Immersing device

Substances that cannot be directly measured in UV/VIS or F mode can generally be quantitated after chemical derivatisation [404]. Transfer of derivatising reagents onto the plate can be accomplished by spraying or by immersing the plate using an automatic immersion device. Such a device controls the immersion rate,... 

The electrical characteristics of the TSM resonator with a generalized surface perturbation can be described by the equivalent-circuit model of Figure 3.7b. Measurements can be made on a dry TSM resonator to determine C o,L, Ci, and R. Fixing these parameters and fitting the equivalent-circuit model to data measured on an immersed device determines R2 and L2. Equations 3.21 can then be used to determine the components of from L2 and R2.

Homogeneous matrix coating is performed by immersion of the chromatogram into a 2,5-dihydroxybenzoic acid (DHB) solution using automated immersion devices (Desaga or CAMAG). After the rapid dipping (immersion time 0 s immersion rate 4 cm/s) the plate is dried with a hair dryer for some seconds (until the shiny...
