There are, in general, two types of detonation tests [10,22,24]. In one type of test, the propagation of a detonation shock wave is determined. Examples of methods for this test are the BAM 50/60 test [139], the TNO 50/70 steel tube test [120], and the USA GAP test for solids and liquids [140,141]. 

In the other type of test, the strength of the detonation (explosive power) is determined. Examples of methods for this type of test are the lead block test [139] and the ballistic mortar test [141]. Only the first type of test, which determines the possibility of a detonation, is discussed here. 

As an example of method 3, in bubbly flow with a low quality it would be appropriate to calculate the friction factor based on the properties of the liquid. The frictional component of the pressure gradient for the actual two-phase flow is given by...

Many stimulants, such as amphetamine, methamphetamine, and caffeine contain nitrogen atoms, which makes NPD analysis fairly straightforward (eg. Koide et al., 1998 Bach et al., 1999). Enantiomeric separation can be of particular importance for these drugs. A review by Liu and Liu (2002) provides extensive examples of methods for the determination of amphetamine and methamphetamine enantiomers and includes examples... 

As an identity (ID) test, per ICH guidelines, only selectivity is required in method qualification and validation. Repeatability and intermediate precision are often included to ensure reliability of p7 determinations. Additionally, method robustness should be tested to assure that the assay performance is suitable for QC environment. Quantitative parameters such as LOD/LOQ are not required for an ID assay. If a cIEF method is used for purity determination, then all the purity parameters shown in Section 4 should be qualified. The following sections illustrate an example of method development and qualification procedures for cIEF.

An example of method development using porous polymers is the work done for n-butyl mercaptan. n-Butyl mercaptan collected on charcoal was found to oxidize readily to the dibutyldisulfide. It was not feasible to analyze for the mercaptan as the disulfide, because the disulfide could also be present in the workplace. Silica gel was an excellent collector for the mercaptan in a dry atmosphere however, at 80% relative humidity the sorbent collected moisture preferentially, and sorbent capacity was severely reduced. 

One of the main problems mentioned in the talk of Professor Williams was the correlation between the structures and functions of biological compounds, which can be treated as a continuation of the most important chemical problem of correlation between the structures and reactivities. These problems are indeed of extraordinary significance and I would like to mention that besides the nmr (taken as an example of method in Professor Williams talk), other hyperfine interactions are also very fruitful in the investigation of the previously mentioned correlations.

Several of the above approaches have proved appropriate for the preparation of alkylated derivatives whilst related but somewhat modified chemistry is required for other substituted compounds routes depicted in Scheme 24 are examples of methods for the preparation of alkoxy derivatives (47JA2449). Compounds such as 2-hydroxyketones and 2-mercap-toketones dimerize reversibly to give 2,5-dihydroxy derivatives of 1,4-dioxanes and 1,4-dithianes respectively (B-57MI22600, 66HC(21-2)104l). 

An LC-MS/MS method [34] will be described in detail in order to serve as an example of method development and validation. This method allows the determination of some of the most common antidepressants used in clinical practice and some of their main metabolites in oral fluid and plasma samples. 

An example of method application to a study to assess the possible correlations between antidepressant concentrations in plasma and oral fluid will also be discussed in this section.
