Periodates analysis

Regarding concessions you will need to register all requests for concessions to product requirements and carry out a periodic analysis to detect trends. Is it always the same product, the same requirement, the same person or are there other variables that indicate that the requirements are unachievable and in need of change Under ideal conditions there should be no need for requesting concessions. The process should be fully capable for producing the goods. But if it happens frequently, there may be some underlying cause that has been overlooked. [Pg.465]

Your planning and delivery procedures need to record estimated and actual delivery dates and the data collected and analyzed through a delivery performance monitoring procedure. When targets are not met you should investigate the cause under the corrective action procedures and formulate corrective action plans. Where the cause is found to be a failure of the customer to supply some vital information or equipment, it would be prudent not to wait for the periodic analysis but to react promptly. [Pg.486]

In some cases periodic analysis of the seal fluid should he done to check for the accumulation of fouling materials, such as gels, which may he due to reaction of the seal fluid with process gases and materials. [Pg.128]

Self regulating chromium The self-regulating chromium solutions were introduced to eliminate the need for maintaining the correct catalyst concentration by periodic analysis they depend on the addition of a sparingly soluble sulphate to the bath which supplies the correct amount of SO 4 automatically. Initially strontium sulphate (solubility approx. l-75g/l at 30°C and 21 g/1 at 40°C) was employed for this purpose. The strontium sulphate forms a layer on the bottom of the bath, which must be stirred from, time to time. A bath with a CrO, concentration of 250 g/1 would have a catalyst content of l 52g/l SrS04 and 4-35 g/1 of KjSiF. Potassium dichromate and strontium chromate have also found application as additives for the control of the saturation solubility of the catalyst. [Pg.546]

Bedding can be purchased that is guaranteed to be free of potentially interfering contaminants. In the absence of such a guarantee, the laboratory may wish to consider its own periodic analysis of bedding for contaminants. [Pg.91]

To determine the stability of the test and control articles in the mixture as required by the conditions of the study either (i) before study initiation, or (ii) concomitantly according to written standard operating procedures which provide for periodic analysis of the test and control articles in the mixture. [Pg.96]

Only seven published studies exist regarding the effects of a small number of antidepressants on computerized sleep EEG patterns [Jarrett et al. 1988 Kupfer et al. 1991, 1994 Minot et al. 1993). In these studies, only 118 total patients were included, and no confirmatory study was done for any of the drugs. Moreover, the length of the drug administration period varied from 1 day (Jarrett et al. 1988] to 3 years (Kupfer et al. 1994], and the method of computerized analysis was not uniform some studies used period analysis (Jarrett et al. 1988 Kupfer et al. 1991], others used fast Fourier transform (Minot et al. 1993 van Bemmel et al. 1992b, 1993b], and some others used both period analysis and fast Fourier transform (Kupfer et al. 1994). [Pg.265]

Collects information, maintains a database of botanical applications, and performs periodic analysis on the status of botanical new drug development. [Pg.322]

Periodic analysis of makeup and cooling water samples, and possibly other water sources, or samples of scale or other deposits and foulants. [Pg.368]

To determine the stability and, when relevant to the conduct of the experiment, the solubility of the test, control, or reference substance in the mixture before the experimental start date. Determination of the stability and solubility of the test, control, or reference substance in the mixture shall be done under the environmental conditions specified in the protocol and as required by the conditions of the experiment. Where periodic analysis of the mixture is required by the protocol, there shall be written standard operating procedures that shall be followed. [Pg.152]

Small production units without access to laboratory facilities should seek the help of feed suppliers in carrying out periodic analysis of ingredients. Other agencies such as government, university or commercial laboratories may have to be used. [Pg.242]

During the exposure period, analysis should be conducted as often as necessary to determine the consistency of particle size distribution. [Pg.492]

In addition, the testing laboratory for both nutrients and unintentional contaminants, including carcinogens, may perform periodic analysis of the basal diet. The results of such analysis should be retained and included in the final report on each chemical. When the test chemical is administered in water or food, stability tests are essential. Properly conducted stability and homogeneity tests, prior to the chronic study, should be used to establish the frequency of diet preparation and monitoring required. When diets are sterilized, the effects of such procedures on the test chemical and dietary constituents should be known. Appropriate adjustments to nutrient levels should be performed. The effect of chemical sterilants, (e.g., ethylene oxide) on the bioassay should be ascertained. [Pg.497]

All safety staff stressed the importance of occasional ad-hoc reactions (after unique incidents with possibly wide implications for other parts of the industrial system), next to the need for more structural measures based on periodic analysis of the entire NMMS database. [Pg.67]

It is obvious that essentially the same structural possibilities result from the methylation or periodate analysis of starch, particularly amylose. With starch, the evidence has been predominantly in favor of (a). [Pg.246]

The catalyst may be also preformed separately on a large scale and is stable over a long period. Analysis of the product mixture indicates only small amounts of byproducts such as butadiene dimers. On a technical scale, unreacted butadiene is easy recovered and the process can be optimized with respect to TON and selectivity. Further studies of several reaction... [Pg.131]

Another type of stability of immobilized biocatalysts is the retention of activity after periodic use in batch processes, as has been reported previously for penicillin acylase entrapped in polyacrylamide gel [40]. This option can be used to advantage for rapid monitoring of biocatalyst activity under conditions of industrial application. Apart from the measurement of activity as an indication of the necessity to replace the biocatalyst, the periodic analysis of the variation of kinetic properties permits greater insight into deviation from the optimal parameters. [Pg.91]
