The chromatogram can be sprayed with Uquid paraffin — n-hexane (2-1-1) to increase the fluorescence intensity [2]. The detection limits per chromatogram zone are 0.5 — 1 ng for cardiac glycosides [5], triglycerides [6] and sterigmatocystine [2] and 25 pg for estrogens [7]. 

Immersion in a Uquid paraffin - n-hexane (1 + 3) did not lead to an appreciable increase in fluorescence intensity. 

The MMP Sorbex process has many similarities but also some differences when compared to the detergent Molex process. As with all of Sorbex processes, the MMP Sorbex process operates in the Uquid phase, employing suitable conditions (pressure, temperature) to overcome any diffusion constraints to achieve target performance. Table 8.4 highlights and contrasts the different characteristics of the detergent Molex and MMP Sorbex processes. The process was successfully demonstrated in a continuous countercurrent moving bed separation pilot plant using commercial n-paraffin-depleted kerosene (Molex raffinate) feedstock. A typical gas...

Another technique, used mostly in the past, is to muU the powder with liquids, such as liquid paraffin (nujol) and perhalogenated organic liquids. The powder is mixed to make a paste from which a layer is formed. Obviously, absorptions from the mulling Uquid (e.g. in the C—H stretching and deformation regions for paraffin oils, or C—X modes for halocarbons) also occur and obscure some spectral regions. 

Uquid paraffin and decalins were purified by column chromatography on activated silica gel and alumina. Viscosity of liquid paraffin was measured by Ostwald viscometer. Spcctrograde n-hexane and cyclohexane were used without further purification. All solutions for the measurements were deoxygenated by flushing with nitrogen gas.

The physical change of a liquid to a solid by temoval of energy as heat is called freezing or solidification. Perhaps the best-known example of freezing is the change of Uquid water to soUd water, or ice, at 0°C. Another familiar example is the soUdification of paraffin at room temperature. All liquids freeze, although not necessarily at temperatures you normally encounter. Ethanol, for example, freezes near —114°C.
