Screening-Methode

Another application of laser-based profilometry is the inspection of rocket and missile components. The U.S. Air Force has funded work to develop a non-contact laser-based profilometer for the inside surface of solid rocket motors. Over time, these devices are subject to slumping and cracking, which could potentially render the rocket motor ineffective and hazardous. When fully implemented, this system will provide a meaningful screening method for evaluating the condition of aging rocket motors. [Pg.1066]

Nitrate can also be measured potentiometrically with an ion-selective electrode at 10 10 M (24,25). This method is suggested as a screening method for determining the approximate nitrate concentration (20). Ion chromatography can be used for nitrate concentrations of 2 to 10 ppb (23). [Pg.231]

After screening for toxicity, identification and/or quantification assays may need to be carried out if the screening method is not specific for the cyanobacterial toxin(s) under investigation. Suitable assays for these purposes include the physicochemical assays, HPLC, MS, and CE, and to some extent the immunoassays and protein phosphatase inhibition assays summarized in Section 2. [Pg.120]

The aim of most screening methods is to produce a yes/no decision, concerning whether the concentration of a certain substance in a sample exceeds a given limiting concentration or not. For instance, if the concentration of a substance lies below a permitted maximum concentration then there is probably no need to analyse the sample. However, if the content is in the region of or above the permitted limit, then the result must be confirmed by means of an exact quantitative determination. [Pg.30]

Such yes/no decisions are of great importance in foodstuffs control and environmental analysis. They also play an important role in pharmacy in the form of content uniformity tests. Without suitable screening methods for rapid detection of positive samples it would scarcely be possible to carry out economic doping controls and toxicological investigations or to recognize medicament abuse. [Pg.30]

The unequivocal recognition or exclusion of particular substances in question is of especial importance for such screening methods. As far as the chemist is concerned this can involve a deliberate search for substances with particular functional groups particular questions that might require answering might include the following ... [Pg.30]

Gonzalez, M., Gallego, M., and Valcarcel, M., Automatic screening method for the rapid and simple discrimination between synthetic and natural colorants in foods. Anal. Chim. Acta, 464, 237, 2002. [Pg.528]

A systematic study was carried out using in parallel 50 standard solutions for each concentration of three natural colorants (curcumin, carminic acid, and caramel as yellow, red, and brown, respectively). No false positive results for synthetics were obtained up to concentrations of 15 and 20 ng/ml for natural red and yellow colorants, respectively, or 110 ng/ml for natural brown colorant. The concentrations have to be high enough to prove that the screening method is able to accurately discriminate natural and synthetic colorants. To make a clear interpretation of the quantitative UV-Vis spectrum, linear regression analysis was used. Quantitative UV-Vis analysis of a dye ° can be calculated according to the following formula ... [Pg.540]

Risk assessors tend to build in additional uncertainty factors to avoid healthrelevant underestimates. This is partly done by using screening methods designed to look for worst case situations. Such worse case assumptions lead to intake estimates that exceed reality. For chemicals that present potential risks, more information is needed to allow more refined screening or even the most accurate estima-... [Pg.569]
