate appropriate for the presumed content of volatile nitrogenous bases (100 ml is usually suitable).

If it is not possible to analyse the hydrolysates the same day, they may be stored at 5 oC for a maximum of 3 days. Samples high in moisture must be either air-dried at a temperature not exceeding 50 oC or freeze dried prior to grinding. Samples with high fat content shall be extracted with light petroleum (3.9) prior to grinding. The standard solution is diluted with citrate buffer to give peak areas in the middle of the range. Samples with a high fat content shall be extracted with light petroleum (3.12) prior to grinding.

Prior to use filter through a 0,22 μm membrane filter (4.3) and degas the solution (e.g. in the ultrasonic bath (4.4) for at least 15 minutes). Dissolve 224,74 g of sodium perchlorate monohydrate in water (3.3) in https://professionalservicesanita.com/meltos-40-mcg-dosage-new-breakthrough-in-weight/ a ml graduated flask, make up to the mark with water (3.3) and mix. Dissolve 13,80 g of sodium dihydrogen phosphate monohydrate in water (3.3) in a ml graduated flask, make up to the mark with water (3.3) and mix.

Vitamin E acetate hydrolyses very fast under alkaline conditions and is therefore very sensitive to oxidation, especially in the presence of trace elements like iron or copper. In case of the determination of vitamin E in premixtures at levels higher than mg/kg, a degradation of vitamin E could be the consequence. Therefore a HPLC method including an enzymatic digestion of the vitamin E formulation without an alkaline saponification step is to be recommended for confirmation.
