In Fig. 6, on the left (a1, b1, c1), all drying steps are present, whereas on the right (b2, c2), the drying steps were reduced to a minimum.
These strips are coated again, drying steps were repeated, and weights are recorded.
The [18F]fluoride solution was then dried, and two azeotropic drying steps were performed with acetonitrile (unit operations 4 to 8).
The crystals were obtained by following vacuum-filtering, washing, and drying steps as in the synthesis of zeolite Beta.
No drying steps (e.g. for the fresh products) were conducted and all results refer to fresh weight.
Ester loss due to the formation of emulsion during the washing and drying steps was 15% maximum.
After the centrifugation, washing and drying steps the total mass of CLEAs recovered was 95.5 ± 2.6 mg (Column "Total mass of CLEA recovered" in Table 3).
In fact, moisture displacement during wetting / drying steps appears to exert a linear control on the amplitude and rate of movement.
Coatings of varied thickness were produced by repeating the deposition step two or three times accompanied by drying steps in between.
The total lipid FA from 100 µl plasma is transferred in situ into methyl esters, avoiding initial extraction and drying steps.
The method is robust and simple, because lipid extraction and washing steps as well as neutralization, centrifugation and drying steps are avoided and only one FAME extraction step is required.
