Technique, defined

This is the ASTM D 2892 test method and corresponds to a laboratory technique defined for a distillation column having 15 to 18 theoretical plates and operating with a 5 1 reflux ratio. The test is commonly known as the TBP for True Boiling Point. [Pg.18]

Energy is one of the most useful concepts in science. The analysis of energetics can predict what molecular processes are likely to occur, or able to occur. All computational chemistry techniques define energy such that the system with the lowest energy is the most stable. Thus, finding the shape of a molecule corresponds to finding the shape with the lowest energy. [Pg.7]

Why should we study the structural properties of the channel macromolecules themselves Although biophysical techniques define the functional properties of voltage-sensitive ion channels clearly, it is important to relate those functional properties to the structure of the channel proteins. We focus first on the discovery of the ion channel proteins, in which three different experimental approaches were used... [Pg.101]

Oxidation of dihydroquinacridone to quinacridone may be achieved, for instance, with the sodium salt of m-nitrobenzene sulfonic acid in aqueous ethanol in the presence of sodium hydroxide solution [7]. A distinction is made between heterogeneous and homogeneous oxidation. The reaction is referred to as a solid state oxidation if the solvent contains approximately 2% sodium hydroxide solution. A content of approximately 30% sodium hydroxide solution relative to the solvent mixture, on the other hand, converts the reaction into a so-called solution oxidation . The type of ring closure defines the crystal modification of the resulting dihydroquinacridone, while the oxidation technique defines the crystal phase of the quinacridone pigment. [Pg.455]

Another important part of IQ is the generation and approval of an instrument-operating procedure, if applicable. This procedure defines the use and care for a CE instrument. This generic procedure is useful to train new analysts on the technique, define the requirements for routine and corrective maintenance, and other relevant information. [Pg.58]

Hirschfeld, in his article on coupled techniques, defined, a hyphenated instrument as one in which both instruments are automated together as a single integrated unit via a hardware interface. . . whose function is to reconcile the often extremely contradictory output limitations of one instrument and the input limitation of the other (22). Therefore, the key to combining SFE with chromatographic techniques is the interface which should allow the optimum and independent usage of each instrument while the couple still operate as an integrated unit (23). [Pg.138]

These processes, included in a special class of oxidation techniques defined as advanced oxidation processes (AOPs), are based on the irradiation of a semiconductor photocatalyst with UV light that leads to the formation of highly reactive hydroxyl radicals. [Pg.335]

The terms that appear in the energy resulting from the above wave functions are easily found using the diagram technique defined in Sections IX and XIII. Take, for example, the x> first and substitute in the E of Eq. (58). In each term use the fact that commutes with... [Pg.350]

It is noteworthy that, although many SCFs have been investigated as precipitation media in all of the techniques defined above, CO2 is the one most often considered and used, because of its particularly favorable properties. [Pg.109]

As it stands, the equation describing transient velocity is inhomogeneous, and a separation of variables approach will fail. This can be remedied by the following technique. Define velocity as being made up of two parts, a steady part plus a deviation from steady state... [Pg.465]

Detailed investigations of the main dynamic characteristics have been performed for the prototype church in both orthogonal directions by applying the ambient vibration technique. Defined in this way were the natural frequencies 4.8 and 6.0 Hz for the N-S and E-W directions respectively. [Pg.118]

Spatial resolution of an analytical technique defines the ability to extract and separate analytical information from regions of a sample with a typical diameter in the range of microns. The novel aspect of spatial resolution is to image the distribution of elements or compounds across the sample surface. The in situ analysis of microscopic areas of the work of art may be accomplished by spatial resolution, thereby the extraction of a wide range of valuable analytical information can also be visualized with an image. Spatial resolution also allows for the analysis of tiny fragments of samples scraped from the object of interest with minimal damage to the artifact itself. [Pg.845]

Thermal conductivity, which is an important parameter for thermal assessment of the core behaviour in the safe-storage safety case, is derived from thermal diffusivity measurements which employ a laser heat-pulse technique defined by a British Standard method (BS 7134 Part 4.2, 1990). [Pg.221]

A second technique defines the minimum bubbling velocity as the velocity corresponding to the maximum bed height. [Pg.330]

In general, analysis type defines the what and when to analyze for safety, while the analysis technique defines the specific how to perform the analysis. [Pg.339]

An HA technique defines a specific and unique analysis methodology that provides a specific procedure, along with a specific type of expected results. The overarching distinctions of an analysis technique include the following ... [Pg.340]

NOTE — The above technique was used in addition to impiementation of the techniques defined in iSA-84.01-2004, Part 1, Clause 12. [Pg.38]
