Quantity Maximum permitted

The verification of compliance with the specific migration limits (SML) provided in the Directives may be replaced by the verification of compliance with the maximum permitted quantity of substance in the finished product (QM), which corresponds to the SML. The correspondence between the specified SML and the QM shall be established by a calculation based on adequate experimentation of the finished product or by the application of generally recognized diffusion models. However, if the limit of QM is exceeded, for a judgement of non compliance of the material or article, it is necessary to obtain a confirmation that the SML has been exceeded .

Use Poultry feed in quantities less than 5% as a nonnutritive bulking agent, pelleting or anti-caking agent and nutrient carrier in dog and ruminant feeds. For dog feeds the maximum permitted is 1.5%. Labeling must state content when in excess of 1%. 

Figure 1 shows narrow range high resolution scans of the molecular ion region of NDMA, recorded near the maximum of the GC peaks, present in one of the beer samples prepared in the AOAC collaborative study. The peak at m/z 74.0480 represents approximately 0.15 ng of NDMA injected on the column, corresponding to a concentration of 0.6 yg/kg of beer. Use of high resolution MS permitted confirmation of the identity and amount of nitrosamine without additional cleanup of the concentrate prepared by the AOAC method. Sample quantity requirements were comparable to those of the TEA. 

The two types of MBI instruments can be seen in the following two different approaches on one side, taxes follow a price approach because producers adjust the quantity, given a fixed price put on emissions on the other side, a tradable permit system follows a quantity approach because the price is adjusted according to supply and demand, given a maximum quantity of emissions allowed.

Application of ion exchange refining to the process for the manufacture of dextrose may be understood from the following description of such a process. Triple-washed starch is diluted with ion-free water to the desired concentration and is acidified with a definite quantity of mineral acid such as hydrochloric or sulfuric. It is desirable that the acidified starch slurry be held for at least thirty minutes in order to permit an effective equilibrium acidity to be reached. The starch slurry may contain a quantity of soft water salts which consume acid, and since this consumption is variable, the acidity is checked and adjusted to the desired level following the holding period. The conversion is then carried out at elevated temperature and under pressure for a period sufficient to yield maximum dextrose. The conversion may be carried out batchwise in an autoclave, or continuously. 

Techniques for extracting juice from the fruit vary with the type of fruit. A complete breakdown of the cellular structure is desired so the sugar is available to the yeasts. With most fruits, however, it is not desired to conduct the entire fermentation in the presence of the cellular material as this permits the extraction of excessive amounts of tannins. One needs equipment that will separate the maximum quantity of relatively clear juice from the fruit before or shortly after the start of fermentation. 

In spite of the many approximations used in deriving this set of equations, the mathematics of solving them is formidable. The set of equations is 2s + 1 in number, where s is the number of species that occur within the flame. Of these, s + r — 1 equations (r < s) form a set of independent equations since the quantities x, and G, are fractions such that Y,iXi = 1 and Y.i Gi = 1, and stoichiometry reduces the number of independent species by some number (s — r), (H3). Part of the mathematical complexity is due to the presence of intermediate species whose concentrations are low in the hot and cold gases but which may pass through a maximum within the flame zone. Since the rates of appearance and disappearance must be comparable for this to occur, it is approximately true near the maximum that Kt = 0 for these species. This fact results in an indeterminancy of the system of equations, although, at the same time, it provides a method which permits an approximate solution to be obtained. 

A directive was adopted in 1978 regarding exclusively materials and articles containing free vinylchloride monomer (Directive 78/142/EEC). It lays down the maximum quantity of free monomer permitted in the finished article as 1 mg/kg and states that such materials and articles must not release to the foodstuffs with which they are in contact any amount of vinylchloride detectable by a method of analysis with a detection limit of 0.01 mg/kg. In 1980 and 1981 two further directives were adopted which lay down the method of analysis for vinylchloride in the finished article and in foodstuffs respectively (Directives 80/766/EEC and 81/432/EEC). 

The decomposition of the standard chemical potentials per amphiphile of the aggregates permits the size distribution function to be written as a product of exp [—[iig/hT)], which is a decreasing function of g, and another factor containing the size independent quantity . If is small, the size distribution is a monotonic decreasing function of g. If, however, is sufficiently large compared to unity, the size distribution can have a maximum. Therefore, a critical value of exists, separating the two kinds of behavior, To compute this critical value as well as the corresponding critical concentration of amphiphile, explicit expressions for the terms of the standard chemical potentials are needed. 

The use of S02 is not permitted in foods that contain significant quantities of thiamine, because this vitamin is destroyed by S02. In the United States, the maximum per-... 

The carbohydrate being eluted from a GPC column can be detected by a number of physical or chemical means (e.g., variation in refractive index or viscosity and colorimetric or fluorometric spectroscopic analysis). For the purpose of these experiments, the cellulose was tagged with a fluorescent label, dichlorotriazinylaminofluorescein (DTAF), which permits easy detection of very small quantities. The chromatographic system was set up to allow for convenient analysis of cellulose with a maximum resolution of the molecular weight distribution and a minimum of change to the sample. 

Shortly after the discovery of deuterium by H. C. Urey, Gilbert Newton Lewis prepared 1 ml of nearly pure deuterium oxide by the continued fractional electrolysis of ordinary water. Since then heavy water has been very carefully studied and new" methods have been developed for its isolation which permit it to be made in large quantities. Its density at 20 is 1.1059 g Vm ", its freezing point is 3.82°, its boiling point 101.42°, and its temperature of maximum density 11.6° C.
